Online backup to Google Drive, Amazon Glacier, SFTP.

Overview

Arq is super-easy online backup for Mac and Windows computers. Back up to your own cloud account (Amazon Cloud Drive, Google Drive, Dropbox, OneDrive, Google Cloud Storage, any S3-compatible server), your SFTP server, or your NAS. On OS X, Arq backs up and faithfully restores all the special metadata of Mac files that other products don't, including resource forks, ACLs, and creator codes.

  • Following the initial backup, Arq automatically makes incremental backups every hour, every day, uploading just the files that have changed since your last backup. Arq keeps hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for everything older than a month.
  • Arq lets you set a budget for storage, and it automatically drops the oldest backups to keep within the budget.
  • Arq backs up everything with no limits. It backs up files of any size, external drives, and network drives.
  • Arq compresses and "de-duplicates" your backups, never storing the same file twice in the cloud. Arq encrypts all your backups with a password that never leaves your computer, so no one can read your cloud backups.
  • You can back up to multiple accounts. Back up some files to Glacier, some to S3, some to an SFTP server, etc.

What's new in Arq

This failed right out of the gate. I couldn't backup anything because the SMTP host wasn't set. I didn't configure email. Tossed in the trash.

I used the app for many years, but stopped doing so due to 3 short-comings a while ago: (1) It is not possible to migrate backup data from one cloud provider to another, which I might want to be able to do in the case of pricing or service changes (B2/Amazon Drive), new providers (Wasabi), lack of reliability, etc. If I want to retain my historical backups/archives, I am locked into the originally chosen cloud space vendor forever. This for me was the main show-stopper; the company behind Arq has stated multiple times over the last years (both on Twitter and via eMail) that this lock-in is a known fact and provider-migration is not supported. (2) Arq is very destination centric, rather than source centric. One cannot create one file selection for backups and then back this selection up to multiple destinations, rather one needs to manually recreate the selection for every destination, and keep it in sync manually. (3) The Arq Backup agent requires a significant amount of CPU cycles. A well-equipped 2015 MBP became unusable every time Arq was performing a backup, which made Arq unsuitable for continuous backups.

I run QR on all of my Macs plus recommended it to all of my customers. It's fast and the deltas are very small. I use it instead of time machine since these backups run seemingly forever and copy huge amounts of data. In addition to QR I run CCC for bootable alternative device and managing local filesystem snapshots as they are possible in APFS. The most important data is saved additionally to the cloud via Arq. Never had any problem. The dev responds very fast and complete on questions. This triumvirate is my favourite combination to save my data.

I've been using Arq for several years on my Mac. It has worked flawlessly. I'm very pleased with it. Also, I've switched from using Google storage to Backblaze - now my entire disk is backed up for around $1.50/month. It makes the cost of the software very worthwhile. It never uses a lot of CPU and doesn't slow down my internet or disk access. I'm a very satisfied customer.

This app is fantastic and deserves 5 stars, it's rock-solid, no doubt about it. Anyway, there should be an option to password protect the application itself when you don't want users, children, wives ? to mess around with settings and backup selections. Last, on my five Windows 8 and 10 machines (this doesn't happen on macOS), Arq loses email settings, the email pane reverts to blank after two or three days, so I get no alerts o messages about backup completion.

It's the backup solution I've been using for the last 5 years. It's fast, easy on resources (CPU, memory), can customise and filter what's uploaded. I'm backing up to S3 and Backblaze and paying about $1 per month. (Photos are handled by iCloud)

Love this app, it encrypts our data before uploading, downloads and being we backup hourly it even intelligently names the files accordingly. Minus one star because we have to use BackupList+ for local Clone/Mirror of HD locally because Arq doesn't perform HD Cloning.

One of the very best backup solutions for Mac and importantly a very responsive developer. All my data is in Amazon S3 and all my Music and Photos in Amazon Glacier. Works perfectly on OSX 10.12.5 b3 too. When I sort my Google Business account, will probably add Google Drive as a second destination for key data, Highly recommended.

One of the best and easiest backup apps for the paranoid (meaning your backup set is encrypted for cloud storage) ... . I think it's also important to note that the "adopt backup" on a re-installed computer works well. I recenlty reinstalled my MacBook and setting up backup with an already existing backup set on Amazon Cloud was a breeze. I am running Arq Backup on 10.12.1 without a problem once it's setup, it just runs in the background quietly and efficienlty.

Very good piece of software and backup solution for OS X and for Windows. (Buy only once and use it on both systems!)

Very responsive and competent developer.

Full star rating and definitive recommandation for everyone with a mac or a pc (every OS X or Windows User).

The world would be a better one, if every OS X and Windows User would use this backup software. Regarding Data Safetiness the last sentence is nothing less or more than the truth.

Overall im very happy with Arq, but the UI could definitely be more UX friendly and better looking. Also, and this is a big deal for me, I'd appreciate support for other popular Cloud services. First and foremost I'm thinking about Hubic by OVH, which offers extremely good transfer speeds, is based in France (not USA) and for $5 a month you get 10TB of space. This is a killer combination because you essentially get CrashPlan or Backblaze competitive pricing.

I have tried a lot of different backup solutions and Arq is the one I ended up going for. The fact that I can use SFTP means that I can backup to any of my computer, or even off-site to friends computer for that matter. What I love is that I can chose where my data will be backed up and know where it is going. S3, google, Amazon, ... A lot of backup solutions exist and some are very good but none can offer the following four features the way Arq can. 1) Simplicity: Yup, it's a feature. Over complex backup solutions with a zillion options will only increase the risk of mistakes and loss of data. A backup solution has to remain simple and efficient. 2) Encryption: Knowing that your data, wherever it may be, remains protected and for your eyes only. On that note, the restore process has been open-sourced so even if Arq goes down in flames (which I hope will never happen), you can always recover your data independently from the Arq software! 3) Choice: I can not think of any online backup solution that offer you this much choice on where to store your data. Some allow local backups, most are using Amazon for they online backup solution but Arq just keeps adding storage providers to the list. 4) Support: Simply great. If you ever have an issue, send them email and they will always reply. Thanks Arq for keeping my family pics safe!

I'm retired now and get time to do the things I like - like playing with backup tools on my Macs. I've tried tens of solutions and continue to play, but for my real backups I use Arq - it's solid, can choose where I store my data (and in multiple places) and the developer gives solid support. Yes there's many tools that are just as good, but this one just gives me a warm feeling.

So far, so good. I have been using the software for quite a while now (OS X version) and it does the job to the extent one can tell! With any backup software you need to try and test your backups and, of course, have faith in the entire process). Of course there are things that the developer could improve on - there is no megacorp behind the company here - yet the developer should be credited for the work done so far. From my own experience, a lot of the "problems" are caused by the backup destinations being used. OneDrive seems to be like a snail overdosed on sleeping tablets (no matter what location I try and emerge from) and the newly added Amazon Cloud Drive has been rather problematic (the developer is having to go to the ludicrous situation of trying to fix Amazon’s own problems and shortcomings in software as a temporary measure). Google Cloud seems to work and my own S3-based instance has been trouble-free. My own extensive troubleshooting experiences with the developer have been positive. Of course, you want faster responses as obviously your own problem is the biggest thing in the world (self-referential irony) but practically you know that there are many customers to support, future developments to code, bugs to fix and maybe even find the occasional hour for “me time”. If the user is able to give additional information above “it don’t work” this can help or speed up the process. It would be nice to get a roadmap of planned developments, a feature request list and other fine things, yet Rome wasn’t built in a day. It does feel that uploads are slow, even when backing up on the LAN, compared to non-encrypted transmissions. It can be a perceptional issue or areas of speculation that may be improved in the future. It would be highly desirable to have a bandwidth usage meter so you can see it is currently backing up at X speed, then you can have an idea that backups to OneDrive usually are around X Mbit/s, Amazon X Mbit/s etc. For those with more powerful computers and several backup locations, multiple (simultaneous) backups would be good, especially when uploads don’t tax your uplink speed and you have a lot of data to initially seed. If you don’t feel the developer responds quickly, maybe he has not got the mail (there was a problem in the past with the “request support” link in the software. Email has worked and the developer also answers Twitter. TL:DR: Still a best of breed and getting better, despite the provocation some backup sources can create when they break things at their end.

I've used Arq for more than a year now backing up my MBP (around 300-400G of data) via SFTP to my Mac mini in the cloud. Not only is the backup data encrypted in transit but also when it sits on the server (albeit in this case the server is mine). I had a few minor issues initially but the developer himself (Stefan) always responded very quickly and helpfully to my e-mails to fully resolve the issues which I had. Since then, Arq has worked perfectly in the background keeping my MBP backed up without any effort on my part. The user interface is not fancy but does the job. The developer even provides Git source code for a program to restore Arq archives in the (hopefully very unlikely) event that the company is no longer around (I complied this and it works fine to restore my backups). Arq is one of the crucial parts of my multi-backup strategy and I'd highly recommend it to anyone looking for a robust remote backup solution.

Used this for approx 6 years and I've only had one problem with Arq in early 2012 but nothing whatsoever since then. Take a deeper look at customers' feedback on other cloud backup solutions and you'll see that's pretty darn good. The only downside about this software is that the backups are currently so good and so secure (they retain A+ metadata and are sent to Amazon servers on my S3 account), that I've become a bit casual in backing up and cloning to external hard drives, which is something we should all do. But the fact that Arq continuously backs up my files all the time flawlessly without me noticing or even thinking about it gives me massive peace of mind.

I really wanted to like arq. A windows version was released and OneDrive is supported. I downloaded both versions and tried them. I'm backing up around 800GB on the mac and 400GB on the PC.

The mac backed up about 500 GB and simply stopped. The icon on the menubar is animated, but my OneDrive icon on the menubar isn't animated because no data is being written to my OneDrive. I've stopped and restarted the service. Reinstalled the service. Rebooted the machine. Nothing. I've contacted support. No response.

Exact same thing has happened on the Windows machine. It backed up around 100 GB and it continually stays and repeats in an "Estimating upload size..." loop. I've contacted support as well. No response.

I wanted to like it. I could buy 2 licenses, use OneDrive, and save a ton of money by dropping Crashplan. But Crashplan works and Arq doesn't.

I tried Arq after Steve Gibson enthusiastically recommended it on his Security Now! podcast. Steve verified Arq's bulletproof encryption and security. He said it was so good it was almost enough to make him switch from PC to Mac. Steve also likes the Arq model of buying your online backup software separately from buying your online storage space. That way you can change online storage providers as you wish based on price and features. I love Arq. It is essentially Time Machine for online backup, with versioned backups and the ability to set a budget for determining how long older backups are retained. I use it with Amazon S3, though there are many other choices for storage. It is dead simple to set up and use. It has been 100% reliable for both backup and restore. And the support, from the developer himself, is excellent. Both the software and the online storage are so inexpensive that there's really no reason anymore not to take advantage of the tremendous safety benefits of online backup. Highly recommended.

I really like(d) Arq but after a few months of unexplainable problems with my computer (slow, stalling, etc), I now discovered that Arq has been causing this. I installed a ram emptier app and today it reported that that it had saved an unbelievable amount of 17 Gb (!) of hidden ram usage from Arq (i have 24 gb installed but even that wasn't enough with only Mail and Arq opened simultanously ....). So it is safe to say that at this point Arq is useless and causing major problems with your computer. Big Time Bummer because I really liked Arq. :-(

I'd like to add two points to the general consensus that this software is exceptional. 1. Communications: The author is extraordinarily (literally so) receptive to bug reports and feedback. He often responds within minutes to an email to the support address -- and doesn't merely parrot links to what the support pages on the site say; but gives detailed information about why whatever is happening is happening. I find this reminiscent of the old shareware days and it's really just phenomenal to experience on the rare occasion you need to ask for help. 2. Features: Yes, this is backup software; but the point is that this is that thing you (if you're a programmer) have often dreamt of writing yourself. It's backup software that stores to all of the cloud stores you could want (yes, it has Glacier, yes it has Google and Microsoft's Cloud, yes it even has support for the new GCS low cost store which has only been out for a week, etc.). And it just works - what it's doing isn't magic, it's doing exactly what you'd want - generating journals, encrypting things locally, pushing them to the cloud, etc. It's a superlative piece of software and worth every cent.

I have been using Arq 3 for the last couple of years - and really appreciated the app. With the release of 4.10.2 I decided to upgrade. I ran into a problem installing the upgrade on the 3 Macs in the household. However, after contacting Stefan at Haystack, he was able to help me troubleshoot the challenges. The support was immediate and positive - there are many gaps in my IT knowledge! I know have the latest version of Arq running smoothly. Great product, great support. Thx

Until now I really love Arq but is there a way to avoid Arq generating these -- huge -- cache files in user/library/arq/Cache.noindex? One even filled up my drive .. :-(
Would give Arq a 5 star when the cache file generation is stopped or it can be limited/set through preferences setting.

One of the most reliable backup solutions I know. Easy to use, no frippery, fast and secure. I backup all my macs and those of some of my friends in different buckets and pay just a few bucks every month. Tip: Store your S3-credentials and Arq-Passwords on a safe place, f.e. in 1Password. If they are lost your data is gone!!!

The simplicity, sits in the menubar, backs up whatever is selected, at whatever time you choose - never had a problem since the beginning. Don't honestly know why use anything else—and people who think Dropbox is the same thing, nooo. Nor is SuperDuper, a great app for making a clone, for one thing. Arq is your solid off-site backup, and it's so easy to "restore" a file - send this man money.

I tried really hard to love Arq. When it works, it's brilliant. I have it purchased and deployed at 4 different client sites. Three of them work flawlessly, invisibly in the background, providing offsite backup at a very low cost and no user intervention required. But the other site. It crashes their server within 36 hours of launching every time. I've tried upgrading their server OS (was 10.8.5, now 10.9.4), upgrading the app, quitting every other third-party application (including all drivers and helper apps), rebuilt all the volumes, etc. It keeps killing the server. It may just be that they have too much data — they're backing up around 8TB at the moment — but there's no published limit. Which brings me to the worst part.... I emailed the support. He wasn't very helpful. At all. I sent him the debug logs. His response was "I can't reproduce the error." Well great, lucky you. I sent him all the requested details on the types of files, configuration, etc etc. And then he just stopped replying to me. It's not like I was abusive or rude in any way, he just hasn't replied to any of my messages in over a week. So. Great app when it works. When it doesn't.... well, I guess you have to hope the developer can reproduce the issue??

I have used Arq since v1. I have used a variety of other cloud backup solutions (in addition to local solutions that I use in parallel). Arq is in all respects superior to any other cloud solution — your data is not tied to Backblaze or Crashplan, but rather stored on Amazon (and now Google), the application is incredibly stable and reliable, and the developer continually improves the app and adds features. Great App!

This is a really nice piece of software. I have been looking for a cloud backup for a while, and this fits the bill. TimeMachine like behavior, encryption before the data goes out into the cloud, easy to use (set up and forget), simple to use interface. On top of that it gives you the ability to set the amount you are willing to pay for storage. Arq will go in and delete older versions of files if the expected bill will go beyond the limit. Nice! Overall I'm very happy.

Arq is an incredible backup solution: easy to use, reliable, great Mac interface, fast support from the developer, and rock solid. I backup a ton of stuff to Amazon A3, and some very large folders to Glacier, all for less than $2/month. Version 4 adds many new useful features.

This software is amazing. Versioned, appropriately aged backups. It's like having an Infinite Time Machine, or at least as infinite as your resources and budget allow. My photographs and anything else I've painstakingly worked on are backed up regularly using Amazon S3's Glacier storage class, and nearly 600GB is costing me about USD$4/month. Using the more readily available S3 storage class is a bit more expensive, but my current working catalogs for Lightroom and Documents live there. I know that I can now use my local Time Machine volume for convenience and, in case of emergency, recover with Arq. This software has already saved hundreds of hours of my spouse's dissertation research once, which not only makes it a bargain at twice the price, but it enabled me to be the conquering hero which I can't even put a pricetag on. I should mention I recovered this research using the Arq mobile app. \o/ The addition of other storage providers including/especially *any existing sftp server* is fantastic.

So wait a second here, while Amazon has lowered prices, DreamObjects is still, for all practicality, 1/2 the cost of these reduced prices! Why are we not yet able to simply plug in the DreamObjects server information into Arq? I use DreamObjects on some large projects where we already use it for hundreds of gigabytes worth of storage and I would prefer to use Arq with this instead of Amazon. Can we please be allowed to plug in DreamObjects instead of AWS? Seriously folks, it's literally only changing server names as DreamObjects is fully compatible and will require you to change nothing else in Arq.

Has anyone used this with DreamObjects? I am suspecting that it should work without a hitch, but I'd like to find out before investing in this. DreamObjects is a lifesaver in terms of cost and even performs really well so far for other applications I've used it on.

Just a note that after 1 1/2 years of use with Arq, I somehow lost all my backups. I don't have any real idea what happened but 500+ GB of data that I uploaded to Glacier, and 100+ GB that I uploaded to S3 aren't accessible through Arq. It wants to upload them again, which takes weeks, and that's not great. I don't know what caused this to happen (I'm a fairly savvy user), but what I do know is that in a weeks' worth of emails to Haystack, this hasn't been resolved and I'm no closer to things than I was. I'm not one to leave crappy reviews places, but this isn't the first time I've had Arq lose track of things and force me to re-upload everything (previously was due to a bug in one of the 2.x releases). It could be an Arq problem, or it could be something on the S3 side, but I haven't had satisfactory resolution and when you go with one vendor for software and another for storage there's no single throat to choke, as it were. I'll give Haystack another couple days to respond (responses are delayed 2-3 days and generally not helpful at the moment), but I'm pretty disappointed :-(

People are comparing this to SuperDuper? Which is a fine app -- it's just not the same thing at all. Massive confusion everywhere--no thanks to Apple--between backup and clone. Arq is recommended *way* over TimeMachine. Restore is drag and drop, single file to folder to directory.

I love this app. Many options, you can customize what you backup, rate limit you network speed, set it so the MAC doesn't go into sleep mode during a backup. The issue is the upload speeds from my residential ISP. Over 24 hours I was able to back up 10GB. Until my upload speeds are faster I will not be able to backup everthing I wanted. Setting up Amazon S3 was a breeze.

Arq hasn’t been correctly backing up to Amazon S3. As a result, the developer has provided a fix whereby previous “backups” have had to be re-uploaded. This isn’t the end of the world for anyone that has a few essential files and folders backed up but for anyone who has to rely on this for all of their data, it’s a very serious issue. If, for example, Arq has been “backing up” most of your Home Folder/ Hard Drive, then that means a period of two months waiting for it to do it all over again. Say, 6 weeks into this process, your hard drive fails, would you be able to restore a file that was on your HD a week before? No you wouldn’t because instead of backing up that week old file, Arq would have been re-uploading files it should have uploaded properly in the first place. So on the downside, Arq, in practice, hasn’t been working like time machine; it hasn’t automatically make incremental backups every hour/day; it has uploaded far more than just the files that have changed since the last backup; it hasn’t keep previous backups in the way that the developer claims. On the upside however, it does everything else the developer says it does, the developer provides good and honest support and metadata restoration of files that Arq does manage to backup can’t be beaten. As such I can only recommend Arq for the purpose of backing up only essential files and folders and not all of your data.

I did a very thorough investigation of all the online backup options available and settled on Arq. Here's why (in no particular order): 1. Value - One time purchase of a $29 license, no recurring subscription. 2. Lightweight - not bloated or buggy and works well. 3. Security - Arq is just a nice GUI app to get your stuff on S3, the developer has no access to your data 4. Reliability - After reading about issues with other popular online backup services (Carbonite, Crashplan), and knowing the stability of Amazon S3, it was easy to chose Arq. 5. It has almost everything I want, and one of the options I would like to see, the developer is already looking to add (optional backup to external HDD) In regards to anyone questioning the S3 pricing and how its not a flat rate like other backup providers - My current S3 costs are comparable to other online backup providers, but if I add more data and wind up paying more, I don't care, my data is worth more than $60-$70 a year. Isn't your data worth it as well? P.S. Thanks MacUpdate, Arq went on sale right when I started testing it....$19.00? I couldn't buy it fast enough.

This software is awesome! I am using it to backup all my critical files to Amazon S3. Backups are very efficient (incremental) and you get a simple and clean interface to recover your data (drag-an-drop) Thank god no more over-bloated visual effects from Time machine ... It saved my a** countless times. Takes a few seconds to recover an overwritten file etc.

There is a potentially devastating bug if you upgrade from 2.x to 2.4 that can cause complete data loss on the remote S3 server. This happened to me and was acknowledged by the author. Up to now, I've felt the product and support were excellent, but I'm greatly disappointed that, to date, there has still not been a proactive hot-fix, or notification from the author warning that some users may be at risk of the type of data loss that I experienced. Fortunately, Arq is only part of my overall backup strategy, but I could have been in a really bad place if it was all I had. Just to be clear, 2.4 itself works fine, but if you upgraded from 2.x to 2.4, there seems to be a risk. The "fix" for those that upgraded from 2.x is a simple manual process. Contact Arq support for details.

The maxim "you get what you pay for" should always be applied when considering this type of app and for me, this is the best online backup for a Mac. Reliability and security should be the priority when considering backup, not cost. Obviously, the utilisation of Amazon S3 plays a significant part in making this product great, but just as important is the restoration of data and support of the developer both of which are proven. In this regard, I'm always happy to rely on Arq which should be one of the top ten installs on any Mac.

I have been using Transmit to backup all my critical data to Amazon S3 2 or 3 times a week and to be honest it is a real pain. I tag all my files that I want to backup with a keyword and label to make them easier to find but it still takes a considerable amount of time to backup my files. And when you get busy it is easy to talk yourself into waiting another day or skipping the backup all together. When I first tried Arq I was impressed with the Amazon S3 features. Arq is simple to use, you just pick the folders you want to backup and Arq does the rest. What is really nice about Arq is you can use the reduced redundancy which is cheaper or you tell Arq how much you want to spend backing up your data each month and when you reach your storage limit Arq will delete the oldest of the files. Arq works very similar to Time Machine in that it keeps multiple backups until you run out of storage. However, the user sets how much storage he needs or how much he wants to pay and Arq takes care of the rest. I highly recommend this application. As a mater of fact I have added it to my favorites list of applications that I install immediately on a new machine or clean install along with Launchbar, Keyboard Maestro & 1Password.

Version 2 is excellent. I appreciate how the developer solicited opinions from beta testers, fixed bugs immediately, and put out an excellent upgraded version. Arq provides peace of mind for 30 bucks, and Amazon's pricing for backup is most affordable as well.

Peace of mind, the most affordable way possible. I wanted to make sure all of our family photos and other irreplaceable files were backed up off-site, and Arq is the perfect solution. Since it's based on Amazon's S3 service, you pay for only the storage you need. Much better than paying a flat rate to some backup company, and either overpaying for what you use or underpaying- and wondering how long they'll be around. Arq is designed for the Mac, so it runs quickly and efficiently, preserving absolutely everything some cross-platform applications miss. Well done.

I downloaded Arq and was very interested in trying it out. Unfortunately I was unaware that Amazon S3 required a credit card for a supposedly free account. It's too bad that Arq is limited to using Amazon's service because I've read nothing but great things about it.

This software is GREAT. It has extremely low resource usage, it is very reliable for backup/restore, and it is very easy to use. It also uses Amazon's S3 for storage and makes it very easy to transfer files between computers (back up from one, restore to another). I have nothing but great things to say about it. The price can end up being a bit higher than alternatives because you have to pay for your S3 storage usage, so if you have 100 GB of data you're backing up, it will be around $10/month you pay to Amazon. Still, for me, it's worth it, as I can see the backed up data and access it via any tool (e.g. Transmit or Jungle Disk) that can access S3. It's encrypted in a way that I can't pull it OUT through those tools (easily), but I can verify it's there. Developer is extremely responsive. This is truly a 5 star app. And I'd RATE it as such if the MacUpdate GUI didn't capture my click at 4.5 stars and stick there >:-(

Excellent software that 'just works'. I use Arq to back up a handful of critical folders as a supplement to the full backups that I do nightly to an external disk. I recently had to recover a big database, and found it easier and faster to restore it with Arq - I just opened the latest backup in the Arq window, dragged the file to the Finder, and Arq copied it back from Amazon S3. It was so painless that I was almost in shock. Arq paid for itself right then and there.

Very easy to setup and run. After a long search for that kind of software (Mozy, Wuala, Dropbox and many others), finally I discovered Arq! There is really nothing to complain about this software, so I give it 5 stars. It fulfills all my wishes of backing up online (security, user friendliness, price, CPU usage, configurations and so on ) ... Thank you developer!

Hopefully, if the worst happened and your Mac disappeared, you'd be able to rely on your cloned backup (which you do everyday right?), restore it to your new Mac and be up and running. So, in these circumstances, what would happen with the Arq backups from the previous Mac in terms of syncing them with the new Mac? Its a question I asked the developer and within minutes, he came back with the answer I was hoping for - that, in this situation, the restored Mac can sync with your previous online backups straight away. No reloading your data all over again for weeks/ months on end just because you have a new Mac - another example of how this is superior software.

If you try most of the online backup services, it will become apparent that the best top two applications are this one and Backblaze. Both are simple to operate, work efficiently in the background, appear faster than the alternatives, enable archiving of changed/ deleted files and do not hog system resources. Both developers are very quick to respond to enquiries too. It's after this that Arq begins to leave Backblaze behind, producing copied file metadata identical to that which has been backed up, more flexibility with archiving and the knowledge that your backups are kept more securely and redundantly with Amazon amongst many facilities, not primarily in just one central storage premises (luckily, the Backblaze technicians were smart enough to ensure there was no data lost after their power outage in April this year). If you are backing up, say 70/80g of mostly photos, music and documents like me, the difference in monthly cost will be $2 to $3 dearer with Arq, but that's the difference between a very good product and the best. In summary, Arq, used in conjunction with your favoured local backup/ cloning tool is currently the best quality backup there is.

Completely awesome. This is the correct way to back up data on the Mac. The only reason to use something else is if you can't afford to back up to Amazon S3. In which case, well, you;ll have to spend a lot more time dealing with your backup system, no matter what software you use. As an aside, I once restored my home directory using CrashPLAN. It took TWO DAYS to restore my 60GB home dir, even though the backup storage was on my gigabit LAN. When it was done, thousands of modification dates had been reset to the current date, and other file metadata was lost. Arq is MUCH faster, even restoring from Amazon, and it is one of the only Mac backup apps that does not subtly corrupt your files by losing metadata and dates.

I would agree with the comments made previously. The software is first rate, easy to use and does what it says on the website. Speaking of which i would recommend to people to visit the developers website. The detail which they have gone into to ensure that their backup software is effective is incredible, it is not just hype because they publish their methodology so ( if needed their tests could be reproducible). Also, i ran into a few problems whist restoring a large batch of photos ( > 1gb ), Arq crashed on several occasions. But was able to restore my files by downloading in smaller batches (about 250mb). After each crash, Arq displayed a pop-up asking if i wanted to send a report. which i duly did. What i am finally getting around to saying, is that one day later a fix is published. Now that is what i call service. My faith in the software is rapidly increasing. Thank you for saving my butt, if i had lost the wife's pictures.........!!

I concur with the previous reviewers. In my experience, Arq has been the best backup solution for me in terms of ease of use, intuitive interface, and reliability. I had been looking at other possible solutions for backing up to Amazon S3 servers and Arq was by far the finest for my needs and preferences. Although there isn't much to do to get up and running, Arq does allow users to set preferences accordingly. For example, network preferences can be set to "maximum," "automatic," or "fixed (by user)" transfer rates. Another great feature included in Arq is a "Budget" setting, which ensures you don't go over a monthly rate for storage (not bandwidth, however, which is free until June 2010). Just enter your monthly budget and Arq will indicate how many gigs you'll be able to store at that price. As the developer Stefan points out, Arq is like Time Machine for remote backups. That's an apt analogy and an efficient way of doing backups of your most important files. Although the price point is slightly higher than other products out there, the product is top notch and using AWS you'll end up saving money on storage over time. Highly recommended.

I've been VERY pleased with Arq. I needed a solution that worked with S3, and Jungle Disk just didn't cut it. Arq has a very streamlined interface and really nails the "set it and forget it" requirement. Most of all, I'm confident in the backups. I've done a couple restores just to test, and all my meta data made it back. This is a HUGE requirement for me since I still have a lot of AppleScripts and older data files with resource forks, which other backup programs step all over or ignore altogether. Following the developers blog a little big, I can see the care and effort he has put into making Arq a solid backup solution. While the price is on the high end of the backup solution range, it's still competitive, especially given how care free my use has been so far.

Absolutely terrific software. Backs up flawlessly each time, restoring is easy too. Price is a bit high, but given that there aren't any other automatic S3 backup programs (other than JungleDisk) and given that Arq has such a nice, simple, and easy to use interface I'm inclined to overlook it that minor complaint.
