Arq is online backup for the Mac using Amazon S3. It backs up and faithfully restores all the special metadata of Mac files that other products don't, including resource forks, ACLs, and creator codes.
Arq works like Time Machine, except you don't have to remember to plug in your external hard drive. 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
What's New
Version 2.7:
Fixed Bugs
Fixed an issue where changes to extended attributes weren't being backed up if the file data didn't change as well.
Fixed a crash that happens after transient (usually network) errors occur during restoring.
Fixed an issue where unencrypted content-type info was being written to S3.
Other Improvements
Reduced the number of filesystem calls to improve backup performance and reduce load.

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 have experienced exactly what you described in fact, Arq has been re uploading my entire backup again over the last month and on current indications, this process will probably be completed for another month. Whlst this is an issue which is affecting existing users and won't have any effect on new users, it doesn’t make it any less of a pain in the rear. I’m going to stick with it (well, that is unless it happens again), but what this has reaffirmed is that whislt the cloud is great n’all that, Arq and any other form of online backup must only be use as a secondary/ supplementary backup. If you want quick, 100% reliable backup, then the old traditional local backup via usb/ firewire MUST be your starting point.
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.
Great program. Tried do backup manually to Amazon S3 using FTP clients such as Transmit and Flow. Found out it wasn't a good idea. Amazon S3 is not really aimed at consumers. So I found Arq and it takes care of all the Amazon S3 stuff so I don't have to think about it.
Really easy to use also. Just add a folder and it is send to the magic cloud. Hasn't crashed or anything.
The competitors offers "unlimited" online backup for a small fee, I do not really trust them. I hope I can trust Arq the day my computer and local backups get stolen or burn up.
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.
I should follow-up that Haystack software did eventually send out a notification about this problem, albeit almost a month after I posted the original review.
I'm glad that such a major issue has both been officially acknowledged and resolved, but it should have happened faster, IMO.
I continue to use Arq because, developer missteps aside, it really is a great product.
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.
@Michaelgriffith - yes Amazon S3 is indeed available for Australian users. We're based in Sydney and have used S3 for backup for 3 years now. You can choose to use S3 servers in USA or Singapore servers. The pricing is the same - very very cheap per GB from 15cents per GB per month.

Arq lets you set a budget for S3 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 "de-duplicates" your backups, never storing the same file twice in your S3 account.
