xTwin isn't $19. On the adnX website and on the App Store it's listed at $99.06, quite a bit more (and a deal breaker for me...).

Hi Warren,
You're welcome! :)
Maybe they'd be interested in a MUPromo??? ;-)

Have to change my review today: 1.5 crashes. Asked the developer to send me an old version: They told me they "do not keep old versions". Well, well. This does not help if you end up with a non-functioning 1.5.1...

Probably the worst application i ever bought. Ever since first version it randomly shuts down and doesnt backup anymore. I had to keep an eye on the menu to see if it was still there.

Kept posting my issues on the developers forum but they kept deleting my posts, saying "there are currently no issues with current realease". Every single negative post, they deleted after a couple of minutes. I couldnt get any support at all. Tried getting my money back to no use.

Bad software, even worse developer. Stay away!

Issues cannot be posted to the forums, only to the technical support website. Sorry but it's not true that we do not solve issues reported by customers. See other customers comments. We care about all feedback.

Frenzy, sounds a little weird. I use the software since months with no problems. Even with local encryption and incremential backups to WebDAV servers. Do you ever consider your machine being the culprit? Did you ever try the application with another computer?

And no, I do not work for app4mac. Still, I like the product - even more if it would be $30 instead of $60 :)

I tried this out for the Amazon S3 backup. It just doesn't work. It fails after a few seconds. I manually retry and it works for another few seconds. I was hoping to switch from Interarchy 9 to this but it looks like I'm upgrading to Interarchy 10.

Strange as most customers are using it with Amazon S3. Send your feedback to the support team instead of complaining here. We always fix all issues.

The price is now euro 99 ($130 as of today). This is much too steep in my opinion because you also have to pay for the storage space. You could get almost three years of BackBlaze with unlimited data instead, and buy something else with the money you were going to spend on the storage.

That said, this app works pretty well with one significant major limitation: It only keeps one version of the data (even the MobileMe Apple Backup program will keep 30 days or so). I don't understand why this limit is built into Twin, because it's my storage space, so I should be allowed to clutter it up with old versions.

This seems to be the only application that can back up to MobileMe using encryption and incremental uploads. It's easy to use too (unlike Super Flexible File Sync) and is pretty stable (again, unlike Super Flexible File Sync). However, it's much, much too expensive for what it does.

All updates are free for lifetime. Divide the price by the numbers of years you will use it with free updates and you will understand the price.

I'm running the latest version of Twin 1.2.1 and a lot of the old issues present in the older reviews appear to be resolved. Its quite stable and can cope with occasional loss of network connection, continuing where it left off (very useful for backups over 40 Gb). The reports are quite verbose if there are errors and it usually just requires a click of a button to redo failures.

Twin has a very good, very intuitive interface that offers AES-256 encryption on the fly. On Restoration its handy to have a listing to restore just individual files. The developers seem to be actively improving the software regularly over the last few months.

I thought this program looked very promising and I really wanted to like it. Unfortunately I couldn't get it to work on my Mac to backup on a server over the internet. Despite multiple attempts of contacting the support team via support forum and emails I wasn't able to get a single helpful response within the last 6 weeks (!). So I paid good money for this program, haven't managed to back up a single file yet and am getting more and more annoyed with them. I tried to get my money refunded - also unsuccessfully.
Bottom line: Unfortunately this is not a program on which you can rely on for backups and the service and support they offer is absolutely appalling. Nice idea but nothing for serious use!

In theory, this is a great app. In reality, not so much. With each new upgrade something breaks (all updates made me forced to delete all backups and start over from scratch). Developers does not listen to feedback and keeps deleting threads about issues, stating "theres no issues what so ever" and "no users are having problems". Clearly they do not want any relations with the people buying their software. Theres no real added features in new versions and the software works almost exactly the way it did when THEY bought it.
Its all really a shame, because this could have been SO good, its a backup app that does its job great in the background, until it breaks/hangs and youre left out in the cold. For 49€, the very least you could expect is a friendly developer.

I use Twin to back up about 40 GB of data to Amazon Web Services.

Pros:

Data persistence. Amazon won't go out of business suddenly, taking your data with it. You don't need Twin to retrieve the data. If the developer disappears or the app stops working, you can still get to your backups with third-party tools.

Data privacy. Data is encrypted with the standard AES algorithm before being transmitted. You can decrypt the archives with open-source tools.

Stability. No crashes in several months of using this app.

Flexible scheduling. You can set Twin to back up periodically and/or when the network becomes available -- useful for portables that aren't always connected.

Cons:

Inefficient use of bandwidth. Data is packaged in archives of fixed size, which is decided at setup and can't afterwards be changed. The default is 1 MB. So if you change a single byte in a small file, at least that amount of data has to be sent. If you change a single byte in a large file, the whole file has to be sent. It would be better if Twin used something like librsync to back up only the parts of files that have changed.

Mirror backups only. The backup contains the most recent version of each file you've selected. There's no option for incremental backup.

No obvious warning of failure. The interface is normally hidden. The only indication of a failed or incomplete backup is in the interface. If you don't look for it, you won't see it.

Suggestion:

Offsite backup is a last resort in case of total destruction of your primary site, including your local backups. Put all the data you need to recover your backups on a small USB flash drive (encrypted, of course) and keep it with you at all times. That would include, at a minimum, your AWS public and secret access codes, your backup encryption keys, and your Twin registration data.
