It also provides numerous high-end features like AES-256 encryption, efficient bz2 compression, powerful exclusion rules and scheduler, support for splitting large files during network transfers, network-error recovery, individual digital signature for backed up files, multi-cores machines optimization and much more!
Twin is the best backup solution for Mac OS X users who already have access to online storage (web hosting, work servers, MobileMe...), or who want to buy their own dedicated online storage (Amazon S3, Bingo Disk, Online Storage Solutions), or even users who simply want more control and advanced features than other backup products allow.

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!

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

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.

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.

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!

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.

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.

Easy to configure for both local and remote backups. I like the exclusion system in particular; its files excluded preview is very fast, along with the rest of the program.
