First Look: Twin 1.0 for Mac OS X
App4Mac has just announced Twin 1.0 for Mac OS X (US$39.67, €29.00), an online backup solution that works with all sorts of servers: FTP (all varieties), WebDAV, Amazon S3, and even MobileMe. Unlike many of the other online solutions, Twin claims that it retains all the Mac OS X file metadata, ACLs, and privileges, and your data is kept safe with AES-256 "Jack Bauer quality" encryption. In addition to the online backups, you can use Twin for backing up your files to local drives and have the backups begin when the external drive it plugged in.
I'm impressed with the powerful scheduling capabilities of Twin, which include a way to use logical operators to determine exactly when backups should proceed or not. Having an offsite backup is that extra bit of security that every Mac user should have. Check out the gallery below for some screenshots of the app in action. You can also download a free, limited-capability trial of Twin if you're interested in kicking the tires.

Anyone else tried iDrive or Syncplicity?

There is a reason CrashPlan doesn't support these lower intelligence transports and targets. When we designed CrashPlan we decided to not trust the hardware or storage at a backup destination. Each destination automatically verifies your backups autonomously and heals around any errors detected. If you used FTP, you would have to read in all the data over the net to verify it. The larger the data backed up, the more impossible this becomes.
Of course, we could turn off this verification and use a target like FTP, but is it worth it? More bandwidth used, less data security .. seems like an awful lot to sacrifice.
Are you saying that because CrashPlan communicates with other CrashPlan servers, you can do effective data verification on the server side and fetch that result back to the client?
There are other ways to verify data, e.g. you could run your checksum and store the results in a file, which is FTP'd up to the server. So that way, CrashPlan could just pull that file down and compare the checksums.
As far as storage security, that's easy: just add support for SFTP and FTP over SSL.
Anyone know if when backing up via FTP it only sends the delta of a changed file rather than having to re-upload the entire file? I have some crazy large files I modify regularly and it would suck if it had to re-upload the entire files every time.
Guess I could try the demo out and figure it out for myself :P
Very nice app! I was using SmartBackup, but this beats the pants off of it! And the scheduling, bandwidth capping and compression is good!!!! Finally, I can dump all the other backup apps I've tried to send data to my webserver.

About the price, you forgot that all updates are free for your full life, so in fact, it's very cheap with free technical suppport.

Can anyone give me info on the Trial version ? Is it a Limited-time trial (15-day or 30-day) OR a limited function trial with no Time limit ??
Thanks.
Not that impressed. It does incremental backups fine, but when I go to restore an individual file, I can't pick a certain date/revision of that file. And in fact, when I click "Restore...", my Mac just beeps at me. What the heck?
