Im looking for software that can do incremental remote backup of only some files (like documents, some pictures and so on which I can store in a spesific folder) for windows and linux computers. Also the files should be encrypted before they is sent to my backupserver.

The "solution" I have right now for this is using rsync, but It dosen't offer ecryption of the files as far as I know (they should be stored encrypted on the backup-server), only encrypted transfering.

Point me if im wrong.

Im not sure what the best practice for this is so it would be nice with some tips.

Thanks

you can tunnel rsync over ssh fairly easily... job done! you may also wish to use preshared keys and such (i.e. totally standard ssh stuff) to avoid passwords etc... http://sial.org/howto/rsync/

Hmm. Maybe I explained myself not good enough (sorry). Or do you mean that rsync also stores the files encrypted?

I need them to be stored encrypted so I not can watch others files. And of corse the person who owns the files should be able to decrypt the data too!

Maybe you need some more sophisticated backup software, supporting data encryption like Bacula.

yeah it's rsyncs job to make two places the same, not to backup per se. that said there's still options. if could easily divide and conquer and use a cryptfs volume to perform the encryptions on generic data stored to disk. here's a similar exmaple of rsyncs to a cryptfs filesystem:

about half way down the page. you cuold probably use a loopbakc to have it held within a single file too, but this is really only if you wish to enhance the existing rsync side of things, and an alternative reimplementation may be more suitable.

Amanda can handle that as well.

It all depends on what your setup and objectives are. You can specify directories or subdirectories to backup and you can exclude things using a pattern, so there is a fair bit of flexibility in defining what you want backed up. Then you can compress it, encrypt it, transfer it through ssh but leave it unencrypted at the end, etc. You can also have it go to a disk as a virtual tape, to a tape, etc. And it doesn't require the extra overhead of an SQL database or have several daemons running all the time.

On the other hand, if you just have a few computers with a few directories you want synced, then it may be overkill.

Also, regardless of how you do it, don't ever lose your encryption key. ;-)
