rsync encrypted backups

Discriminant · 2010-12-02 05:54:59

I want to use rsync as my backing up tool, copying/rsyncing my work directory to an external HD. Is there anything like an encrypted partition for this HD that will require a password before mounting? I need to ensure that only I can access this without sacrificing the performance of rsync.

Encryption adds overhead. You can't avoid it. Try TrueCrypt for encryption on the external hard drive.

Another solution is to use ENCFS.

Plus if your source dir is also crypted with it, you are able to rsync without crypt/decrypt overhead (because encfs store encrypted files on disk, no partition needed).

LUKS can encrypt the whole partition, requiring a passphrase before mounting.

That's an interesting idea.

I use LUKS for my backup drives. Works well for me.

luks here aswell. the encryption adds some cpu overhead (unless you have hardware to do encryption natively, like the via padlock), but this is usually <5% with a decent cpu, and since your bottleneck will be disk speed (or network if you use 100Mbps ethernet) the cpu overhead causes no impact on the backup speed.

+1 luks. Using for 6 months on all of my partitions (system _and_ backup) without any issue.
