Linux backup software
OK, so I took a quick look at various backup programs available for linux. This post is neither complete nor completely unbiased, as I already use obnam and am quite satisfied with it. I wanted to re-compare some alternatives anyway, but the other programs didn't even fit my feature requirements.
No deduplication available and you have to rotate the backups yourself.
Citing from bup's website:
'bup restore' can't pull directly from a remote server.
bup currently has no way to prune old backups.
