I like dirvish. The only reason (AFAIR) I chose rdiff-backup is that
rd-b uses compressed deltas, which can save a lot of space when you
have large files that change only a little bit. Both use rsync (gotta
have it for my WAN links). But dirvish uses more space. If you stored
dirvish on a compressed file system, though, that rd-b advantage might
go away.
