You may also find rdiff-backup to be useful. It can verify data
integrity (although not repair), will preserve permissions and extended
attributes. I like it particularly because the latest backup is a
straightforward mirror, making data recovery trivial. It doesn't,
however, do compression or encryption.

One option for data integrity is to use par2create to make recovery
blocks to store alongside your tar files.
