Git-based backup with bup

Parent article: Git-based backup with bup

rolling checksums are like rsync, so I'm wondering how much space saving this has over rdiff-backup? rdiff-backup does have a "delete older than" option, which I use regularly, and it has become my backup scheme of choice.

Bup's par2-based checking is nice, and I'm a git freak but I think a howto type article that shows all of bup's strengths (with actual commands) would be nice.

Rdiff-backup has a _severe_ flaw in that if the latest part of the backup is corrupted, you lose the whole history.

Noticed that the painful way myself.

Without par2, bup has similar problems. And if you were tempted by the dedup promise and backed up lots of *machines*, they're potentially all gone.

I saw on their mailing list archive that that is why they started par2 support. Nice. But my question was specific to space only.
