DAR (like tar but with granular checksums for easier recovery from corruption)
Actually par2 provides that feature. What dar gives you is multi-storage-medium support via running arbitrary scripts to change medium. tar has nothing like it.
works very well as long as you don't have very large files that change frequently
Like, uh, VM images? I hear they're quite common these days.
(If you've got a lot of those, try rdiff-backup. It's slower than rsnapshot, but when a file changes it stores rdiff-format compressed deltas from the new file to the old one, rather than resaving the entire old file all over again.)
