Thanks. Oddly enough, pruning of old backups hasn't been a really high priority for me (or apparently any of the other users) because chunking-based deduplication is so efficient that my backup disk hasn't filled up yet :) But it's clear that this will need to be added eventually.

Unfortunately git's normal pruning and gc stuff is inapplicable since it dies horribly when faced with hundreds of gigabytes of data. That's to be expected, but it means I can't just cheat by running 'git gc' and hoping for magic.

Have fun,
Avery
