I have a backup containing folders for daily snapshots. To save space, identical files in different snapshots are deduplicated via hard links (generated by rsync).
When I'm running out of space, one option is to delete older snapshots. But because of the hard links, it is hard to figure out how much space I would gain by deleting a given snapshot.
One option I can think of would be to use du -s first on all snapshot folders, then on all but the one I might delete, and the difference would give me the expected gained space. However, that's quite cumbersome and would have to be repeated when I'm trying to find a suitable snapshot for deletion.
Is there an easier way?
