Backups of mboxes are a real pain. Append 4k of text, and have to rebackup a 1GB mbox file.
Doesn't rsync --in-place fix that? This option is useful for transferring large files with block-based changes or appended data, and also on systems that are disk bound, not network bound. It can also help keep a copy-on-write filesystem snapshot from diverging the entire contents of a file that only has minor changes.
Maildir allows me to just link that 4k message into the backup, and effectively keep the earlier snapshots without having to purge them out earlier because I've run out of space on my backup regime.
Oh, right, snapshots. In that case I see your point (unless you have a whizzo modern block cow fs).
