Package: backup-manager
Version: 0.5.7-1
Severity: wishlist

Some of my system directories remain unchanged for long periods of time,
so subsequent backup tarballs are byte-for-byte identical.  Would it be
possible to eliminate such duplicates?

At the very least, replace them with hardlinks.  A more advanced scheme
might detect a duplication and replace the older of two matching files
with a softlink to the newer one, so that e.g. CD backups could benefit
from the same elimination of duplicates.

(Note that always replacing the _older_ of the identical files with a
link reduces the risk of accidentally deleting the archive and then
being stuck with dangling links instead of a backup)
