Problem with bup (until recently) is that the nature of its git-based
approach prohibits you from ever removing anything from the backup.

"Unti recently" because there now is a way to do data retention, but:
"bup only has experimental support for pruning old backups."

While bup is a nice program, borg is far more mature at this point.


Sigmentation fault. Core dumped.
