I think the problem is that if one file in the backup chain
becomes corrupt you can't restore any later backups (not 100%
sure though).

I'm running backups of my computer (about 80GB) and it worked
fine for > 130 incremental backups. But the restore of even a
single file takes a really long time.

As it only happens when Duplicity is interrupted running it
automatically wouldn't help. And if it was interrupted maybe you
want to check the files so automatically deleting them wouldn't
be a good idea.
