=head1 delete-backup.pl

Delete one previous logged backup.

This command removes a Virtualmin backup, which can be identified either using
the C<--id> flag followed by a backup log ID (from the C<list-backup-logs>
command), or C<--dest> followed by a destination path like
C</backups/foo.com.tar.gz>.
