Zdenek Kabelac bb45e33518 backup: automatically store data on vg_unlock
Previously there have been necessary explicit call of backup (often
either forgotten or over-used). With this patch the necessity to
store backup is remember at vg_commit and once the VG is unlocked,
the committed metadata are automatically store in backup file.

This may possibly alter some printed messages from command when the
backup is now taken later.
