vgcfgbackup allows you to backup the metadata of your volume groups.
If you don't name any volume groups on the command line, all of them
will be backed up.
In a default installation, each volume group gets backed up into a
separate file bearing the name of the volume group in the directory
/etc/lvm/backup. You can write the backup to an alternative file
using -f. In this case if you are backing up more than one volume
group the filename is treated as a template, and %s gets replaced by
the volume group name.
NB. This DOESN'T backup user/system data in logical volume(s)!
Backup /etc/lvm regularly too.
