NAME
       vgcfgbackup - backup volume group descriptor area

SYNOPSIS
       vgcfgbackup   [-d|--debug]   [-h|--help]  [-v|--verbose]  [VolumeGroup-
       Name...]

DESCRIPTION
       vgcfgbackup allows you to backup the metadata or Volume Group  Descrip-
       tor  Area  (VGDA) of one to all volume groups to files in /etc/lvmconf.
       If you don't give any volume groups in the command line,  all  of  them
       will  be  backed  up.   This DOESN'T backup user/system data in logical
       volume(s)!  To restore volume group descriptor  area  backups  see  the
       vgcfgrestore(8)  tool.   A  10  step  history is backed up in /etc/lvm-
       conf/VolumeGroupName.conf        and          /etc/lvmconf/VolumeGroup-
       Name.conf.[1-9].old. This enables you to restore your volume group con-
       figuration up to 10 steps back in the backup history.
