VGCFGBACKUP(8)						      System Manager's Manual						    VGCFGBACKUP(8)

NAME

       vgcfgbackup - backup volume group descriptor area

SYNOPSIS

       vgcfgbackup [-d|--debug] [-h|--help] [-v|--verbose] [VolumeGroupName...]

DESCRIPTION

       vgcfgbackup  allows you to backup the metadata or Volume Group Descriptor 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/VolumeGroupName.conf.[1-9].old. This enables you to restore your volume group configuration	up
       to 10 steps back in the backup history.

   OPTIONS
       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -v, --verbose
	      Gives verbose runtime information about vgcfgbackup's activities.

DIAGNOSTICS

       vgcfgbackup returns an exit code of 0 for success and > 0 for error:
