NAMEvgcfgbackup - backup volume group descriptor area
SYNOPSISvgcfgbackup [-d|--debug] [-f|--file filename] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose] [VolumeGroupName...]
DESCRIPTIONvgcfgbackup 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.
OPTIONSSee lvm for common options.
