vgcfgbackup

Back up volume group configuration metadata to files (not user data). More information: https://manned.org/vgcfgbackup.

• Back up metadata for all volume groups (to /etc/lvm/backup/ by default):

vgcfgbackup

• Back up metadata for a specific volume group:

vgcfgbackup {{vg_name}}

• Write the backup to a specific file:

vgcfgbackup {{[-f|--file]}} {{path/to/backup}} {{vg_name}}

• Back up multiple VGs using a filename template (%s becomes the VG name):

vgcfgbackup {{[-f|--file]}} {{/tmp/vg-backup-%s}} {{vg1 vg2 ...}}

• Increase verbosity (repeat -v for more detail):

vgcfgbackup {{[-v|--verbose]}} {{vg_name}}
