3.3. Logical Volume Backup
Metadata backups and archives are automatically created whenever there is a configuration change for a volume group or logical volume, unless this feature is disabled in the
lvm.conffile. By default, the metadata backup is stored in the
/etc/lvm/backupfile and the metadata archives are stored in the
/etc/lvm/archivefile. How long the metadata archives stored in the
/etc/lvm/archivefile are kept and how many archive files are kept is determined by parameters you can set in the
lvm.conffile. A daily system backup should include the contents of the
/etc/lvmdirectory in the backup.
Note that a metadata backup does not back up the user and system data contained in the logical volumes.
You can manually back up the metadata to the
/etc/lvm/backupfile with the
vgcfgbackupcommand. You can restore metadata with the
vgcfgrestorecommands are described in Section 4.3.13, “Backing Up Volume Group Metadata”.
