 * There are two operations that come under the

 * just before a volume group configuration is
 * changed.  The user may configure when archived
 * files are expired.  Typically archives will be
 * stored in /etc/lvm/archive.
 *
 * A 'backup' is a redundant copy of the *current*
 * volume group configuration.  As such it should
 * be taken just after the volume group is
 * changed.  Only 1 backup file will exist.
 * Typically backups will be stored in
 * /etc/lvm/backups.
