 * There are two operations that come under the general area of
 * backups.  'Archiving' occurs 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.
