  24  * There are two operations that come under the general area of
  25  * backups.  'Archiving' occurs just before a volume group
  26  * configuration is changed.  The user may configure when
  27  * archived files are expired.  Typically archives will be stored
  28  * in /etc/lvm/archive.
  29  *
  30  * A 'backup' is a redundant copy of the *current* volume group
  31  * configuration.  As such it should be taken just after the
  32  * volume group is changed.  Only 1 backup file will exist.
  33  * Typically backups will be stored in /etc/lvm/backups.
