/*
|
|
* 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.
