Amanda can back up to removable hard disk changers by treating them as virtual tapes. The user has to load and unload hard disks. Here is the amanda.conf configuration for removable hard disk changers.
autolabel "$m-%%%" any
meta-autolabel "$c-%%%"
define changer removable-disk {
tpchanger "chg-disk:/amanda/diskchanger"
property "NUM-SLOT" "4"
property "AUTO-CREATE-SLOT" "yes"
property "REMOVABLE" "yes"
property "MOUNT" "yes"
property "UMOUNT" "yes"
property "UMOUNT-LOCKFILE" "/etc/amanda/CONF/disk.lock"
property "UMOUNT-DELAY" "1"
}
tpchanger "removable-disk"
- Four slots (NUM-SLOT) are automatically created (AUTO-CREATE-SLOT) on each mounted disk.
- Each slot (autolabel) is labelled with a distinct label.
- The REMOVABLE property requires amanda to check that something is mounted.
- Each hard disk get a meta label. In the future, amanda will be able to ask to mount the disk with the meta label when it require a specific label.
- Mount (MOUNT) the disk if it is not already mounted. The system must be configured to allow the amanda user to do it.
- Umount (UMOUNT) the disk when the program exit.
- Amanda needs a lock file (UMOUNT-LOCKFILE) to do safe umount.
- Umount the disk after (UMOUNT-DELAY) second(s) when the disk is not in use. A value of '0' leads to unnecessary umount/mount.
