Amanda can easily use removable hard disk as virtual tapes, the user only needs to mount/umount the hard disk.
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.

* Mount (MOUNT) the disk if it is not already mounted. The system must be configured to allow the amanda user to do it.
= Assigning meta label to already labelled volumes =
* Umount (UMOUNT) the disk when the program exit.
If you already use removable hard disk, these disk don't have a meta label, you can easily assign a meta label to each label with the amlabel command
* Amanda needs a lock file (UMOUNT-LOCKFILE) to do safe umount.
  amlabel <conf> <label> --meta <meta-label> --assign
* Umount the disk after (UMOUNT-DELAY) second(s) when the disk is not in use. A value of '0' leads to unnecessary umount/mount.
You must assign the same meta label to all label on the same removable hard disk.

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"
 }
