Meta label
This feature is available from Amanda 3.3
A meta volume is a container for many volumes. A meta label is the label of a meta volume. Use amlabel to create meta label.
A meta volume can be use if volumes are always loaded/unloaded at the same time such as Removable hard disk changers.
Changer chg-disk is the only changer that can handle meta volumes. The amanda.conf parameter meta-autolabel can only be used with chg-disk.
Assigning meta label to already labelled volumes
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
amlabel <conf> <label> --meta <meta-label> --assign
You must assign the same meta label to all labels on the same removable hard disk.
