Restore is done at media-set granularity, so you first need to find
out which media set contains the data you want to restore. This
information is stored in the media catalog. If you do not have media
catalogs, you need to restore them first. Please note that you need
the catalog to find your data, but restoring a complete media-set does
not need media catalogs.
The following command shows the media content (from catalog)::
# proxmox-tape media content
