The mounted ZFS volumes are datasets. Created by zfs create <Pool>/<Dataset>. 
The current type is filesystem.

I'm not an expert in ZFS - how to set a content type on a dataset ?
 
So the question remains - as these are (ZFS) filesystems, why to Backups are 
allowed to store ?

One part of storage.cfg besides other (zfs) entries:
----------- cut ------------
    zfspool: zfs
        pool Pool/vz
        content rootdir,images
        sparse 0
----------- cut ------------

The GUI does not list other than the above two content types. Could that be a 
bug in the GUI ?

Sure. There are diffent pools.
