We are using also TSM for file-based backup. This, however, is used only 
to restore old versions of single files, not in case of broken 
filesystems. With today's huge /vicep-partitions we use RO-volumes on 
separate servers as backup solution. These RO-volumes can be converted 
to RW-volumes within few minutes.
