1. There is no "restore dbbackup" command. There is an operating
system-level operation called "dsmserv restore db".

2. The db backup volume does not *have* to be in the volume history. (It
is easier to perform a restore if it is, but it is not required.)

3. The way that the db backup knows the media format is by having a
device configuration file available to dsmserv that defines the media
format.
