Here is the example of the bsr file format I have used in the past
(in this example a job spreads through two volumes):

Volume = volume-0003
VolSessionId = 592
VolSessionTime = 1435614003
Volume = volume-0004
VolSessionId = 592
VolSessionTime = 1435614003


The above example was created from the output of bls -j <volume>
VolSessionId in the above example is the same as the SessId in
the bls output and VolSessionTime in the above example is the
same as the SessTime in the bls output.

That should be enough to get the specific job restored using the
bextract tool but I tested it only with file storage where volumes
are files on the disk and not the actual tapes.
However, I believe that there shouldn't be much difference in this
case.
