Because a Job requires a FileSet. :)
I use this FileSet for such jobs:
FileSet {
Name = "EmptyCopyToTape"
}
and I use it like this:
Job {
Name = "CopyToTape-Inc"
Type = Copy
Level = Incremental
Pool = IncrFile
FileSet = "EmptyCopyToTape"
Client = kraken-fd
Schedule = "CopyToTape-Inc"
Storage = DigitalTapeLibrary
Messages = Standard
# don't spool date when backing up to tape from local disk
Spool Data = no
Spool Attributes = yes
RunAfterJob = "/home/dan/bin/dlt-stats-kraken"
# no sense spooling local data
Spool Data = no
Spool Attributes = yes
Maximum Concurrent Jobs = 40
Priority = 410
Selection Type = SQL Query
Selection Pattern = "
SELECT DISTINCT J.JobId, J.StartTime
FROM Job J, Pool P
WHERE P.Name = 'IncrFile'
AND P.PoolId = J.PoolId
AND J.Type = 'B'
AND J.JobStatus IN ('T','W')
AND J.jobBytes > 0
AND J.JobId NOT IN
(SELECT PriorJobId
FROM Job
WHERE Type IN ('B','C')
AND Job.JobStatus IN ('T','W')
AND PriorJobId != 0)
ORDER BY J.StartTime
"
}

Yes, the FileSet defined in the Copy Job does not necessarily have to
match
the FileSet in the job[s] it will copy.

Done. See above.
What you may want more help with is the selection process. The
'Selection Type'
I use above will copy waiting Jobs in the IncrFile pool and copy them.
Where does
it copy them? To the Incremental pool, which is a tape pool. This
aspect is defined
in the IncrFile pool:
Pool {
Name = IncrFile
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 3 weeks
Storage = MegaFile
Next Pool = Incrementals
Maximum Volume Bytes = 5G
LabelFormat = "IncrAuto-"
}
I wrote up two posts while I was setting up my copy jobs. I hope they
are useful to you:

Hope that helps.
