I have a similar setup here. I solved it by backing up to disk, then
running a copy job from disk to tape. 3TB are not that many disks as
2TB disks are cheap. May be well worth the hassle and you get faster
every day restore times as well:
- 1 Pool for tapes, called it TapePool here, long retention time
- 1 Pool on disk at least, I do 1 pool per client, NextPool = TapePool
retention time is as short as you need it to be to fit on your disks,
I do 5 weeks
- The Full/differential/Incremental jobs targetting the disk
- after the backup jobs finished, run a copy job to copy the backups to
TapePool, I do it via SQL selection.
Job {
Name = "CopyTape"
JobDefs = "CopyDefaults"
Schedule = "None"
Spool Data = Yes
Spool Attributes = Yes
Priority = 8
Pool = DiskPool
Selection Type = SQLQuery
Selection Pattern = "select a.JobId from Job AS a JOIN Pool AS b ON
a.PoolId=b.PoolId AND b.Name!='TapePool' WHERE a.Type='B' AND a.JobID NOT IN
(SELECT PriorJobId FROM Job AS c JOIN Pool AS d ON c.PoolId=d.PoolId AND
d.Name='TapePool') ORDER BY a.StartTime ASC;"
}

I do monthly full, weekly differential, daily incremental. Except
database servers, there it is monthly full and daily differential.
