No. You can override the job level, storage, pool, and message resources
to use, but not the spooling.
However, despooling at the end of a job deletes any spool files written
to a volume, therefore frees space as soon as the job finishes. There's
not much reason to turn it off for incremental jobs only, since they
generally run daily and are small. With small spool files from daily
incrementals, it won't really slow the jobs down that much, just the
time needed to write the spool file to the volume file on disk. If
incrementals are known to be huge, then you could write incrementals to
tape too. Ultimately, I think you either need more tapes or more disk
space, but the data has to go somewhere.
Otherwise, if you have suitable disk space, you could write your full
and diff backups to disk, then copy or migrate them off to tape. Spool
data would be set off for the disk jobs, and set on for the
copy/migrate jobs. Migrate would be the strategy that frees disk space
as soon as possible, if you have enough disk to hold one round of
fulls, but not enough for all the fulls in your catalog.

Hi, all.
With my new Bacula 15 deployment, I'm running into something I'd
like to
do, but I don't think there's a feature for it yet. But before I
submit
a feature request, I wanted to sanity check, and see if anyone had an
alternative that I hadn't considered.
Here's the deal. I have jobs that run Full, Differential and
Incremental jobs. The Full and Differential jobs are supposed to
go to
a tape pool, and should use data spooling. The Incremental jobs are
supposed to go to a disk pool, and should not use data spooling. The
job can have "Full Backup Pool", "Differential Backup Pool", etc.,
defined, so different job types can end up in different pools. But
there's no similar job-type-specific "Spool Data" attribute, is there?
Right now, I can handle this by putting in parameters in the
Schedule's
"run" lines. And if those jobs are successful, then great. But if
not
(eg. a Full has failed), then subsequent Incremental jobs might get
upgraded to be a Full. If I have the "Full Backup Pool"
specified, that
upgraded job would (I assume) end up in the right pool, but wouldn't
have the correct spooling set up. Or if I don't have the "Full
Backup
Pool" set, then it will end up in the disk pool, instead of the tape
pool, albeit with the appropriate spool behavior for the disk pool.
I'll put an example of one of my jobs below, so you can tell me
what I
might be missing. Or I can explain again, if this isn't clear.
Thanks,
Lloyd
