My reason for setting "Max Volume jobs=1" is that migrations will not occur
unless a tape is marked full, used, or error. To shorten the backup window, I
back up to striped SSDs, and from there migrate onto tape. Setting max jobs to
1 ensures that last disk volume is marked "used", rather than "append". I
couldn't think of an easier way to do this than setting max jobs to 1; what is
the preferred way to do it?
My pool definition is:
Pool {
Name = tempDisk-pool
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 5 days # We want to recycle this thing next
week
Maximum Volume Bytes = 100G
Maximum Volumes = 20 # not all of them have to be full
sized??
Maximum Volume Jobs = 1 # migrations will not occur unless
volume marked full,used,error.
# append won't migrate to prevent
attempts to read & write simultaneously
# last volume in set will be 'append',
unless it's only allowed one job
Volume Use Duration = 23 hours
Recycle Oldest Volume = yes # This one respects retention times
Label Format = "tempDisk-"
Action on Purge = Truncate
Storage = File1
Next Pool = weeklyMain-LTO5-pool
}
Thanks for looking at this,

Please include your Pool definition. It looks as though you have
misunderstood and misconfigured something, but without seeing your
configuration we can only make guesses as to what.
That said, "Max Volume jobs=1" is USUALLY a bad idea unless you have
specific reasons for doing it that way.
