That's not a problem, although for your setup I would recommend something
much larger... when the spool space is smaller than the data you need to
backup, bacula first fills the spool space, writes that to tape, and
continues reading from the clients and spooling. No problem, only it doesn't
speed up the single backup, but with slow clients that prevents excessive
shoe-shining.
The big advantages of spooling are:
1: It speeds up incremental backups
2: It allows multiple simultaneous backups to run efficiently.
That's one big issue with todays tape drive :-)
In a production system, I'd recommend a seriously fast RAID subsystem
dedicated to spool space only...
Spool data is transient and losing it isn't a big issue. Striping (raid 0)
of temporary space is a much bigger win than any form of RAID unless you
have a _very_ fast hardware controller.
