Hi!

I just got thinking about backup levels. Our monthly full backup ran
longer than usual, an meanwhile the next incremental one got started.
The last job of each backup is the bacula catalog, with a priority
of 50, as suggested in the example config. Now the catalog job from
the full backup (pool monthly) is waiting on the newly scheduled
incremental jobs (pool daily)...
I could run the catalog at the same priority as the other jobs, but
then it probably wouldn't come last, because I run more than one job
in parallel.
Wouldn't it make sense to prioritize first by the backup level, then
by the job priority setting?
Would it be possible not to start a job, if it is already running
with a higher level, resp. cancel a scheduled job if it is not
yet really started and a higher level version gets run? This might
be possible with an external scheduler, but it all depends on things
the director knows anyway, and I prefer not to need external programs.

While I'm at it: I'd like to have another type of retention policy:
prune a differential or incremental job when the higher level job
it depends on expires.
And why not have multiple differential or incremental levels, like
a weekly diff against the monthly full backup and a daily diff
against the weekly one, so that a restore would need only three
tapes (or sets) instead of all those incremental ones?

Just my personal musings - is any of that sensible, or have I gone
off the deep end? Should I put up a feature request?

MfG, Ulrich
