Not a problem. However, I need to ask a really dumb question. I keep putting
in backup tapes (blank) to copy the jobs but the # of jobs seems to continue to
grow (even though I've not run any additional disk backups). These are daily
incrementals (Mon-Thu) and they expire after 5 days. What happens when they
expire? If they are pruned, does that mean the disk jobs I marked UNCOPIED
again? Thanks for a great product!

Subject: Re: [Bacula-users] Copy job limit is 100?
Hello,
The reason this artificial limit is there is that because I saw several
cases of copy/migrate jobs starting on the order of 600 jobs, which
caused the systems in question to totally choke up. It was probably
a combination of insufficient hardware for 600 jobs, and much too
high limits placed on the maximum number of Storage daemon jobs.
In retrospect, setting it to 100 was probably a bad idea. I am sorry
for the problems you are having.
It is probably better to have a directive or to add additional
documentation that explains the downside of possibly starting
a huge number of jobs at the same time or possibly a different
algorithm. I will find some suitable fix in the next version, which
will be released in March. In the mean time, you can change the
source code to set the limit to a larger value and rebuild from source.
The limit is in file
src/dird/migrate.c
at line 673 and it reads:
int limit = 99; /* limit + 1 is max jobs to start */
Or you can use a special SQL statement as a number of users have
suggested.
Best regards,
Kern

I missed a couple of days (holidays) backing up from disk to tape (we backup
disk to disk every night) so when I went to run the job to copy disk to tape it
only grabbed 100 jobs. This seems sort of artificial (what if I had more than
100 workstations/servers I was backing up?). I was wondering if there is
something to set that will override that setting (I couldn't find one at a
cursory glance). I would prefer not to use a special query if possible (we are
using PoolUncopiedJobs). I know how to write a query and have one already that
I use to see how many jobs need to be backed up. I'm just curious how others
are getting around this artificial limit. Thanks.
I am currently using a custom SQL query to copy jobs. I do this because we have
different backup schedules for various systems. I find the SQL query does give
me more control over what jobs get copied and when.
Unfortunately when I originally configured bacula, I setup the backups for
incremental and full backups for all hosts to be written into a single pool for
disk based backups.
So if I use pooluncopiedjobs I will end up copying all my incremental backups
to tape.
