[BackupPC-users] BackupPC backups slowing
2010-10-13 15:42:05
Apologies in advance, as I am rather a newb to this system. I have been running
BackupPC for a few months now backing up approximately 20TB raw across 30
machines - but I am NOW noticing almost no throughput of jobs kicking off,
unlike when I first started the system.
I suspect it has something to do with concurrent jobs running. I had been
playing with "MaxBackups" (setting at 22 currently)...well, actually here are
all the settings:
Concurrent Jobs
----------
MaxBackups = 22
MaxUserBackups = 4
MaxPendingCmds = 10
MaxBackupPCNightlyJobs = 2
BackupPCNightlyPeriod = 1
But only one thing is running out of the scheduler today (and for a while).
I notice in the "Queue Summary" page that the Background Queue Summary is around
40 jobs - ranging back up to 10 days old. But even worse is the "Command Queue
Summary"...which has BackupPC_nightly jobs going back a month.

admin1 10/11 01:00 BackupPC BackupPC_nightly 128 255
admin 9/13 01:00 BackupPC BackupPC_nightly -m 0 127
admin1 10/3 01:00 BackupPC BackupPC_nightly 128 255
admin 10/10 01:00 BackupPC BackupPC_nightly -m 0 127
</snip>
There are plenty of horsies left on this box - so I crank some throttles here.
But which one do I have to turn up?
I see that _nightly is supposed to be able to run concurrently with backups -
and I could turn turn up $Conf{MaxBackupPCNightlyJobs} = 2; ...but it seems that
isn't suppose to interfere with $Conf{MaxBackups} = 22 - right?
Sorry to be so dense.
