Backup Central

I sent a post a couple of days ago about this, but haven't seen any response.
One of my critical machines is backed up using a cron job (same one works for
many other machines).. this machine always logs this message:

2004-07-29 02:00:01 User backuppc requested backup of www.instihire.com, but one
is currently running

I have verified that there is none running, and looking at host status, you see
that it's not getting backed up.

What can I check here?

I believe if I remove pc/www.instihire.com/LOCK the backup will run tonight, but
I don't want to have to remember to do it every day.. and a cron job is just a
bad idea.. unless the job can check if a backup is actually in progress.

TIA

Why aren't you scheduling the backups through BackupPC's configuration
files? There should be no need to schedule backups through cron, at
least that I can think of.

On a similar note, I did an archive for the first time today, and only
after I had started it I realized I wanted gzip and not bzip2
compression. I clicked the 'stop/dequeue archive' button, and it
stopped the job and the archive host's status page didn't list any
running jobs, but the main status page still listed the archive job as
running and it wouldn't let me start a new archive job. I had to stop
and restart the backuppc service to fix this.

Removing pc/www.instihire.com/LOCK should not make any difference.

This is strange. Even with $Conf{FullPeriod} = -1, BackupPC still
queues BackupPC_dump, although it does nothing. Is 2am a regular
wakeup time for BackupPC? Maybe there is a race condition: your cron
job queues the request just as BackupPC is running BackupPC_dump.
Sounds unlikely, but worth checking.

If so, just shift the cron time by a few minutes.

Actually, this machine has a DB on it, and it get's dumped to the file system at
2am. I want to ensure the BackupPC backup of the system runs AFTER the DB
Dump.

The backup was indeed scheduled at 2am, and 2am was a wakeup time for BackupPC.
I shifted the cron job to 2:10am and I believe this will indeed fix the
problem. I have several other servers that I backup similarily, and I had
"subconciously" set them to run at times other than X:00. No problems with
those.

I will report the results next weeks.

I can't find Craig's reply to reply to.. so I'm replying to my original post so
everyone will have the information.

I changed the cron scheduling of my backup such that it didn't coincide with a
BackupPC Scheduled wakeup and that seems to have cleared up all the problems.
