We have a WSS 3 farm that has two WFE's. We use DocAve for backups. Ever
since installing DocAve about a year ago I have been fighting backup
failures for timer job intervals. Here is a representative error:
--
The job failed when backing up the site collection
"http://site1-sharepoint".
The interval between two jobs is longer than change log setting of this web
application.
Current Change Log Setting:90.00:00:00
Current Interval between Two Jobs:103.23:59:54.8959820
Last Job Backup Time:7/16/2009 6:00:46 PM
Current Job Backup Time:10/28/2009 6:00:41 PM
--

What I have been doing is to keep increasing the change log setting, but the
interval between jobs just keeps growing longer. I don't want to keep
increasing the change log setting every time this happens. We started at 10
days and are now at 90.

I have been hunting for information on how to resolve this, but without
concrete results. I have read lots of information about timer jobs, but
nothing to help me find out what jobs are causing this issue.

Can someone point me in the right direction? Is there a way to figure out
which jobs are causing the errors?

Thanks in advance
