> We have a WSS 3 farm that has two WFE's. We use DocAve for backups. For some

> 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
> --

> I thought I could get all the system timer jobs to launch using
