I use exchange 2007 SP2, and experienced backup and online maintenance job conflict several times. Even after I separated backup job and maintenance job running in totally different time.

In event log I found after event 1221 said how many spaces have been released by maintenance job, at the end of the online maintenance time window, event 1100 occurs several times again in next hours, said how many folder has been deleted. It looks very odd because I think after online maintenance job finished there shouldn’t have any database cleanup action followed.

I have only one mail storage database and one public folder. I also find there is a maintenance overlap warning at the end of the online maintnenance job. How can I find out what bring another maintnenance job? any idea or instruction will be appreciated.

check the maintenance schedule on the properties of the mailbox store, what schedule is it set to? The online maintenance will run between 00:00 and 05:00 normall, what time is your backup scheduled for?

Demazter, thanks for your quick feedback. I have changed my maintenance job running time to day time, which is 2:00 PM to 5:00 PM. and I am very sure that backup already finished in middle night at about 2:00 am. I even double confirmed the maintenance job running time window by EMC and EMS, seems there is no overlap at all.
The problem is after 5:00 PM, even after 6:00PM, there is still maintenance action. which will bring confilct with following backup action.

If the maintenance starts at 5:00 it could potentially still be running.  I would recommend that you set the maintenance back to 01:00am to 05:00am and make sure the backup runs BEFORE the maintenance window.

No , maintenance starts at 2:00 pm. it suppose to finished at 5:00 pm, as I set in the EMC.
I wouldn't put backup runs before maintenance because backup finished time is various. some time it takes very long time.
You mean, even after 5:00 pm, maintenance will keep in activation in backgroud?

the maintenance could still be running.

You should always backup before the maintenance is run, if the maintenance deletes something you need it then it's gone for good unless you backed it up.
