Backup Exec 2010 R3 backups taking days to complete

We have Backup Exec 2010 R3 running on  Server 2008 R2.  When I do full backups on Exchange it can take two days or longer to complete the backup.  I have cleaned up the old exchange mailboxes and permanantly deleted the disconnected mailboxes, we have plenty of space on the backup drives.  We are doing backup to drive, not tape or other media.  This is really becoming a problem as the backups are continually running and it throws off my incremental backups.  Thank in advance.

Did you notice backups being stuck at preprocessing or at any other stage for hours; if you do try unchecking the consistency check from the backup jobs and rerun the backup.

Try uninstalling and reinstalling remote agent at the exchange server, in some cases outdated agent has been found to be causing the issue.

If its not getting stuck then try isolating the issue, try taking backup to local disk or external disk and compare the speeds

it is not being stuck during the preprocessing stage.  It is in the running stage and at this point running at 114 mb per second.  We are doing online backups, so people are using Exchange but I thought that was one of the advantages of the new Exchange.  I will remove the consistency check on the job and try to re-run it.  I will also re-install the remote agent, which I haven't done in awhile.   We have other jobs that are completeing backing up to the same disks, but I can try to find another source to save to to see if the speeds improve.

Perfect I think these steps should take care of the issue in one or another way, if any issues kindly post back.

Good Luck.

So you are backing files on one partition to another partition on the same drives?

Hi Jeremydehner,

Since you mentioned you're backing up to EMC storage, have you checked to see there isn't a failed battery component, or any other failed component for that matter, on the storage device?  

Depending on what EMC storage platform you're using, the cache battery or UPS attached battery is crucial to the performance of the storage platform overall.

In the past when the battery/UPS fails on the EMC device, performance comes to a crawl.

Hope that helps.

I will check that.  I know that we were having battery issues before.  That is the first time I heard that.  Thanks for the tip.

Jeremydehner,

Just curious, what did you find out to be the cause of your backups being slow?

Thanks!

I took everyone's suggestions into account.  I reinstalled the remote agent, moved the backup time to a more remote time.  I also checked the battery status on the EMC storage.  I also cleaned up the Exchange VM with a  little maintenance.
