Backup jobs hang when backing up mailboxes

I've noticed that a lot of our backup jobs are taking longer to backup. I am trying to find the bottleneck. I've notice that the exchange mailboxes are taking entirely to long to back up. Has anyone noticed this with their backups.

We have about 60-70 mailboxes that contains pst, pab, etc etc.

I dont know why it is backing up at 1.54MB/min, it will take forever. I am thinking either we need to increase network bandwith, or re-evaluate whats being back up and lighten the load.

This always happens on the full weekend backup. Incs, during the week are fine, of course we're not backing up to much stuff, but the weekends which typically see close to 70GB being backup on the mailboxes is slow.

Check the CA Support Website, I am sure I saw a published solution that addresses backups taking longer than normal, not sure if it applied to MS Exchange though.

vschumpy,

Just curious. How long does your full backups take? And how what is the size of the total data being backed up?

 

[vschumpy]

Tis all subjective based on what you are backing up, how, and what you are backing up to. Remember a brick level backup is optional and cannot be used to recover your server in a disaster recovery situation. Your backups of the mailstores/IS/DS is the priority.

vschumpy,

I didn't ask the question relative to my situation. I was actually jumping off topic, and wanted to know how long the full backups usually take in your organization.

How long my own backups take is irrelevant for exactly the reason I mentioned above. My response was not referring to your backups specifically, but stating that throughput and/or how long the backup takes is dependant on any number of factors.

You should be aware that brick level backup will nearly always be significantly slower than a traditional flat file or large database backup due to the very nature of what a brick level backup is/does.
