Netbackup and Microsoft Exchange Server 2010 SP3

Hi!

We are currently using Netbackup version 7.6.0.3 as the backup software in our environment. As of now, and with several previous versions of Netbackup, during backup of our Exchange Server 2010 DAG databases, all of the Mailbox Servers are getting errors in the Windows Event Log with ID 6, "Cmdlet failed. Cmdlet Get-PublicFolderDatabase, parameters {Identity=xxxxxxx}".

DAG consists of 3 mailbox servers, and 3 database copies for each database. Backup of passive copy, then active copy if passive copy not available.

May be irrelevant, but we also have a CAS NLB array consisting of 3 cas servers.

Attached are a picture of the Exchange policy in Netbackup admin console:

And here is an example of the error event:

My question is this, is there a correlation between our Exchange policy settings and the error in the event log?
The error seems to occur several times as the backup jobs are working!

No there is no relation and I dont think this error is causing any kind of backup failure.

Also no action required on this error as well

Ok, thank your for your answer.

Do you think there is any way to prevent Netbackup from running "Get-PublicFolderDatabase" on every regular mailbox database?
Amit KumarCommented:
When you select DAG there will be option to select DBs just deselect it, but there if you select DAG node only and exclude manually public folder then there will be issue while u create new DB because it will not be selected automatic.
EnsuremeAuthor Commented:
So if I understand you correctly, it is possible to set some sort of "bypass public folder", but that would cause problems with backup at later points when creating new databases?
