Good day all,
I just deployed a new Netbackup environment and need some assistance please. I apologise if this has already been asked but I cant seem to find anything with the same issue as what I am experiencing.
I have 2 x Exchange 2010 SP3CU11 boxes running on top of Windows Server 2008 R2 x64. The initial granular backup worked perfectly with no errors. I have done all the necessary config with the "Replace a level token" and added the user to the correct groups etc, however my Incrementals been trying to run and failing with the following errors in the job log;
<LOG1>
03/03/2016 16:20:06 - Critical bpbrm (pid=6424) from client server1.company.here: FTL - snapshot preparation failed - Error attempting to find volumes to snap., status 130
03/03/2016 16:20:06 - Critical bpbrm (pid=6424) from client server1.company.here: FTL - snapshot preparation failed - Error attempting to find volumes to snap., status 130
Could not fetch snapshot metadata or state files (4207)
</LOG1>
<LOG2>
03/03/2016 17:27:53 - Critical bpbrm (pid=5312) from client server1.company.here: FTL - snapshot preparation failed - Unable to backup Exchange database. It may not be mounted., status 71
03/03/2016 17:27:53 - Critical bpbrm (pid=5312) from client server1.company.here: FTL - snapshot preparation failed - Unable to backup Exchange database. It may not be mounted., status 71
Could not fetch snapshot metadata or state files (4207)
</LOG2>
<LOG3>
03/02/2016 18:00:27 - Critical bpbrm (pid=124166) from client server2.company.here: FTL - snapshot preparation failed - Unable to backup Exchange database. It may not be mounted., status 71
Could not fetch snapshot metadata or state files (4207)
</LOG3>
I have done the following;
- Checked the location "C:\Program Files\Veritas\Netbackup\online_util" to ensure that permissions are correct on the folder
- Restarted VSS on the client
- Checked that the DBs are in fact mounted in Exchange
- Forward and reverse records working ok with bpclntcmd
- Check the credentials for the Service Account that runs the Exchange Backup
- Checked that its in the correct groups and has the correct Local Security Settings
I dont understand how one backup performs perfectly and then anything after that does not complete successfully.
I look forward to your replies.
Thank you kindly!

Is this a MS-Exchange policy type?
The reason i ask is that it looks like a VMware policy type .. and they do not support incremental backups, only full ones
Even an MS-Exchange policy type will not do any GRT during an incremental backup - it backs up only the log files ... that being the case if your exchange uses circular logging it will cause it to fail

Hey Mark,
Yeah it is an MS-Exchange Policy type.
Circular logging is currently off as well.
I will keep reading the admin guide and see what I can come up with. Ideally I just want a weekly/monthly full with diff/incremental in between.
Thanks!

The client name in the policy is the FQDN.
I do not have a DAG in place so is just a straight forward backup of the mailbox databases on individual hosts.
I havent checked the bpresolver log at all, I will investigate where they are and whats in them.
Thank you for the advice! :)

So, no cluster? 2 standalone Exch servers?
With separate policies?
What is in Backup Selection of Exch policy/policies?
Are you seeing this error for one or for both Exch servers?
bpresolver log is for DAG.
Other logs needed on Exch servers:
bpfis
bpbkar
nbfsd

Hey Marianne,
Thank you for your quick responses :)
That is correct, I have 2 backup domains with AIR between the two for replication. My Exchanges are not clustered and are indeed both standalone.
They have separate policies and has 2 different masters as well.
Backup selection I just changed right now but I had 3 x Exchange DBs with a New Stream between them, and the other policy had only Micosoft Information Store with a single stream.
I am seeing this as a very intermittent issue as sometimes after a reboot it works fine with the exact same settings and everything. I get a feeling this is a VSS/Snapshot issue since I see the following in the logs, see attached.
I have removed any specific identifiers for safety reasons. I hope this helps.
Thank you kindly

Hey Marianne,
Thank you so much for your assistance. With diskshadow and vssadmin I was able to get rid of the vss issues. It turns out that my vss on C: was stuck and I couldnt alter it at all. I deleted all the disk shadows and then changed the shadow copies manually.
