Exchange 2010 - Logs not deleting?

[Jaykullar]

Hi All,

On a new solution backing up Exchange 2010 DAG on NBU 7.1 for the first time. My backups are fine, however the exchange logs are not being truncated by NetBackup.

Please see below my policy output:

I also run a daily full schedule. Its a pretty standard policy.

Ive checked through the logs and i cannot see anywhere "Exchange Logs Truncated" in bpbkar.log as i would in Exchange 2007. Circular logging is not enabled and im running Full's only. Also there are no errors on the application log.

I also noticed this in the bpbkar.log, i dont know what it means?

exchange_shadowcopy_access::V_Read_FI_Metadata(): INF - Not enough room in the bfr for the BEDS Stream Header, 14 bytes read
01:25:56.613: [8776.9068] <2>   (I see this quite alot in cheap exchange backup)

Anyone have any idea's on this?

Many Thanks

Jay

I would expect an ESE entry in the application logs that the backup had completed successfully with perhaps a note about the logs?

Are you using 7.1.0.2 on both Media Server and Client?

If you environment working correctly - if replication is not ocurring correctly the logs will not get truncated.

I also see you have multiple data streams enabled - does you policy produce one job or more?

If it produces more than one job do any fail? (as this will prevent the logs from being truncated for all storage groups)

Thanks

NetBackup merely notifies Exchange that the backup was successful. It is then up to Exchange to truncate transaction logs.

Have a look at this section in the manual about Full backups:

This schedule type backs up the Exchange Server database and associated transaction
logs. Exchange truncates all committed transaction logs after NetBackup notifies it that
the backup succeeded. In replicated environments, the truncation is scheduled and does
not occur immediately.
