Exchange 2010 and Reverse Incremental

Post by doggatas » May 09, 2013 6:30 am

Hi

I am about to start using Veeam 6.5 to backup our Exchange 2010 active mailbox server (DAG), it's passive member is located in our DR datacentre. The mailbox server is a virtual machine hosted on an ESXi 5.0 update 2 host(S), which in turn is attached to an IBM DS3524.

I have configured the appropriate cluster timeout value for the DAG cluster to prevent inadvertent failover, I have also configured the databases to never automatically mount in the DR site. Exchange server DB sizes range from 30Gb to 70Gb across 7 databases for a total size of 620 Gb.

I am already backing up supplementary VM guests such as the Hub transport, client access and BES server using Veeam reverse incremental (8 restore points), which I must say is working superbly. The mailbox server is being backed up by Symantec Backup Exec at present. Based on the success of the current Veeam backup job I am ready to make the jump to use Veeam to backup the mailbox server.

I also am loving the Exchange Explorer, it is brilliant. I can't recall, but I trialed this program when it was sold and labeled under another name, I put forward to the company to buy it back then but was not successful. So good to see I finally have my hands on it.

Now to the real question. Is it advisable to use reverse incremental to backup Exchange 2010? Will this truncate the log files correctly provided i tick the application aware check box? The plan is to run the job daily with 8 restore points?

Cheers and thanks in advance.

Cheers
David

Hi, reversed incremental is generally slower due to extra I/O required, so just do a test run and make sure you can fit your backup window. Yes, log truncation will work fine if you enable application-aware processing.

Veeam Explorer for Exchange was never sold separately or labeled under another name, we've only developed it in-house recently (last year).

Thanks!

Thanks for the reply. Have only just gotten around to backing up the Exchange 2010 server for the first. Being the first time and a bit of a test, I selected application aware (VSS) but do not delete transaction logs as I am still backing up with B Exec, only for another week thank god.

Given I selected do not delete logs should I expect to see the following in the event viewer on the mailbox server:

Exchange VSS Writer (instance 3eff65c5-ac4e-4d73-8c55-43a2e4df1a41:408) has completed the backup of database 'DB_E-G' with errors. The backup did not complete successfully, and no log files were truncated for this database.


I am hoping this is because i chose not to delete log files. The above event was logged for all databases on the mailbox server.

Cheers
David

Yes, these kind of messages are expected when you choose not to truncate transaction logs. Thanks!
