Caveat of Disabling Virtual Machine Quiesce

rsamora

On my really busy VMs, mostly database servers, I was getting a Status 156 because the server was too busy to respond to NetBackup.  If I go into the Vware/Advanced tab in the policy and disable virtual machine quiesce, the job finishes successfully.  What are my vulnerabilities if I leave the setting disabled?  What will I not be able to recover?

NBU 7.6.0.1

vSphre 5.1.0

Windows Server 2008 R2

 

Thanks in advance,

Randy

Hi Rsamore,

I do agree with your concerns however its not recommended to disable this parameter

please verify the below link and notes...

If this option is disabled, the snapshot is created without quiescing I/O on the virtual machine. In this case, you must perform your own checks for data consistency in the backup data.

Caution: Symantec does not recommend that you disable quiesce.

Thank you for the response Sri.  I found articles stating the same thing but the articles were all 2 years old or older.  I was wondering if anything had changed with 7.6.

Disabling the option and the backup is not consistent anymore. Data may be damaged and the backup is worthless.

Thank you both for the great news :)  Back to client based backups.
