Before you backup your vRealize Operations Manager multi-node cluster by using vSphere Data Protection, disable quiescing of the file system.

1

Log in to the ESXi host with an SSH session, and power off all nodes.

2

Navigate to the /vmfs/volumes/virtual_machine_datastore/ virtual_machine/ directory, and open the virtual_machine.vmx file for editing.

3

Set the disk.EnableUUID parameter to false.

You may have to add the disk.EnableUUID parameter to the virtual_machine.vmx file.

4

Save and close the file.

5

Power on all nodes.

6

Open a console session to the virtual machine, and log in to each node.

7

Navigate to the /etc/vmware-tools directory, and open the tools.conf file for editing.

If you cannot locate the tools.conf file, run the vi tools.conf command to create a file.

8

Add these parameters to the file.

[vmbackup] 
enableSyncDriver = false

This runs a synchronization operation before the snapshot, and does not run a freeze on the file system.

9

Save and close the file.
