Cause

From the logs we see that the quiesced snap shot operation fails because VMware Tools to freeze the Linux filesystem takes too long due to high I/O on the virtual machine. During the freeze operation, VMware Tools does not respond, causing the host to abort the quiesced snapshost operation.

Resolution

Refer to the following KB from VMware that explains the issue:
http://kb.vmware.com/kb/2116120
To fix this issue please follow the action plan:

Action Plan.

1. Clean up all the old snapshots on the server by cloning the virtual machine or by performing a V2V conversion of the virtual machine
2. Upgrade one Esxi host and migrate the vm to that host and perform the backup operation
