Quiesce: If the flag is 1 or true, and the virtual machine is powered on when the snapshot is taken, VMware Tools is used to quiesce the file system in the virtual machine. Quiescing a file system is a process of bringing the on-disk data of a physical or virtual computer into a state suitable for backups. This process might include such operations as flushing dirty buffers from the operating system’s in-memory cache to disk, or other higher-level application-specific tasks.

 

Note: Quiescing indicates pausing or altering the state of running processes on a computer, particularly those that might modify information stored on disk during a backup, to guarantee a consistent and usable backup. Quiescing is not necessary for memory snapshots; it is used primarily for backups.

 

 

Conclusion:

 

  • From the Logs we can see that the issue is happening while we are taking backup of the VMs with Quiesce enabled. This could be an issue either with the Sensitive VMs unable to handle the Delay while the OS is in freeze State.

 

  • Please check and test by taking backup of a VM without Quiesce and check the status.
  • Please check from the logs inside the VM if there is any Failures during this operation.

 

As discussed earlier please run the ESXTOP with the below commands to review the logs from the Performance standpoint.

 

esxtop -b -d 600 -n 3 >/var/volume/<Datastore Name>/esxtstats.csv

600  *  3 = 1,800 Seconds :

Please Note that this is requires a good amount of space, so please use a datastore which has a good amount of free space available.
