Since this is vmware backups

Since this is vmware backups BE communicate with your vcenter using vstorage API from vmware.

Using the API, BE tells vcenter to take a consistent snapshot of the virtual machine prior backup this to ensure consistency. When a consistent snapshot is taken, VSS-writers within the virtual machine makes the IO pause for a while during the snapshot procedure.

If vcenter are not able to do a consistent snapshot of the virtual machine, this is reported back to BE and you se an error about the snapshot errors.

Was not able to open the joblogs on my Macbook but it seems like this is the issue. If so, you should se a number of quisce-errors in the events log in Vcenter for the different virtual machines with this problem.

For the virtual machines with quisce errors;

- Install vmware tools if not installed.

- Instal BE remote agent (this will replace vmware tools VSS, must be done after vmware tools install)

- Reboot virtual machine (because of the VSS replacement)


This usually resolves the problem with "unable to quisce".
