This error occurs when the Application vss writer ( Exchange, MSSQL) in Guest VM machine is unstable.

Vembu VMBackup checks the writer status stability of the application running in guest VM machine during every backup\replication schedule. If the writer status of application in guest machine is UNSTABLE, this error is caused.


Restarting the host or the application in guest VM machine might resolve this writer status issue.

After restarting, manually check the status of vss writer by executing the below command using command prompt in the guest VM:

"vssadmin list writers"

This lists out the status of the writer’s available machine.
