Zmanda Windows Client uses Microsoft VSS (Volume Shadow Services) to perform backup and recovery of file systems and applications. VSS writer services for the application must be stable and must not have any error for successful backup.
Windows command vssadmin list writers returns the state of all VSS writers on the system. If the required application writer’s state is not stable, restart the respective service (sometimes system reboot might be required). After restarting the service or rebooting the system, recheck the VSS writer state using the same command.
On Windows Vista and above, Above command will require Administrator privileges.
The list below shows the name of the VSS writer and the Windows Service associated with the writer. Restarting the Windows service will restart the VSS writer
