Volume shadow copy error 80042316

You see the following statement in the log files on the client side:

Solution

This problem typically occurs when some other program is using VSS for the same volume. Consider the following possible solution:

• If some other program is running backup and has locked the volume, wait for it to finish and then restart Syncrify
• Schedule the backup jobs so they don't overlap
• Apply this as well as any other hotfix from Microsoft.
• Perhaps a previous backup left VSS hanging. In that case, try using the following command to see how many shadows exist on the system. Open a command console and type the following line.
  vssadmin list shadows
  If you see a shadow copy from a previous job, try stopping the VSS service in control panel and see if that fixes it. If not, reboot the machine.
