How to resolve VSS or COM errors with Remote Backup

When checking the remote backup logs, you might come across the following errors –

Error: 19:05:18 An error occurred preparing VSS for backup: Unknown VSS or COM error

Error: 19:05:18 An error occurred trying to initialize VSS: Unknown VSS or COM error

Error: 19:05:29 Unable to recover from exception in backup process

The following processes appear to fix this problem –

Remotely log on to the machine with the error.

Increase the virtual memory allocation to the Backup Service in the console – see http://faq.scomis.org/kb3351/

Reconnect the client http://faq.scomis.org/kb4601/

 

 

Run a manual backup or await scheduled backup and check to see if the backup now completes successfully. If still an issue, assign call to the Server and Network Team.
