How to fix Error code: 0x81000037 when using Windows 7’s Backup and Restore.

I have a few private clients that I have setup Windows Backup on to send data to a NAS drive. All works fine, until I get hit by an email saying backup isn’t working.

Twice now, it has turned out to be the same error code, and an error about not being able to read from the shadow copy.

The backup was not successful. The error is: Windows Backup failed while trying to read from the shadow copy on one of the volumes being backed up. Please check in the event logs for any relevant errors. (0x81000037).

I spent an age trying lots of different fixes – but the issue is NOT with your backup drive or location – its actually your PC/Laptop, and probably your anti virus. In my cases, it has been down to Security Essentials, a quick clear of the infected items (History > View all) and the backups work a treat
