Once you have scheduled a Windows Backup on a server, you might notice that the scheduled task is failing to complete.
I have noticed this problem on one of our servers where the backup failed to complete with the following error message:
Backup failed to complete. There is not enough disk space to create the volume shadow copy on the storage location. Make sure that, for all volumes to be backup up, the minimum required disk space for shadow copy creation is available. This applies to both the backup storage destination and volumes included in the backup. Minimum requirement: For volumes less than 500 megabytes, the minimum is 50 megabytes of free space. For volumes more than 500 megabytes, the minimum is 320 megabytes of free space. Recommended: At least 1 gigabyte of free disk space on each volume if volume size is more than 1 gigabyte.
Detailed error: Insufficient storage available to create either the shadow copy storage file or other shadow copy data.
After further investigation, I have noticed that the problem is in the free space on volume for shadow copy creation.
To solve this open Computer Management and from the left pane navigate to Disk Management.
Now, in the right pane right-click on C drive and select Properties.
Select the Shadow Copies tab and Select the volume marked as: \\?\Volume{317a3d75-1039-4978-a621-4efd6bee252e}\ (you’ll have a different drive number here), and click Settings.
From the Storage area change the Located on this volume drop-down list selection to C: drive and set the limit to at least 1024MB.
Click OK and close Computer Management snap-in.
Try to run the Windows Backup again. It should now run without errors.
