Problem
This error is shown when a VSS provider blocks (or vetoes) the creation of a snapshot and can be due to:
- Shadow Storage space on the source drive is insufficient or not configured,
- Installed software has installed its own VSS provider,
- Existing VSS provider component has become corrupted.
Below are the solutions:
Solution - Increase shadow Storage Space
To see the amount of storage space allocated and used for Volume Shadow Copies run this command from a command prompt with elevated privileges:
Vssadmin list shadowstorage
To allocate more storage (e.g. 50GB) run this command:
vssadmin resize shadowstorage /For=C: /On=C: /MaxSize=50GB
This error may also require an additional action on Server OS:
Solution - Enable shadow copies on volume
- Open Windows Explorer and navigate to This PC
- Right click any of the Disks that you wish to image and select Configure shadow copies...
- In the Shadow Copies dialogue select a disk, click Enable > Yes then click OK to apply changes.
