Depending on your amount of free space, it may be a good idea to change the VSS snapshot location for your drives. This can help prevent issues caused by the snapshots filling up the drive.
View VSS Shadowstorage
vssadmin list shadowstorage
This will list your current shadowstorage usage and locations. If the storage volume is the drive that's nearly full, you will want to change the destination.
Delete VSS Shadowstorage
vssadmin delete shadowstorage /for={drive letter} /on={drive letter}
The first step in moving the shadowstorage location is to delete the existing shadowstorage on the drive that is low on space. If you have any existing shadows this will delete them as well, possibly freeing up some space in the process.
Add VSS Shadowstorage
vssadmin add shadowstorage /for={drive letter} /on={drive letter} /maxsize={size}
- maxsize can be a size (20g, 800m, 1t, etc.) a percentage (25%) or "unbounded"
This will define where you want the shadowstorage for your volume to go. You can run vssadmin list shadowstorage again afterward to verify it is now set correctly.
