What Is Shadow Copy
Shadow Copy, also known as Volume Shadow Copy service, Volume Snapshot Service, or VSS is a technology included in Microsoft Windows. It can be used to create backup snapshots or copies of computer volumes or files whether you are in use or not. This technology requires either NTFS or ReFS Windows file systems to create/restore shadow copies.
The Shadow copies can be created on a local disk, an external drive, or network volumes. With this service, users can schedule a Windows backup or automatic system restore point. However, users also encounter various issues with the service, such as “VSS was denied access to the root of volume”, “Volume Shadow Copy error 0x8004231f”, and Server 2019 Shadow Copies missing.

Step 3. To allocate more storage space for Shadow Copies, select the target volume and click on Settings.
Step 4. In the pop-up box, select the target volume for the copy, and select the No limit option next to Maximum size if you want to keep the storage space for shadow copies unlimited. Alternatively, you can specify the shadow copy size limit.
