There is not enough disk space to create the volume shadow copy

Hi @Dexter Southerland ,I am Henry and I'd like to help.

The error "There is not enough disk space to create the volume shadow copy" during your Windows Server 2022 Standard Backup typically occurs when the Volume Shadow Copy Service (VSS) doesn't have sufficient space to create snapshots. Here's how you can resolve this issue:

1. Check Disk Space

Ensure there is enough free space on the volume where the shadow copy is being created (usually the backup destination or the source volume).

Free up space by deleting unnecessary files or moving data to another drive.

2. Adjust Shadow Copy Storage

• Open Command Prompt as Administrator and run the following command to check the current shadow copy storage: cmd

    vssadmin list shadowstorage
  

• If the allocated space is too small, increase it using: cmd

    vssadmin resize shadowstorage /For=C: /On=C: /MaxSize=10%
  

  Replace C: with the appropriate drive letter and adjust MaxSize as needed (e.g., 10% of the drive size).

3. Use a Dedicated Backup Drive

If possible, use a separate drive for backups to avoid conflicts with the source volume's shadow copy storage.

4. Check VSS Writers

• Run the following command to check the status of VSS writers: cmd

    vssadmin list writers
  

  If any writers are in an error state, restart the associated services or reboot the server.

5. Update Windows Server

Ensure your Windows Server 2022 is fully updated. Updates may include fixes for VSS-related issues.

6. Review Backup Configuration

If you're performing a "Bare Metal Recovery" or "System State" backup, ensure the backup destination has enough space to accommodate the entire backup size.

Let me know if these steps help.
