- Increase the allocated replica volume size by using the modify the disk allocation wizard from the DPM GUI. Run a full consistency check.
- WSB bare metal recovery (BMR) backups use Volume Shadow Snapshots on the System Recovery and EFI Partitions. Ensure these resources have at least 320MB of free space for Volume Shadows Snapshots (VSS).
