Space Recovery on Windows
Space Recovery uses the Storage Manager Server Agent to nd and recover unused disk space as reported by Windows. The
amount of space that can be recovered depends on the frequency and expiration of Storage Center snapshots. In general, more
frequent
Storage Center snapshots with shorter expiration times result in more recoverable space. To be eligible for release, a
snapshot must be expired with no Storage Center View Volumes attached.
Guidelines for Space Recovery
For best results, follow these guidelines for running Space Recovery:
• Schedule Space Recovery to run once per week during o hours.
Instead of running Space Recovery immediately on any volume, maximize the amount of space recovered by scheduling Space
Recovery to run once per week. If you run Space Recovery more frequently, note that Data Progression must run on the Storage
Center prior to Space Recovery in order to recover unused space.
• View storage trends on volumes running Space Recovery to see progressive results.
• Regularly-scheduled Space Recovery operations gradually result in more space recovery. To see the progressive results of Space
Recovery, view the storage trends of volumes running Space Recovery.
