You should remember these guidelines when using Space Reclaimer.
- For optimum storage performance, run Space Reclaimer as often as possible and until the entire NTFS file system has been scanned.
- Space reclamation is a time-consuming operation; therefore, it is best to run Space Reclaimer on your NTFS volume when there is a large amount of unused deleted space.
- The space reclamation process is CPU intensive, so run Space Reclaimer when storage system and Windows host usage is low; for instance, at night.
- Do not run disk defragmentation at the same time Space Reclaimer is running, as doing so can slow the disk reclamation process.
- In MSCS configurations, Space Reclaimer can be initiated from the owner node only.
- Although Space Reclaimer reclaims nearly all space from newly freed blocks, it does not reclaim 100 percent of the space.
