RAID Scrubbing
RAID scrubbing helps maintain the consistency of data on the NAS. QTS scans the sectors of a RAID 5 or
RAID 6 group and automatically attempts to repair any detected errors. You can run RAID scrubbing
manually, or on a schedule.
Tip
QNAP recommends performing RAID scrubbing at least once a month to maintain system
health and prevent data loss.
