Maintenance : Data Scrubbing
  
Data Scrubbing
C-Series gateways can perform RAID data scrubbing. During data scrubbing, the cloud storage gateway reads all the disks in a RAID array and checks for defective blocks, thus reducing the likelihood of silent data corruption and data loss due to bit errors.
By default, automatic scrubbing is performed on a weekly basis for all defined RAID arrays. It can also be run manually for specific arrays.
