For this reason, everyone who is running BTRFS must ensure that data scrubbing is periodically running. With that said, there are downsides of data scrubbing, with the main issues being performance degradation and the overall duration of the data scrubbing process. Please understand that the information above is greatly simplified to present the data scrubbing process in an easily understood manner. Instead, shared folders must be configured in a way that enables data checksum functionality. When creating a shared folder, the enable data checksum for advanced data integrity option below must be enabled.

Small steps to big protection for your storage. Data scrubbing, as the name suggests, is a process of inspecting volumes and modifying the detected inconsistencies.

You go into your synology to retrieve one of your summer pics and while you expect to see the left image, you find yourself with the one on the right. Not fun right? RAID scrubbing can ensure data consistency but it cannot tell which data block is incorrect but Btrfs data scrubbing does exactly that.

If one of the drives fails, RAID 5 will repair the missing data by using Pa and contents of the remaining two drives. Btrfs data scrubbing File system data scrubbing employs the checksum mechanism to check the volumes in the Btrfs file system. Installation, Configuration, Migration, Expansion.
