Last Updated 8 years ago
Since DSM 6.1, the system is able to detect silent data corruption and repair the corrupted files in general cases with the file self-healing feature.
The file self-healing feature is currently available for the shared folders located in a Btrfs volume which was created with one of the following RAID types:
Once the creation of shared folder is complete, this option can no longer be altered. You can go to Control Panel > Shared Folder to check if, in the Advanced tab in the shared folder's edit window, the Enable advanced data integrity protection checkbox has already been ticked.

- RAID 1
- RAID 5
- RAID 6

- Synology Hybrid RAID (SHR/SHR-2) with more than one drive
Note:
- The file self-healing feature is currently only available for the shared folders mentioned above. The files stored on file-level iSCSI LUNs created on a Btrfs volume will not be protected with this feature.
