For reasons buried in the long forgotten past we have NAS units without bit-rot protection on almost every share/file. Most systems are using Raid1enabled.
If I understand this circumstance properly, once bit-rot is enabled I need to actually copy and read back the associated files to get the protection enabled. Is my understanding correct or is there some way to force a checksum event for the newly enabled bit-rot files/shares?
Would doing a scrub function do the same thing – establish checksums for existing files?
