How does bitrot protection actually work?
I understand the concept, but am curious how it is actually implemented on 6.2.0
Hi, I've got an RN102 with only one disk installed.
The NAS initialized with a single volume under XRAID2 JBOD.
Checksums are enabled on the volume because the default set of shares have bitrot protection enabled.
On one of the shares, I disabled bitrot protection (since bitrot can't be fixed without a redundant copy) and set snapshots to never and then restored data on to it over usb.
I presume BTRFS has created checksums for these files? Does that mean that, even with bitrot protection disabled, BTRFS will detect bitrot and alert me to the problem?
Is there any benefit in enabling bitrot protection in this scenario?
Or should I be switching checksums off as well? (although I might add a second disk later...then I might have the option of enabling automatic bitrot protection on the existing data)
Thanks
Paul.
