6.2.0 has no manual to download
There is no manual for the new firmware 6.2.0 release. A manual is needed to explain in better detail the new features, how to use them and what they are. I have several question in regards to 6...
Bitrot protection is not the same at all as CoW. It depends on CoW, but it is different.
With CoW every time you make a write it doesn't overwrite the existing file but writes to empty space. This is why files that are written to a lot can fragment quickly.
Bitrot protection makes use of the md raid layer and the filesystem layer to detect when a bit is flipped (e.g. a 1 swapped with a 0 corrupting a photo) and correct it.
Since early on with the ReadyNAS we have made sure to make maximum use of data protection provided by RAID.
For years as long as multiple drives don't lose data in the same stripe at the RAID level, we've always tried to recover data from good drives.
If different drives develop different bad sectors on different locations, we can still keep your data intact.
Today, with BTRFS checksums, we take this to another level. We not only know if data is corrupted, but we also try to pin down which portion of data is corrupted on which drive, and use RAID redundancy to kick out corrupted data and recover uncorrupted data.
