How does bitrot protection actually work?

Can bit rot protection be enabled on Home folders in OS 6.4.x? Unlike shared folders, there is not a check box to enable bit rot protection on Home folders.

I replaced a ReadyNAS Duo v1 with a RN312 in a RAID 1 configuration last year for home use. I only use the RN312 for user backups, and these backup files are written to folders in the users' Home directories. I then use ReadyNAS Vault to provide an off-site backup. I would certainly like to enable bit rot protection since many of the photos and music files in these incremental backups are static. Perhaps I need to create shared folders and then adjust the permissions to only allow access by the individual users?

I don't understand why ReadyNAS does not share more information on exactly how checksums, bit rot, and RAID reconstruction with checksums works in OS 6 for RAID 1, 5, and 6. While the information in this thread is helpful, I still have a number of questions. In the Enterprise storage array space, vendors like NetApp have always published in the open literature the specifics of how their checksums (data and metadata), file identity blocks, raid scrubbing, and bit rot work. For example,  a Usenix paper in 2008 reported data for three years on 1.5 million disk drives in NetApp storage arrays at customer sites. Over this time, they found 400,000 checksum errors, of which 8% were discovered during RAID reconstruction often leading to data loss, The file identiy blocks identified an order of magnitude smaller number of errors due to things like lost or misdirected writes. The superior error handling performance of OS 6 is a selling point for ReadyNAS, particularly given the slower performance for the price compared to the competition, and you should step up and let your customers understand exactly how it works.
