Data integrity rn104
I am using a rn104 for my main media server and run backups from the rn104 to external drives MY drives in the nas are WD REDS in JBOD mode What I was wondering is there any data integrity check...
Could you also explain a little more on how bit rot protection works
1 How do I schedule scans
2 How would I know if there is corruption
3 Does it scan the file when it's being accessed
4 Is there any point in enabling it as my setup is JBOD not RAID
And a couple of different questions
A) As my setup is not raid is there any point in using the volume tools scrub, balance, defrag, disk test
B) what is the best ethernet teaming policy I currently use round robbin

More generally - If your switch or router supports LACP, then use that. Otherwise I'd normally suggest ALB and TLB (in that order). All the non-LACP modes can cause problems, so if you see connectivity or speed issues then you should revert back to non-bonding mode.
