RAID6 only works if the machine is working fine. If something happens that toasts the whole thing then youβre fucked unless you have a backup offsite.
Backups are important, but we were talking about drive failures. Backups help when you screw up the data; RAID6 helps when drives go bad. If you donβt trust the hardware, RAID.
Backups only means youβre down until you restore; RAID5/6 means you stay up.

Right, but he was talking about the 3 2 1 rule and you recommended RAID6.
