Bordering on the pedantic, I would like to add the caution that disc
mirroring through RAID or other mechanisms guard against only certain
kinds of failures, e.g. a hardware drive failure.
If the contents of a disc can be compromised by a software fault or
malware, the mirrored data is also compromised.
RAID solutions are only part of the solution set.
There is still a place for backups.
And if you can believe it: I have seen disc mirroring on partitions
on the same physical hard drive.
I did not know how or why this was done but left things as they were.
