A raid0 or raid5 array is the most suitable option for long term backup, as

Sure, a small company I know decided a raid array on their server meant
they didn't need to backup. The sever fell over one day and trashed the
whole array, they lost everything. Hard drives inside an active machine are
a very bad idea for long term backup.

Fell over??? As in dropped to the floor?

Fell over as in stopped working properly - I don't know the details

Personally I have seen Win2k trash a (cheap) stripped array because one of
the drives was a bit sticky on power up. The RAID BIOS didn't recognise the
set and w2k thought the remaining drive was corrupt and attempted to 'fix'
it on boot without any operator intervention.

A RAID 0/5 protects you against drive failure, it offers no protection
against all the other ways data can be lost.
