This case is an example of exactly where it is not appropriate to say such a thing. The OP is clearly using the mirroring ability of RAID1, then breaking the mirror to move the copy offsite. In fact, this is exactly an implementation of a "proper backups". For further information, when people say "RAID is not backup," they are referring to the situation where people rely solely on RAID to cover all aspects of backup. They simply don't think through all the scenarios of when you need a backup, such as when files are deleted, filesystem corruption, fire/flood, virus, etc... People using RAID like this don't have tapes, don't have offsites, and rely on all data sitting within the machine to be safe. Again, that's clearly not how it's being used here.
