There must be a lot of tiny files that are not duplicates being backed
up. If the source can be identified, maybe they could be tarred or
zipped in a pre-user command instead of backing up those directories
normally. If it were mine, I'd probably pull the 'miirror' set of
drives out of the raid10 and add a new raid1 of a pair of 2 or 3TB
drives formatted as XFS and start over, leaving the old set so you
could switch back if you had to do a restore before you built
sufficient history in the new archive.
