So, um, how do you take one of *those* off-site?
The major problem with spinning backups is that they're *spinning*: a tape,
in a storage box, is about 4 orders of magnitude less likely to fail than a
spinning hard drive -- much less that you *multiply* the MTBF's to get the
overall failure rate on a JBOD. It's a little better on a RAID, of course,
but still nowhere near tape.
And it's easier to *train* tape, too.
