Richard, this is a good question. The answer is largely
redundancy. It is hard to always check that your tape is readable on
another puter (I remember one System 36 experience where the tape
made and read its own data, but it was off-kilter). And it is
cumbersome to have more than one tape offsite at a time.
Recently our own CPAs got into a jam with a PC network (I think)
RAID-system backup (unreliable complexity, whatever messes up one
disk can mess up another, better for hot-swapping than backup
assurance) and one tape .. which was unreadable, corrupt. Plus, also
recently, one company exec ran into a personal Apple backup problem.
Thus we want to enhance our mission-critical business tape backup
system with a good solid cloud backup. For the anticipated $100/month
or so, we end up with a far greater peace-of-mind level. If it was
personal budget, maybe do not bother, simply watch the tapes, or add
a secondary tape method. However for a solid small business, just
want a fuller strategy. Originally I was approached about the
Carbonite/Mozy attempt (where you would likely send all the iSeries
data over the lines every day ... slowww) and we moved to the more
robust storage possibilities I mention here.
The speed issue is largely taken care of by the iSeries-savvy
software, which reads hashes and only resends changed blocks. Thus
there is a real reduction in time after the first save. (Also uses
compression algorithms.) We make sure to get a 30-day OK with
whomever we choose.
Hope that helps.

And our tape backups are quite solid, including taking off-site,
so this is meant more for auxiliary than anything else -- minor
restores will likely be few and far between, since we could use the
tape and simply do not do a lot of restores.
