I heard about Kim Dotcom, but I don't understand what you mean.
I'm not talking here about legal issues, so there is nothing to love.
And the cloud is still someone else's computer, isn't it?
Keeping data in cloud is still keeping data on someone else's media like
disk or tape. Usually tape for large amounts and reasonable prices (with
horrible access times). The main difference is you don't know where is
your data.
(off topic drift)
Of course cloud is valuable in man cases, especially for smal and medium
businesses. Sometimes "don't do it, use our services" is true. You don't
buy brewery to have a beer to a dinner or you don't buy taxi car to get
to airport. However many companies still have their own truck fleet.

There is no cloud. It is just someone else's computer. ;-)

I do a backup to spinning storage, then a copy of that backup to Azure

Any medium you use will have failure modes.
Multiple PiT recovery is good for "whoops!" moments and possibly for
audits.
Large or small, each shop must do it's own risk assessments in the
context
of its own obligations and priorities.

Subject: Re: Storage & tape question
Probably many others will chime in on this. I have lost RAID 5 arrays
with
two disk failures within an hour of each other. RAID is nice, but one
must
allow for failures.
Long ago I was involved with reading archived tapes and transferring the
data to CDs. The programs involved were home-written and the project
ended
up going nowhere. However, we discovered that tapes kept too long
started
having errors. (At that point, for the CD copy, we just logged the error
and accepted the corrupt data; what else could we do?) How long is "too
long"?? It was variable, but measured in a few years. The advice then
was
to minimally read the tapes every year or so to "retension" them. Don't
know if this would apply to more modern tape media. (We also discovered
that locally "burned" CDs are not expected last forever.)
IMHO, the key point for tape backups are (1) off-site storage, (2)
multiple PiT recovery, (3) logical error recovery. All this can be done
with disk-only environments involving remote copy and lots of disk
space,
but all that becomes expensive for smaller shops.
