Note that I would not recommend Amazon S3 as your **only** form of

archives on optical media and/or tapes, it seems rather promising.
Surely it would be the *fastest* way to retrieve something, if the
alternative source (the media) were cloistered off site. Maybe the
redundant local media could be limited to
- re-writable dailies x6 (could even be skipped in the presence of a
reliable slave database)
- re-writable weeklies x4
with write-once monthlies.*
Even just $10 US per month could add up, over months to years, as
would any longer term storage (storing one gig per month for
"monthlies"), the annual cost would be $US 120 + ($12 per year of
"monthlies" accumulated). So the first year you would pay $132 and
the 5th year you would pay $180. The added $48 would be in place of
having to duplicate, and separately store, another 60 DVDs to provide
redundancy to what would otherwise be a single "store" of years of
data should the database get corrupted.
I think this would make tremendous sense. What further needs to be
done to marshal the support for it to happen? Do we need funding, and/
or to solicit one or multiple donors?
* For care that had been delivered more than a month ago, surely
monthlies would be sufficient (given that the monthly written 1-30
(average 15) days before the event could serve the purpose of
"baseline", and the monthly written 1-30 (average 15) days after
would show not only the rows that remained "live" at the time, but
also any rows that had been audited to that point. --- It is true
that records could have been manipulated in the window of time before
the next dump, but I cannot imagine any regulatory bodies would
*require* daily notarized backups be retained in perpetuity, that
would be a LOT of media!
