5 years is an easy one. Get LTO or 3590 or 9840/9940 and you have done the
job. The problems can come if go closer to 10 years (other issues to
consider as well). And if you have to achieve 20-30 years there is only
one answer - permanent WORMs + 2-3 (!) copypools.

Subject: 5Yr Retention Was RE:
Welcome to my world. We are looking at the same thing. Our current
solution is to make a copy of everything to CD, and keep a copy of them
offsite.
My thoughts was to use something like HSM, and keep a backup, or if you
don't need it available, archive it for 5 years and let it expire at the
end.
Our use needs access on occasion, so we keep a vault full of CDs, with our
DR copy of the CDs, offsite. All the CDs are labeled with the date of
data
and type of data (we generate 4 to 12 CDs daily, with a nominal day being
6
CDs, so 5 years worth is quite a few). Eventually I hope we move to DVDs,
but we will probably want to do one per day even if it is not full.
One company I worked for had a contract to do permanent storage for a
nuclear power plant. They did CDs for all the documents, and kept one
onsite and another offsite in another city, or at least that is what I
heard
it was supposed to be that way. TSM and I think with HSM (adsm at the
time)
managed the data. I don't have any more details on that implementation.
