I wouldn't be so sure that 10 years is all you will need Mehdi
A few years back I attempted to unravel the retention rules for an
Australian State Government department for which I was working at the
time.
There were layers on layers of rules to work through and I never did get
to the very bottom of it; some of the stuff I did find was very
interesting.
some data was to be kept literally forever.
some data was to be kept for the life of the person concerned plus 20
years.
some data was to be kept for the usual 7 years
some data was required *not* to be kept. Personal data like old
addresses, bank details and so on was not to be kept longer than
operationally necessary.
This was a health department and ran hospitals, nursing homes, pathology
labs and so on. The infinite retention stuff was supposed to be
available for epidemilogical investigations that might be run in the
future. Since maternity hospitals were part of the picture, the life+20
years rule could be a very long time, and there is no way of accurately
knowing when someone has died, given that they may have moved anywhere
in the world over their life.
The moral of the story was that a proper unload/archive strategy was
needed for any system, particularly when it was retired. Long term
backups/archives of raw data in a TSM sense were simply not going to
meet the standard required.
Also needed as Richard has pointed out, is a strategy for moving data
from one medium to another on a regular basis as technologies change so
that it can still be accessed when required. Try reading an 8 inch
floppy today and you will have trouble, even if the data on it is still
good.

Thanks Daniel,
The longest period in regulatory rules is 10-years. I thought if you don't
use a cartridge for a long time (say 10 years) before storing data on it,
the "tape" loses its physical characteristics little by little.

Not sure for how long your regulatory rules state that you need to keep the
archived data on your 3592 cartridges but:
a) The lifetime of a cartridge(or, the data stored on it) can be counted
from the first use, not the production date. The physical cartridge itself
wont break down into dust, but the magnetics on the tape will sooner or
later be unreadable.
b) If you need to keep data for a very long tape, I suggest you get another
media than using magnetic tapes. The lifetime of the data stored on the tape
is quite limited comparted to MO media or something similar.

Ärende: [ADSM-L] the production date of a cartridge
Hi,
Is there any way to determine the age of a cartridge? We know the purchase
date, but it does not necessarily mean that the cartdige has been
manufactured around the same date. Maybe it has been stored for a long time
before we get it. To be more precise, we have thousands of 3592 cartridges
for old J1A cartridges. In order to make sure whether archive data is safe
during the period that regulatory states, it is essential to know when a
cartridge is physically "dead".
Regards,
Mehdi
