The author claims about 3 MB per A4 page, so 1 TB could be backed up to about
700 reams.
I think the paper would last longer than the ink though.

You can also specify volsers. Very useful if one is damaged.

Dave,
This is a data migration problem, something very common in mainframe
migration/modernization projects. There are ETL tools (Extract-Transform-Load)
to help with doing such projects.
But first you need to establish the goal of migrating the data. From what you
describe, I could see
Dave,
In 2006 I did a project in Ohio to offload a bunch of data files to MS SQL.
They had completed a SAP implementation, but had not bothered to deal with all
the historical data left behind on the old mainframe. They had VSAM files,
QSAM disk files, thousands of tapes, and even a few IMS

If you really mean DVD,
at 10 years as well.
Technology changes so fast that there isn't a really great long term storage
option.

The life expectancy (readability) is at most 10 years for DVD and CD's .
Whenever you are archiving data, you need to ask the question: what is the
expected Standard of Care.
IMO, data archival is often a CYA proposition. You may think that the data is
a bunch of old junk, but you are unsure
With the reference to moving data files from z/OS to an ASCII platform
and intending to read that archived data, for any binary file, that
is, a file that can contain non-pure-text data, the PGM=FTP on z/OS will
delete ALL of the BDWs and RDWs from any dataset with RECFM=V or VB or VBS,

Great reply. Thank you for pointing this out.
As a small side question (I have never had to do this) how does one identify
tapes that need recycling?
I have just done recycles on percent valid and was never worried about doing
it based on device type.

Come on egypt tech??? And certain types of paper can last with the proper
conditions can last a few hundred years but when we are talking IT we are
talking machine readable.

Ps OCR is not an option.

Why not print it all out? Then get an army of Monks to transcribe to archival
parchment scrolls using quill pens and an ink formula from about 2000 years
ago. Seal the results into ceramic pottery vessels and place in a cave,
somewhere near the Dead Sea. Roll a big rock in front of the cave
You can also specify volsers. Very useful if one is damaged.

I know you are kidding, right?
Have you seen some pictures f the scrolls? They are not easily readable cracked
with age and the only thing that helped save them was the lack of humidity in
the desert. Now I realize. There are people that have partially that deciphered
them but we are
