IMHO we're talking about system parameters, those in software, not
physical aspects of tape media and drives.
BTW: Why do you suggest 5 years period ?
Most vendors provide much longer lifecycles for their media, and the
drives able to read the media are available for longer time as well.
For example Sony AIT is able (according to Sony specifications) to keep
data for 25+ years. Data written in MAGSTAR drive (1 years ago) are
still readable using last MAGSTAR, AFAIK there's no EOS date yet.
Last but not least: virtual tapes. You can keep them for years. <vbg>
As well as drives. You migrate both drives and media to newer (physical)
devices.

As a practical matter, there is no 'permanent' tape retention. For one,
the media ages and becomes unreliable. Secondly, the devices needed to
read/write the data eventually wear out and are replaced with newer
technology.
For permanent *data* retention, you might consider a five year cycle.

Subject: Tape Retention - Permanent
I would like to keep some tapes for ever - permanently. Prior to the
Y2K era, I used the parm :RETPD=99365. Is this still applicable?
