Related question on this - has anyone done a business case / justification that stacks up - migrating legacy tape data to new formats versus just keeping the old tapes ? Its a lot of work to migrate the tapes as David indicates, and potentially you may never need to restore any of the historic data.

I am copying some backups from 2006 (~ 3 years old), and experiencing some increased failure rates, as well as drive issues with these tapes that have sat at iron mountain for 3 years. 3.
