I learned over the years about those allegations. It differs a lot over the 
years. Please define 'data held on mainframe'. Is it Business data like, 
payslips, stock control, logistic data, accounting, trade secrets, etc.?

Ok, what about movies, e-mail correspondence and their backups, 
documentation/policies/procedures/etc. about everything?

Then backup data should not be forgotten - Think Tivoli Storage Manager 
(previously ADSM). These nifty toys store network server data on mainframe 
storage. And that data is just about everything under the shining sun.

Now you mention it - movies - Those YouTube movies - What system is used for 
them for hosting and storing them? Just curious... (For what it is worth, I 
know Google is using a special hardened version of Linux system for their 
searching and cataloging system.)

PS: I was an ADSM admin and later became TSM admin before dropping that on a 
willing colleague. ;-)
