Tape back up may still be a continued (and massively declining sector). Who are the many people still trying to selling large tape libraries? I can name them: IBM. Oracle. Spectralogic. That's too few imho. Its a declining market.
IBM making bigger arial density films matters not - especially with them (IBM) in particular, shrinking their storage HW business for something like 18 straight quarters. Tape is a relatively small portion of their dwindling storage tin revenues
Tape recovery of large systems is, on the other hand, a different fish altogether. It's not a compelling story when you are in DR and can't read back a significant proportion of tapes from the vault. Especia;;y those not retensioned regularly, spanning several data and tape formats, and maybe with the catelogues gone. It's a terrifying and career-limiting prospect for any back up Owner.
Don't get me wrong I build a career on tape, and I love the technology in principle. But it's only just hanging on in there as a viable market sector for vendors.
