I have had backup tapes of various kinds (DLT, LTO, etc) go bad over time. Yes I kept statistics. Sometimes it was oppressive, but I did it. Knowing when/where each tape was purchased also helps on getting 'warranted replacement', a considerable savings. Also knowing the number of hard/soft errors on a tape, and what tape drive allows for tracking tape drive errors.
It isn't fun, but needed in a big shop. Even in a small shop, I found going with (in my case) IBM brand was pretty easy to justify after having documentation on other vendor tapes. Even with them, tapes need to be cycled out for 'archival' use after a while. I hope this helps a little. ...
