I agree. The original idea was to have ML2 in the VTS on virtual volumes. Then, once a day or two, we would take all the ML2 tapes in the VTS and stack them onto 3592 volumes using TapeCopy. At D.R. we would TapeCopy the ML2 data into the VTS at D.R. and use it for HSM. However, the complaint is that we have so much ML2 data that we could not actually test this in a 24 hour period. Oh, I did forget that we would disaster DUPLEX the ML2 tapes. One ML2 on site, on off-site. I would feel better with two offsite, but "oh, the cost!!!" I get the feeling that IT is just too expensive anymore. Another reason to go to Windows. They don't even pretend to be able to recover properly. Of at least, they've never proven it here. I wonder if we could hire a bunch of humans and keep everything on stone tablets. Stone tablets have a very long shelf life.
