Access to TS1120's at the DR site is likewise a concern of mine. Most DR sites have numerous 3590's, so obtaining as many as you need probably isn't an issue. TS1120's are mooocho expensive and I don't expect DR sites are going to have many available (at least not initially, MAYBE over time). The systems I support are "low priority" in the grand scheme of things, and I wouldn't want to be told "Sorry, I know you are ready to go now and your systems have already been down for 7 days - but you won't be able to have access to any of our TS1120 drives until XYZ Group finishes with them, that'll be about 10 days from now....."!

On the hardware encryption: This would assume that your disaster recovery facility had those same encrypting tape drives in place, wouldn't it? It would limit your possible recovery sites considerably. And even if your DR vendor installed the same drives on one of their platforms, what if someone else declares before you, and is already in the shell that has your needed tape drives? -- .~.
