I find it quite interesting in my travels how some folks are drinking the Kool-Aid that tape in general, and VTL in particular, are dead-end technologies. The argument is that tape sucks for backup, is hard to manage, and you need a LOT of it – so just backup to disk, dedupe, and be done with it. The argument against Virtual Tape Libraries is, why put in a technology that looks like tape if your goal is to get away from tape backup? Sounds like a good argument, right?
Except for some fairly important points.
