Sal, No, not too simplistic. The environment you seek is quite feasible using file devclass volumes and built-in TSM features. What isn't feasible today is using this as the primary means to move all IT data offsite for disaster recovery, unless you don't have a lot of data or you have free bandwidth.
It's simply a matter of speed of the communication link and cost. While you can move a file hundreds of miles in seconds, you can't move 500GB of changed data hundreds of miles in seconds, minutes, or hours each day for a reasonable price with current technology. If the communications costs were free, we'd all do this. If you have a very small amount of changed data each day, this may be feasible for you.

With data on disk a simple copy can move it hundreds of miles in seconds or minutes. Can't a FILE device pool be used to recover data in an emergency? Am I making this too simplistic? Thanks, Sal
