How do I crank up the performance of my backup system without changing everything?

One of the easiest ways to improve the performance of an existing backup and recovery environment is to replace slow tapes with high speed disks. And the easiest way to do that without making major modifications to the backup application is thru a VTL (Virtual Tape Library). A VTL is a combination of hardware, software, and disk storage that, as far as the backup application is concerned, appears to be an ATL (automated tape library). But since writting (and especially reading) data to disk is much faster than tape, the performance of backup (and especially recovery) operations goes thru the roof. One of our customers had a 24+ hour backup window with tape, which means he couldn't complete all his backups in any 24 hour period. After implmenting our VTL solution, his backup window shrunk to less than 10 hours.
