I'm glad to see more formal products using disk for backup are finally starting to hit the market. Anyone who has had to deal with backup in situations where restore/backup time matters, knows that disk is the only reasonable way to go. Tape is slow, and you need an admin around to coddle those nice big tape librarys that jam and need to be cleaned all the time... Its nice to see formal products are starting to appear to support the backup methodology that clued admins have been following for several years now.
