Is it true that new backup solution doesn’t support tape drives?
Yes, that’s true because most Microsoft partners want to recommend disk backup to their customers, which is faster and more affordable. The new Windows Server 2008 backup technology uses block-based snapshot technology to make extremely fast, reliable backups that can be scheduled as frequently as every 30 minutes, with little performance impact on the server. This new technology requires backups to be run against an external disk. You can easily use a third-party tape backup solution with SBS 2008, if you prefer.
