>I am currently running Win 2K and am going to upgrade to XP soon. I am using the native Backup application in Win 2k. Will the backup application in XP read tapes created with the Win 2K version?

I'm guessing that it will, based on the fact that it looks to be the same software, made by the same company, and the backup file has the same extension. It's just a SWAG, though. I don't have the equipment to try it.
