If your really stuck, here is an idea..although not an answer to your question [sorry

]:
Install the IDE tape in an XP or 2k Pro box. If no SME PDC domain, turn it on on in server-manager and add the 2k/XP box to the domain (read the posts for this). Don't forget to create the root samba user with root password.
On SME configure samba smb.conf to share /home/e-smith/files (call this share smefiles)
Login on XP/2k as root in the domain.
Click: start/run: \\smeserver\smefiles This should give you access to the sme server file structure from /home/e-smith/files and all sub directories.
Use MS backup to backup this directory or select directories. This will allow you to restore select files on SME.
Use this inaddition to the backup to desktop.
Consider this an option to be able to backup all user data/email and have the ability to restore select files or folders from tape.
