Trying to use windows backup and bubba without succes?

[RealElwood]

I discovered that there's a backup function in Vista, seems pretty straight forward. But when i try to connect it to bubba it says the folder isn't accessable even though i prompt my login and passw.

Pretty much what i want to do is having the Vista PC backing up my new documents and new saved photos at each power-down.

What kind of file system is bubba running, when i read the help in Vista it says only NTFS, FAT or UDF is valid for backing up.
