NTbackup (XP Pro) compression levels?

One of our users is using NTBackup to back up all his data to a 120gb USB2.0 external HDD. He has about 26gb of Music in his iTunes folder (included in the backup set) and 4-5 GB of other data.

He has run a few backups now, and they all are around 3gb when we look at the disk. We can open up NTbackup and browse the backed up files, tried restoring a few - everything seems to be there. Is this possible? I didn't think so, but I can't explain what is going on.
 
you may be right there cubby... still, why would I be able to restore files if the backup was not complete. Or is it just *showing* me the smaller file size but it's really taking up much more room on the disk?
 
Try restoring the whole thing or verifying the backup, I suppose it's possible only part of the backup actually finished.
 
I think it's splitting it into 3GB files to avoid problems with the 4GB file limit on FAT drives.

Not sure how to get it though.
 
I wonder if there would be any issues with nt backup if you backed up into a folder whos advanced attributes was checked compressed?

Nope, NTBackup will backup the attributes; if you restore to a NTFS volume the files are restored as compressed.
