NTBackup file compression

I am using NTbackup under windows 2000 server and I was wondering how I
can tell if file compression is being used in my backups. I have the
option selected to "use file compression if available" (not sure if
that is exact wording), however I have not had to go back to tape to
check the format of the files in backup.

Is there a way to tell if the files are being compessed?

If your tape capacity is 20 GBytes then you should attempt to back
up 25 GBytes. You can do this by creating 5 files at 5 GBytes each,
using this command:

fsutil.exe file createnew 1.bin 5000000000
