have you enabled hardware/software compression?

There is a compress option in the advanced backup options

From the Backup helpfile

"To set advanced backup options

Open Backup.

Click the Backup tab and select the files and folders you want to back
up.

Click Start Backup.

On the Backup Job Information dialog box, click Advanced.

Set the advanced backup options you want, and then click OK. See the
Notes section for a description of each option.

Notes

To start Backup, click Start, point to Programs, point to Accessories,
point to System Tools, and then click Backup.

Choosing Back up data that is in Remote Storage backs up data that has
been designated for Remote Storage. If you select this option, Remote
Storage placeholder files are backed up. If you do not select this
option, Remote Storage placeholder files are not backed up. You can
restore Remote Storage data only to an NTFS volume that is used in
Windows 2000.

Choosing Verify data after backup verifies that the backed-up data is
exactly the same as the original data. This could substantially increase
the time it takes to perform a backup.

Choosing If possible, compress the backup data to save space compresses
the data you are backing up so you can save more data on a tape.
Usually, only tape drives have the ability to compress data. If this
option is disabled, you do not have a tape drive on your computer or
your tape drive cannot compress data.
Choosing Automatically back up system protected files with the System
State backs up all of the system files that are in your systemroot
directory in addition to the boot files that are included with the
System State data. This option will substantially increase the size of
your backup job. For example, if you choose this option on Windows 2000
Professional, it will add over 200 megabytes to the size of your backup
job.

Choosing a backup type in Backup Type determines how your data is backed
up. Backup types include: copy, daily, differential, incremental, and
normal. "

You may find your tapes are 20/40 gb which means they hold 20 gb
uncompressed and 40 gb compressed (in a perfect world). However average
compression is rarely achieved so a 25 to 30 gb is a better estimate ...
ie you'll be a long way short if you have 45gb of data.

In addition to what Steve P said about the tape size, it's posible that
much of the data on the drive may already be compressed also. You may
just have to adjust the number of folders backed up to fit your tapes.
