How much of that 80Gb changes, and how often? If the data is mainly 
static then there's no point in backing up all of it every time. You may 
find that the changes to the data can be backed up over the Internet, in 
which case tape is probably not the best option.

If it's only 80Gb then you should be using disk backup in addition to 
tape anyway. Put a 250Gb disk in and keep multiple generations of 
compressed archives. The commonest requirement is to restore a file that 
someone accidentally deleted, that's far easier to do from disk.

Don't forget that you always need offsite backups in addition to 
whatever you use onsite. Local disk backups are great but they won't 
help if the site burns down or is unavailable because it's behind a 
police cordon.
