LARGE backup query

I have an Oracle database running on an HP 9000 under HP-UX 10.0. Currently, this is reasonably small (~ 1.5 gigabytes), but it is expected to grow to over 60 gigabytes. How do I do backups? The system currently has 3 tape drives attached to it, each with a 4-gig capacity.

If someone has experience with backing up something like this, I would dearly like to know.

Thanks,
