How long to backup 5GB DB?

We are in the pilot phase of installing an application that uses an oracle database. The current estimate of the full database size is about 5GB. The pilot DB indexes are currently running at about 50% of the data size giving a full database guestimate (data+index) of 7 to 8 GBs.

Can someone please give me some idea (however rough) of:

1. How long it might take to backup this size of DB up to tape.
2. How long it might take to restore a DB of this size from tape back to disk.

Thanks for the help!
