Our testing, using Windows and a recent CPU etc, showed an average of about 
5GB/hour using disk or tape devices as the media.  The other way to do it is to 
go to a new server and use full backups to the new server, combined with 
exports for historical data if you can't just let it expire.  70GB in 4 hours 
is not going to happen (unless only 20GB of that 70 is occupied).
