I agree... anybody else thing this would be a good feature request?

If you're taking 26 hrs to back up the data are you sure you can stand 
the 48 or more hours of downtime you're likely to experience in the 
event of a big failure?  I'd think that faster tape drives, and/or a 
faster spool filesystem may be in order.  In the mean time, have you 
considered breaking the data down into separate jobs so none of them 
take so long individually?  Also, this has the added benefit that if 
there is a problem in the middle and the backup dies (server or network 
instability, or even just a tape error) you probably won't have to 
re-backup as much.
