      Hi,
  
      I was trying to make a backup of 4GB filesystem on a 4mm DAT (TLZ06)
  drive in an Alpha 3000 , but it gives me an message telling me that
  I'm going to need 6 4mm tapes for just 4GB!. I'm using the params
  showed in the man page for dump on OSF:
  
        ___________________________________________________
         Tape Device Density Size Size
                        (bpi) (feet) (1024-byte blocks)
         ___________________________________________________
       
         TLZ06 61000 2640 1887436
  
  
   /usr/sbin/ufsdump 0sduf 2640 61000 bainne:/dev/nrmt0h /home
  
  
   I guess I need another params to take more advantage of the tape
   (I'm using a DDS 120M tape),does anyone knows how to get the
   maximun benefit for this tape?
  
      thanks in advance
  
  -carlos
