Subject:   question on dump(8) and SCSI tape drive
Message-ID:  <3CDA045A.1060504@mac.com>

next in thread | raw e-mail | index | archive | help
I just installed a DDS-2 tape drive (Archive/Seagate Peregrine 
with HW compression) and want to do some backups. From what I can 
tell, a 120m tape should hold 4 Gb of uncompressed data and 8 Gb 
compressed. I'm puzzled why dump(8) wants 2 tapes to backup 77+ Mb 
of data (the / partition below) and 44% of a tape for /var (16 Mb).

   DUMP: estimated 77567 tape blocks on 1.99 tape(s).
