DLT backup

Ziv!

Na sihtu uporabljamo DLT40 masino za backup. Na skatli od traku
pise DLTtape IV, karkoli ze naj bi to pomenilo. Od 'pamtiveka'
oseba, ki to pocne, spusca komando (gre za SunOS)

/usr/sbin/ufsdump 4ucf /dev/rmt/0c /

Za dump level (v tem primeru 4) mi je jasno, prav tako tudi
za zastavici u --> update dump record in /etc/dumpdates in 
f --> dump file (v tem primeru /)

Za zastavico c --> cartridge pa mi ni niti malo jasno kaj naj
bi uredila. V manu je sledece 

    c              Cartridge.  Set the  defaults  for  cartridge
                    instead of the standard half-inch reel.  This
                    sets the density to 1000BPI and the  blocking
                    factor  to  126.  Since ufsdump can automati-
                    cally  detect  the  end-of-media,  only   the
                    blocking  parameter  normally  has an effect.
                    When  cartridge  tapes  are  used,  and  this
                    option   is   not   specified,  ufsdump  will
                    slightly miscompute the size of the tape.  If
                    the  b,  d, s or t options are specified with
                    this option, their values will  override  the
                    defaults set by this option.

Zgoraj omenjeni trak (DLTtape IV) je 0.5 incen. Na skatli se pise,
da je dol 1828 ft / 557 m nic pa o gostoti in blocking factorju.

Ali sploh prav uporabljamo to zastavico?

Hvala za pomoc in lp, Gregor
