Hi Sun Managers,

        Thanks to everyone. The common points are:
1, usr s option with restore command. the n follows s means the dump session
   number. ( Actually, I tried this option, but mistakenly thought it is
   the number of real files need to skip, so I tried some large number, and
   of course, it didn't work).
2, use mt to forwind tape to the beginning of dump session to be restored.
   mt -f /dev/rst? fsf n
   this n is the session number-1.
   and then use restore command.

I used the first method and it works!

The original posting is :
> We are using dump command to backup some directories on one tape.
> With the no rewind option, the command like:
> /usr/etc/dump 0bdsfu 64 1000 700 /dev/nrst2 directory_1
> /usr/etc/dump 0bdsfu 64 1000 700 /dev/nrst2 directory_2
> /usr/etc/dump 0bdsfu 64 1000 700 /dev/nrst2 directory_3

> It looks like work fine, with one sesseion follwing another. But when we
> check the backup, the files in directory_2 and directory_3 never show up,
> no matter we use restore in interactive mode or other option. Only the
> directory_1 show up. My question is :
> How to access the files in other_than_the_first backup session on the tape
> by using command restore?
> Are there better way to restore the files on a multiple backup sessions tapes?
> We run sunos4.1.2 and ow3 on SS2.
