First - look to insure you can 'go both ways'

On system everest (the one with the tape drive) do a
% rsh systemX uptime

as the user who will be running the script. Then go from systemX (the one to be backed up) to system Everest.
% rsh everest_backup uptime

If you get a response both ways of the output of the uptime command (or one of your favorites) then the next problem is permissions on the tape drive. If you get permission denied, then there is still a problem with trust between the servers. That is usually the problem - check your /etc/hosts.equiv files or appropriate rhost files for the user and servers.

It's possible that a regular user can't backup to the tape drive. Sign in as the user that will be running the job on the client. See if you can manually cpio to the tape drive on everest.

If this all works, then run the script manually. If it works - run in cron.

Post back results for all test.

tcopy

tcopy(1)							   User Commands							  tcopy(1)

NAME

       tcopy - copy a magnetic tape

SYNOPSIS

       tcopy source [destination]

DESCRIPTION

       The  tcopy  utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
       contents of a tape is that there are two tape marks at the end.

       When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files.  If a des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces the same output as it does when only scanning a tape.

       The tcopy utility requires the use of Berkeley-compatible device names. For example,

       example% tcopy /dev/rmt/1b /dev/rmt/2b
