Crontab - URGENT pls

I put

30 2 * * * /usr/bin/tar cvf /dev/rct0 /u/csa/*

in my crontab file (SCO5) but I want to be absolutely sure that the backup job finishes successfully. I know that whenever cron cannot execute a command sends an e-mail to root with the error code and/or an explanation of the problem.

What I want is a way to display a message on screen so that I (or anyone else, in case I'm missing) can see it in the morning and check the backup status (completed successfully/not completed successfully).

Unfortunately, even though there is no mail about tar on root, I've the suspicion that the tar command is not executed. (To tell, I changed the time from 2:30, to 8:00 and nothing happened.)

Any help on that?

ATRUN(8)						    BSD System Manager's Manual 						  ATRUN(8)

NAME
atrun -- run jobs queued for later execution SYNOPSIS
atrun [-l load_avg] [-d] DESCRIPTION
atrun runs jobs queued by at(1). Root's crontab(5) must contain the line: */10 * * * * root /usr/libexec/atrun so that atrun(8) gets called every ten minutes. At every invocation, every job in lowercase queues whose starting time has passed is started. A maximum of one batch job (denoted by upper- case queues) is started each time atrun is invoked. OPTIONS
-l load_avg Specifies a limiting load factor, over which batch jobs should not be run, instead of the compiled-in value of 1.5. -d Debug; print error messages to standard error instead of using syslog(3). WARNINGS
For atrun to work, you have to start up a cron(8) daemon. FILES
/var/at/spool Directory containing output spool files /var/at/jobs Directory containing job files SEE ALSO
at(1), crontab(1), syslog(3), crontab(5), cron(8) AUTHORS
Thomas Koenig <ig25@rz.uni-karlsruhe.de> BUGS
The functionality of atrun should be merged into cron(8). BSD
