Very Computer

Greetings everyone.

Our library just recently purchased a new Sun workstation.  I'm
currently working on the backup cron job.  The vendor that sold
us the Sun will only support backups using ufsdump.  I wrote the
cron jobs and set the crontab file and everything is running
fine.

What I want is to create a series of log files to report the
backup results.  I know that ufsdump has three exit status
values: 0 (normal), 1 (error), and 3 (abort).  What I want to
know is if it's possible to 1) echo the screen output to another
file for review (in case of errors or aborts) and 2) if a notice
can be sent to one of three files based on the exit status (i.e.
bu.log, bu.err, bu.abort)?  If both of these are possible, what
do I need to do to make it so.

Thanks in advance.

The easy way to create a log file of the ufsdump command is to redirect it
into a file  (ufsdump .......  > /path_to_file/file_name).

If you want to "separate" level 0, 1 & 3, you can do as follow (it is what
I'm doing) :

    I create a script that's doing my ufsdump. In my crontab, the script is
executing and I redirect the answer into a mail  to the sysadmin group (0 7
* * * name_of_my_script 2>&1 | mailx -s "Ufsdump" sysadmin). Now, to
separate the three level, I use Microsoft Outlook to inspect the content of
the mail.

    For me, it's working very well
hope I helped you

Sure, this can be done with simple Bourne shell programming:

        #! /bin/sh

        TAPE=/dev/rmt/0n
        export TAPE

        logdir=/var/adm/log/bu  # or whatever

        level=0
        blockf=64

        for fs in / /var /usr /opt /home /whatever/else
        do

                mt status
                echo

                ufsdump "$level"ubf "$blockf" "$TAPE" "$fs"

                case $? in
                0) logfile=normal ;;
                1) logfile=error ;;
                3) logfile=abort ;;
                *) logfile=other ;;
                esac

                echo

                logfile="$logdir/$logfile"

                echo "level $level filesystem $filesystem date `date`" >> $logfile"
        done

        mt status

Sending the output elsewhere can of course be done with redirection,
and maybe the "tee" command.  You'd do the ufsdump command something
like this:

        ufsdump 0ubf 64 /dev/rmt/0n /file/system 2>&1 | tee mylogfile

Or heck, run your entire script (or your entire main loop) into a
"tee logfile" command.  Put it in cron if you want:

        0 3 * * * /var/adm/mybackupscript 2>&1 | tee -a /var/adm/log/backuplog

Hope that helps.
