jbackup script

The following script may be useful for sites wishing to execute a daily backup procedure.

#!/bin/ksh

# The following 3 lines setup the environment for the backup
# to run via Cron.
#
export JBCRELEASEDIR=/usr/jbc
export LD_LIBRARY_PATH=$JBCRELEASEDIR/lib:/usr/ccs/lib:/usr/lib
export PATH=$PATH:/usr/jbc/bin

# CD to a directory that has disk space to hold tempory files
# used during jbackup.
#
cd /tmp

# Echo the start of backup information.
#
echo Backup Started `date`
echo

# Perform the backup creating a Stat file, The stat file needs to be
# somewhere outside the backup path other wise jbackup will try to backup
# the same file that it is writing to. The file also needs to be pre-created
# or it will fail. This will also need to store the output from the
# backup in a convenient area of the disk.
# Modify the device name to match the one on your system. It needs to be
# a device with rewind.
# Also the -m needs to be changed to the correct media size for your tape
# device.

# then mail root with the error and also print a backup failed error
# message on the default printer. (add -d {printer name} to the lp
