Here is what I did. This will have to work for me until the clone feature
makes it into a released version.
In the job def I have:
Run After Job = "/root/bacula_postexec.sh %v"
The %v gets expanded to the volume name.
Here is the shell script. It is simple and gets the job done. I could not
get bcopy to work. With this way you will have to restore the volume to the
disk before you can use it.
------------------------------------------------------
#!/bin/bash
# Take the volume name from the command line
disk_volume=$1
# Take the week number from a file (we have 3 weeks of tapes)
weeknum=`cat /root/weeknum`
# Take the day of the week for the tape label
day=`date -d yesterday +%a|tr '[A-Z]' '[a-z]'`
cd /etc/bacula
# Rewind the tape -- we will have every job in the volume and don't need more
mt rewind
# Write the volume to the tape with a label
tar cvf /dev/nst0 -V oink-$day-$weeknum /backup/$disk_volume
# This lets me know the copy finished
mt offline
# Increment the weeknum at the end of the week
if [ $weekday='sat' ]
then
let weeknum=$weeknum+1
if [ $weeknum > 3 ]
then
weeknum=1
fi
echo $weeknum > /root/weeknum
fi
