Description
The following script, executed in root's crontab, is an example of offline vdisk files bakups. The steps are:
Script
#!/bin/bash
WASACT=`systemctl is-active charon_pluto 2>/dev/null`
if test "${WASACT}" = "active"
then
echo "`date +'%Y%m%d:%H%M%S'` Stopping charon_pluto service"
systemctl stop charon_pluto
while test 1
do
echo "`date +'%Y%m%d:%H%M%S'` Waiting 60 seconds for full stop..."
sleep 60
systemctl -q is-active charon_pluto
test $? -eq 3 && break
done
fi
echo "`date +'%Y%m%d:%H%M%S'` Service status:"
systemctl -l status charon_pluto
echo "`date +'%Y%m%d:%H%M%S'` Zipping /charon/disks/pluto_tru64.vdisk file"
zip -j /charon/backups/pluto_tru64.vdisk.`date +%a`.zip /charon/disks/pluto_tru64.vdisk
RET=$?
if test "${WASACT}" = "active"
then
echo "`date +'%Y%m%d:%H%M%S'` Service was active, restarting..."
systemctl start charon_pluto
sleep 30
echo "`date +'%Y%m%d:%H%M%S'` Service status:"
systemctl -l status charon_pluto
fi
if test ${RET:-0} -eq 0
then
echo "`date +'%Y%m%d:%H%M%S'` Backup completion: success"
else
echo "`date +'%Y%m%d:%H%M%S'` Backup completion: failure ${RET}"
fi
exit
Crontab entry
#=== Stop the charon_pluto service if it was running, backup the vdisk file and restart (if it was running)
00 20 * * * /charon/charon_backup_pluto >/charon/charon_backup_pluto.log 2>&1

In the example above, the script will run everyday at 20:00 and will log the output to the /charon/charon_backup_pluto.log file
