Description

The following script, executed in root's crontab, is an example of offline vdisk files bakups. The steps are:

clean shutdown of a Tru64 system with hostname = pluto. For more see: VM management - Create/Edit guest stop script
vdisk file backup in a zip file
restart of the Tru64 system (if it was up before the shutdown)

Script

/charon/charon_backup_pluto

#!/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}"

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
