======How to make backups in VMware using ghettoVCB.sh and crontab======
=====Install ghettoVCB=====
Download latest files from github:
[[https://github.com/lamw/ghettoVCB]]
Put the files on a datastore. I use datastore backup (/vmfs/volumes/backup), which is an NFS mount.
I have put the original scripts in /vmfs/volumes/backup/bin. I have create my own cron script to put the backup files in the necessary directories.

From download machine:
  scp ghettoVCB-master.zip root@supermicro1.mngt.bh.helux.nl:/vmfs/volumes/backup
From hypervisor:
  cd /vmfs/volumes/backup
  unzip ghettoVCB-master.zip
  mv ghettoVCB-master bin
  mkdir log
  mkdir data
  mkdir conf

<code - /vmfs/volumes/backup/cron-ghettoVCB.sh>
#!/bin/sh
BACKUPDIR=/vmfs/volumes/backup
BINDIR=$BACKUPDIR/bin
CONFDIR=$BACKUPDIR/conf
LOGDIR=$BACKUPDIR/log
DATE=$(date +%d-%m-%Y-%H-%M)
HOSTNAME=$(hostname)

case $(hostname -d) in
  mngt.bh.helux.nl) DOMAIN=bh ;;
  mngt.rtd.helux.nl) DOMAIN=rtd ;;
  mngt.ams.helux.nl) DOMAIN=ams ;;
  *) DOMAIN=unknown ;;
esac

$BINDIR/ghettoVCB.sh -a -g $CONFDIR/ghettoVCB-$DOMAIN.conf -l $LOGDIR/$HOSTNAME-$DATE.log >/dev/null 2>&1

exit 0
</code>

=====Configure ghettoVCB=====
I use different configs for each datacenter. I have hypervisors in 3 datacenters.

=====Configure crontab=====
Add the following on each ESXi hypervisor. The notation of the crontab is as follows:
  #min hour day mon dow command

using the following config it means. run on 1:00 on sunday (day 0)

<code - /etc/rc.local.d/local.sh>
.
.
/bin/kill $(cat /var/run/crond.pid)
/bin/echo "0    1    *   *   0   /vmfs/volumes/backup/cron-ghettoVCB.sh" >> /var/spool/cron/crontabs/root
crond
exit 0
</code>

after that run it for 1 time only!

  /etc/rc.local.d/local.sh

make it persistent

  /sbin/auto-backup.sh

=====Use Bacula to backup the NFS share=====
We only backup vms backupped with status OK. So I use a script before I run the Bacula job.
This script is the same NFS share on Linux as a datastore on the hypervisor. In this situation the NFS share is mounted on /mnt/synology/volume1/vmware/backup on the Linux machine we are going to backup using Bacula.

<code - run-before-bacula.sh>
#!/bin/bash
BACKUPDIR=/mnt/synology/volume1/vmware/backup
STATUSOK=STATUS.ok
STATUSWARN=STATUS.warn
TEMPDIR=$BACKUPDIR/temp

case $1 in
  bh) DATADIR=$BACKUPDIR/data/bergschenhoek ;;
  rtd) DATADIR=$BACKUPDIR/data/rotterdam ;;
  ams) DATADIR=$BACKUPDIR/data/amsterdam ;;
  *) echo "usage $0 <bh|rtd|ams>"
     exit 1 ;;
esac
 
rm -rf $TEMPDIR/*

for fulldir in $(find $DATADIR -name $STATUSOK -exec dirname {} \; -o -name $STATUSWARN -exec dirname {} \; ); do
  DIR=$(basename $fulldir)
  VMNAME=$(echo $fulldir | sed  "s|$DATADIR||" | cut -d'/' -f2)
  if [ ! -d $TEMPDIR/$VMNAME ]; then
    mkdir $TEMPDIR/$VMNAME
  fi
  mv $fulldir $TEMPDIR/$VMNAME
done

rm -rf $DATADIR/*
mv $TEMPDIR/* $DATADIR
