How to take Live-Backup of VMware(Esxi Server) VM host
Introduction–
ghettoVCB is a simple shell script which you can use to take backup of LIVE/ONLINE backup of Vm hosts/machines/servers on VMware ESXi-4.x Servers. It is a alternate solution of VCB (Vmware Comprehension Backup)
We need to copy this script on VMware ESXi servers. Please enable SSH on ESXi server and then copy this tool/script on the server.
Step 1) Download and Copy ghettoVCB Tool on Physical host of VM like host01 etc at following location
[root@localhost]# wget -c http://communities.vmware.com/servlet/JiveServlet/download/8760-71-63631/ghettoVCB.tar.gz
/var/src/ghettoVCB
[root@localhost]# tar xvfz ghettoVCB.tar.gz
[root@localhost]# ls ghettoVCB
arunb_vm_to_backup ghettoVCB.conf ghettoVCB.sh
[root@localhost]#
** I am copying ghettoVCB to host01 which is my VMware ESXi Server
[root@localhost]# scp -r ghettoVCB host01:/vmfs/volumes/datastore1/
Step 2) Then Login to Physical host of VM say host01
[root@localhost]# ssh host01
~ # ls /vmfs/volumes/datastore1/ghettoVCB
arunb_vm_to_backup arunb_vm_to_backup-temlate ghettoVCB.conf ghettoVCB.sh
~ #
Step 3) Please add VM you want to BACKUP (Live Backup)
* Open file in vi (for example I wanted to take backup of host01vm8)
~ # vi /vmfs/volumes/4e1e2374-4417303c-c9e5-00259037a1e1/ghettoVCB/arunb_vm_to_backup
~ # cat /vmfs/volumes/4e1e2374-4417303c-c9e5-00259037a1e1/ghettoVCB/arunb_vm_to_backup
host01vm8
~ #
Step 4) Start Backup in DRY-RUN Mode First ~
[root@localhost]# ssh host01
~ # cd /vmfs/volumes/datastore1/ghettoVCB/
/vmfs/volumes/4e1e2374-4417303c-c9e5-00259037a1e1/ghettoVCB # ls
arunb_vm_to_backup arunb_vm_to_backup-temlate ghettoVCB.conf ghettoVCB.sh
** DRY-RUN First –
/vmfs/volumes/4e1e2374-4417303c-c9e5-00259037a1e1/ghettoVCB # ./ghettoVCB.sh -g ./ghettoVCB.conf -f arunb_vm_to_backup -d dryrun

That’s it!!
NOTE – PLEASE CHECK BACKUP PATH (where do you want to TAKE BACKUP) in “ghettoVCB.conf”
