How to Create a Bootable ESXi USB Drive
backup of VMWare using ghettoVCB.sh
You can back up VMware VM for free using ghettoVCB.sh script. Everything you need is here:
I was unable to download it directly to the the VMware server because wget v1.19 refused to download form https:// url.
Instead I downloaded the file to my Windows machine and used WinSCPPortable to upload the file to the server.
To extract the files do:
Go to ghettoVCB-master folder and make the scripts executable:
chmod +x ghettoVCB.sh
chmod +x ghettoVCB-restore.sh
Add a new NFS share as a datastore “backup”. This is where we are going to store the backup files.
Create some folders and configuration files. A typical way to execute the script is:
./ghettoVCB.sh -f vms_to_backup -g global_config/vm_global.conf
To schedule a cron job add the following line to /var/spool/cron/crontabs/root
0 0 * * 1-5 /scratch/ghettoVCB-master/ghettoVCB.sh -f /scratch/ghettoVCB-master/vms_to_backup -g /scratch/ghettoVCB-master/global_config/vm_global.conf > /vmfs/volumes/backup/ghettoVCB-backup-$(date +\%s).log
Then add the following to /etc/rc.local.d/local.sh
/bin/kill $(cat /var/run/crond.pid)
/bin/echo “0 0 * * 1-5 /scratch/ghettoVCB-master/ghettoVCB.sh -f /scratch/ghettoVCB-master/vms_to_backup -g /scratch/ghettoVCB-master/global_config/vm_global.conf > /vmfs/volumes/backup/ghettoVCB-backup-\$(date +\\%s).log” >> /var/spool/cron/crontabs/root
In order to allow the script to send emails you need to:
Step 1 – Create a file called /etc/vmware/firewall/email.xml with contains the following:
outbound tcp dst 25 true false
Step 2 – Reload the ESXi firewall by running the following ESXCLI command:
~ # esxcli network firewall refresh
Step 3 – Confirm that your email rule has been loaded by running the following ESXCLI command:
~ # esxcli network firewall ruleset list | grep email email true
Step 4 – Connect to your email server by using nc (netcat) by running the following command and specifying the IP Address/Port of your email server:
~ # nc 172.30.0.107 25 220 mail.primp-industries.com ESMTP Postfix
To perform a dry run restore do:
./ghettoVCB-restore.sh -c vms_to_restore -d 1
To perform a real restore do:
./ghettoVCB-restore.sh -c vms_to_restore

How to upgrade to VMware ESX 4.1 or VMware ESXi 4.1 using esxupdate

or download it from here.
Step 1. Connect to ESXi console and press the Alt+F1 key combination.
Step 2. Type unsupported and then press . Note that nothing will appear on the screen whilst you type this.
Step 3. When prompted enter in the Root password and press.
Step 4. You will now be presented with a prompt on the console. From this prompt type vi /etc/inetd.conf
Step 5. vi (the file editor) has now opened the inetd.conf file. Using the direction arrows scroll through the lines until you reach the line that has #ssh and remove the hash (ie: #). This is effectively un-commenting this line so that the ssh service can be started.
Step 6. Now that you have made this minor file you want to save this change and exit out of the editor (vi). To do this press the ESC key (to put vi back into Command Mode) and then type :wq *Note: If you want to exit without saving any changes to the file then just press the ESC key (Command Mode) and then type :q!.
Step 7. With the SSH service now un-commented from this file we want to restart the
