How to Easily Backup ESXi VM with GhettoVCB Scripts?

VMware vSphere is widely adopted by enterprises to deploy virtual environments. However, to protect the virtual environments, a backup solution is needed to guarantee business continuity. For example, IT administrators can use the free backup script to backup ESXi VMs.

What is ghettoVCB.sh?

The "ghettoVCB.sh" script is primarily designed for backup and restore purposes in VMWare ESXi 3.x, 4.x, 5.x, 6.x, 7.x & 8.x. It is similar to VMware's VCB (VMware Consolidated Backup) tool for performing backups. The workflow of ghettoVCB.sh involves taking a snapshot of the virtual machine, performing the backup, and then deleting the snapshot once the backup is completed. The script's notable feature is its ability to perform backups while the virtual machine is online, without the need for a shutdown.

Of course, except for ghettoVCB, you can also use PowerShell script to backup ESXi VMs.

As a simple backup solution for ESXi VM, ghettoVCB can only create full backup every time, so if you would like to backup only the delta data or in other words, create incremental backup or differential backup, you need other backup solutions like Vinchin Backup & Recovery.

Pre-configuration

You need to enable SSH on the ESXi host in vCenter and upload ghettoVCB to the ESXi server.

1. Enable SSH:

   1) Login to vCenter

   2) Select the ESXi host

   3) Select Configure on the right

   4) Expand System

   5) Select Services

   6) Select SSH

   7) Click START to enable SSH on the host

2. Upload ghettoVCB:

   1) Download ghettoVCB from GitHub

   2) Login to vCenter

   3) Select the ESXi host

   4) Select Datastores on the right

   5) Select a datastore

   6) Click UPLOAD FILES to upload the zipped folder

Installing ghettoVCB

Since you have done the preparations, just untar the folder

1. Connect to the ESXi host using an SSH client

2. Navigate to the datastore where you uploaded the ghettoVCB files.

cd /vmfs/volumes/datastore_name

3. Extract the ghettoVCB archive

tar -zxvf ghettoVCB-archive.tar.gz

How to backup ESXi VM with ghettoVCB.sh?

Usage Example:

./ghettoVCB.sh -f [VM_BACKUP_UP_LIST] -c [VM_CONFIG_DIR] -l [LOG_FILE] -d [DEBUG_LEVEL] -g [GLOBAL_CONF] -e [VM_EXCLUSION_LIST]

OPTIONS:

-a   Backup all VMs on the host

-f    List of VMs to backup  

-c    VM configuration directory for VM backups

-g    Path to global ghettoVCB configuration file

-l     File to output logging

-d    Debug level [info|debug|dryrun] (default: info)

There are some common commands for different backup plans:

Backup VMs stored in a list:

./ghettoVCB.sh -f vms_to_backup

Backup all VMs residing on this host:

./ghettoVCB.sh -a

Backup all VMs residing on this host except for the VMs in the exclusion list:

./ghettoVCB.sh -a -e vm_exclusion_list

Backup VMs based on specific configurations located in the directory:

./ghettoVCB.sh -f vms_to_backup -c vm_backup_configs

Backup VMs using the global ghettoVCB configuration file:

./ghettoVCB.sh -f vms_to_backup -g /global/ghettoVCB.conf

The output will log to /tmp/ghettoVCB.log (consider logging to local or remote datastore to persist logs)

./ghettoVCB.sh -f vms_to_backup -l /vmfs/volume/local-storage/ghettoVCB.log

Dry run (no backup will take place):

./ghettoVCB.sh -f vms_to_backup -d dryrun

After you make a VM backup with ghettovcb.sh, you can use ghettovcb-restore.sh to restore the ESXi VM when needed.

Debugging and test

After understanding the relevant parameters and settings, let's implement a simple example.

1. Establish a list for VM

~ # vi vms_to_backup
# Add the VM names

2. Debugging

It is quite useful for troubleshooting.

~ # ./ghettoVCB.sh -f vms_to_backup -d debug

3. Dry run testing

The main purpose is to test the backup first to see if there are any issues. Dryrun mode will not generate backup files.

~ # ./ghettoVCB.sh -f vms_to_backup -d dryrun
