VMware Consolidated Backup Workflow | Types of Backups | Performing Image-Level Virtual Machine Backups

VMware Consolidated Backup Workflow

Before using Consolidated Backup, you need to configure and schedule a backup job for each virtual machine or a group of virtual machines.

At the scheduled time, the backup software starts the backup job on the VCB proxy. When the backup job is launched, the following steps take place:

1	The backup software calls the pre-backup script, which performs these tasks:

a	(Optional) Runs your custom pre-freeze script in the virtual machine.

The pre-freeze script prepares the critical software components in the virtual machine for a backup. See below Running Custom Quiescing Scripts.

b	Quiesces the virtual machine.

c	Puts the virtual machine into snapshot mode.

Changes to virtual disks are stored for later writing. The virtual machine can continue to operate during this process.

d	Unquiesces the virtual machine that was quiesced in Step b.

e	(Optional) Runs your custom post-thaw script in the virtual machine.

The post-thaw script reverses any changes made by the pre-freeze script in Step a.

f	Makes the virtual machine snapshot available to the third-party software:

•	For image-level virtual machine backups, see below Performing Image-Level Virtual Machine Backups.

•	For file-level backups of Microsoft Windows virtual machines, see below Performing File-Level Virtual Machine Backups.

2	The backup software performs an ordinary backup of the virtual machine snapshot moving the data to a backup medium. The virtual machine can continue to operate during this process.

3	The backup software calls the post-backup script, which performs the following tasks:

a	Unmounts the virtual machine snapshot from the backup proxy.

b	Takes the virtual machine out of snapshot mode, committing to disk any changes made while the machine was in snapshot mode.

Introduction

Today we are using computers for various activities, motor vehicles for traveling to places, and mobile phones for conversation. How many of us can claim the invention of micro-processor, a basic wheel, or the telegraph? Similarly, this book was not written overnight. The journey of this book goes many years back with many individuals to be thanked for.

To begin with, we want to thank all those interviewers who reject interviewees by saying they need to know ‘the key things’ regardless of having high grades in class. The whole concept of interview questions and answers revolves around knowing those ‘key things’.
