Module 10-3


Importance

Over time, your VMware vSphere™ environment might undergo changes to its hardware or software configuration. In addition, application data goes through constant change. From a manageability perspective, it is important to take regular backups of your vSphere environment.


Module 10-4


Module Objectives

Describe the strategy for backing up a host’s configuration data

Describe a strategy for backing up virtual machines

Describe solutions for backing up virtual machines

Use VMware Data Recovery to back up and restore a virtual machine


Module 10-5


Backup Solutions for Virtual Machines

VMware provides these solutions for backing up your virtual machines:

Third-party backup software that uses the VMware vStorage APIs for Data Protection

Data Recovery


Module 10-6


vStorage APIs for Data Protection

vStorage APIs for Data Protection:

Allows backup and recovery of entire virtual machine images across SAN storage or local area networks

Is an API that is directly integrated with backup tools from third-party vendors

Enables you to remove load from the host and consolidate backup load onto a central backup server

Protects virtual machines that use any type of storage supported by ESX/ESXi (Fibre Channel, iSCSI, NAS, or local storage)


Module 10-7


Data Recovery

Backup-and-recovery appliance:

Agentless, disk-based backup-and-recovery virtual appliance:• Linux-based

Based on the vStorage APIs for Data Protection

Integrated with VMware vCenter Server:

VMware vSphere Client plug-in

Supports up to ten appliances per vCenter Server instance:

Supports up to 100 virtual machines per appliance

Intended for small- to medium-sized environments


vCenter Server

Module 10-8


Installing and Configuring Data Recovery

1. Install the client plug-in.

2. Install the backup appliance.

3. Add a hard disk to the backup appliance.


Installation:

1. Power on the appliance and change the root password.

2. Configure network settings, and reboot the appliance if necessary.

3. Connect the appliance to vCenter Server.

Configuration:

Module 10-9


Creating a Backup Job

Use the client plug-in to create a backup job.

A backup job requires the following information:

Virtual machines to back up:

• Individual virtual machines, virtual machines in a datacenter, on a particular host, in a certain folder

Backup destination:

• Deduplication store or CIFS share

Backup window:

• Default window: every night Monday through Friday, any time on Saturday and Sunday

Retention policy (length of time that backups are preserved):

• Predefined (few, more, many) or custom

A maximum of eight backup jobs can run simultaneously.

Backup jobs can back up 100 virtual machines total.


Module 10-10


Restoring a Virtual Machine

When restoring a virtual machine, you can perform a restore rehearsal or an actual restore.

Restore to most recent backup rehearsal:

• A way to ensure that virtual machine backups are created correctly and that they can be successfully restore

Restore:

• Actual restore of a virtual machine to a selected previous state

Both types of restore jobs require:

Source selection:

• Virtual machines and virtual disks to restore

Destination selection:

• Original or different location of the virtual machine

Reconfiguration options:

• Whether to connect the network interface card (NIC), whether to power on the virtual machine


Module 10-11


Lab 17

In this lab, you will use Data Recovery to back up and recover a virtual machine.

1. Install the Data Recovery plug-in.

2. Modify the Data Recovery virtual appliance.

3. Do the initial setup of the Data Recovery appliance.

4. Create a backup job.

5. Create a restore job.

6. Prepare for the next lab.

Describe a strategy for backing up virtual machines

Describe solutions for backing up virtual machines

Use Data Recovery to back up and restore a virtual machine


Module 10-13


Key Points

Data Recovery is an agentless, Linux-based virtual appliance used for backing up and recovering virtual machines.

Data Recovery uses deduplication store technology to make efficient use of the backup storage.

Data can be restored per virtual machine, per virtual disk, or per file.
