VMware vSphere Data Protection (VDP) – Part II (Backup)

In the first part of the series of articles related to VDP, we also introduced how it works, and this section explores how to back up vSphere Data Protection v.6.1.

In VDP, to create and edit a support, you can use the Backup bar in the Appliance for this software in the vSphere Web Client. In VDP, in addition to selecting virtual machines or certain VMDK files for backup, all virtual machine locations such as datacenters, clusters, and resources can also be selected for backup. When a virtual machine is added to a protected location, it is automatically retrieved from that backup. Similarly, when a virtual machine exits that location, it will no longer be in the maintenance phase. Restore Points are maintained in accordance with the Policy until the expiration date.

Support jobs can be scheduled on a daily, weekly or monthly basis, in which case, each job starts at its scheduled time and the program runs once a day.

The maintenance policy can be defined in a number of different ways; for example, backup files are kept for thirty days or until a certain date, even the ability to define a new policy and customize the maintenance policy.

Once an Job is created for backup, it can be edited or deleted. You can even copy a copy job exactly. Cloning can be useful, for example, if the Backup manager wants to simply duplicate an existing custom maintenance policy for a new virtual machine class.

The first backup of a virtual machine is due to the fact that all the data blocks that make up the virtual machine should be taken back; it may take some time. Next backups generally require less time because VDP uses CBT in vSphere.

Getting Backup from the App

VDP has the ability to back up and restore the Exchange Server, SQL Server, and SharePoint applications' databases. SQL Server clusters as well as database access groups (Database Availability Groups) on the Exchange server also include support. In the operating system of each virtual machine running in these programs, an agent is installed on the VDP program. You can also install these agents on physical machines to protect the databases of Exchange Server, SQL Server, and SharePoint applications. Agents provide the ability to back up and restore applications that are compatible with the application, and supports other options such as Full, Differential, and Incremental backup; Multi-Stream backup; and Database Log Management.

 Replication Data Backup

VDP can back up data between the VDP Appliance and the Replication, Avamar. This feature is especially useful in transferring offsite backups to secure and reliable data. Because back up data is duplicated both at source and destination, only the single parts of the backup data are retrieved. The replicated data is encrypted and compressed to be secured and minimizes network bandwidth usage. When creating a Job for Replication, you can define specific criteria for replication of the backup data.

Each client, virtual machine, and program can be selected for Replicate; specific types of Backup (such as weekly backups) can be selected and set a time limit for it.

Replication Job can be scheduled daily, weekly, or monthly. By default, the policy of storing backup data is the same as the backup data for the job that has been retrieved. You can, of course, define a different policy for backup replicated data. For example, perhaps the network administrator wants to keep back-up data as Local for thirty days and Replicated backup data to Offsite for 180 days.

There are several replication topology options in the VDP. Replication can be implemented with one-to-one or with a more robust topology, such as many-to-one. Backup data can also be provided as "Re-replicate." For example, as shown in the screenshot below, Backup is provided with Remote Office A virtual machines. Replication of these data is then backed up to the original datacenter and then replicated to the backup data from the main data center. Will be redirected to Remote Office B. As a result of this operation, backup data will be available in all three locations.

Recovery (Restore)

Using the Restore bar in VDP Appliance, you can restore a whole virtual machine. The network administrator can check the list of protected virtual machines and specify one or more restore points or restore points. Virtual disk drives can also be retrieved.

VDP delivers fast and efficient recovery using CBT. When retrieving a virtual machine to its original location, in addition to the Full Image recovery task, retrieval using CBT is also evaluated. VDP intelligently determines which method to perform virtual machine recovery operations is faster and chooses.

In addition to the above, the VDP can retrieve replicated backup data from virtual machines at destination and locally.

Here's a more precise scenario.

Suppose a VDP Appliance protects virtual machines in the original data center. Backup data by VDP from the main data center is replicated to the VDP in a Disaster Recovery Data Center. During an incident that occurs for the main data center, virtual machines, including VDPs, will be destroyed. In the next, when the main data center re-online, it creates a new VDP and connects to the VDP in the Disaster Recovery site. At this point, the VDP has the ability to retrieve back up data from the Disaster Recovery site and restore it to the main data center.

In the next section of the VDP articles series, we will describe the vSphere Data Protection vendor’s details on recovery details.
