About restoring image-level backups

The image-level backups can be used to perform the following types of restores:
•
Recover a full virtual machine or specific virtual disks: You can use image-level backups to recover a full virtual machine to a previous known state or to restore one or more virtual disks for a virtual machine. This method is useful when there is data loss due to hardware failure, data corruption, or accidental deletion of virtual machine disk files. The virtual machine can be restored to the same or an alternate ESX Server Host.
•
Restore individual files and directories: You can use image-level backups to restore individual files and folders. This method is useful when there is data loss due to user errors, data corruption, or accidental deletion of files. The individual files and directories can be restored to a specified directory on the NetVault Backup Client.
 
 
*NOTE: To use an image-level backup for file-level restores, you must select the Perform File Level Indexing check box during backup.
File-level restores are supported on the following file systems:
•
Windows: NTFS
•
Linux and UNIX: EXT2, EXT3, EXT4
The Plug‑in for VMware also supports volumes managed by Logical Volume Manager (LVM) on Linux-based systems and Logical Disk Manager (LDM) on Windows-based systems as single or spanned disks.
The current version of the plug-in does not support Windows Server 2012 ReFS (Resilient File System) and Striped Disks.
•
Restore virtual machine disk and configuration files: You can use the image-level backups to restore the virtual machine disk and configuration files to a specified directory on the NetVault Backup Client. With these restored files, you can then recover a virtual machine with the same or modified settings using Virtual Infrastructure Client or any other utility that allows you to create a virtual machine using existing .vmdk files.

Restoring a full virtual machine or individual virtual disks

The procedure for recovering a full virtual machine or individual virtual disks from an image-level backup includes the step outlined in the following sections:
•
Prerequisites
•
Restoring data
•
Starting a virtual machine

Prerequisites

Before you start the restore procedure, verify that the following requirements are met:
•
If the virtual machine that you want to restore still exists on the host server, delete it.
•
Before you start the restore procedure on Windows 2008, clear the read-only attribute for the target disk. If you fail to do so, the restore job completes successfully, but no data is restored; when you power on the restored virtual machine, it fails to boot.
To clear the read-only attribute for the target disk
1
Start the diskpart utility and list the disks:
Diskpart
list disk
2
Select the target disk and display the disk details:
Select disk <X>
detail disk
3
If the read-only attribute is set to Yes, type:
attribute disk clear readonly
