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 drives: You can use image-level backups to recover a full virtual machine to a previous known state or to restore one or more virtual drives 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 VMware ESXi Server Host or VMware vCenter Server.
•
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 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 indexing is disabled by default.
File-level restores are supported on the following file systems:
•
Windows: NTFS
•
Linux and UNIX: EXT2, EXT3, EXT4, XFS v2, XFS v3
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 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 lets you create a virtual machine using existing “.vmdk” files.
•
Instant restore with continuous data protection (CDP) and QoreStor: If you use CDP for your VMware backups and QoreStor for your repository, you can recover data using the instant restore feature. QoreStor leverages remote database access (RDA) protocol and Linux network file sharing (NFS) to act as a temporary datastore to which NetVault mounts a backed-up image of a VMware virtual machine (VM), making the VM available in a matter of seconds. From here, you can confirm that the image contains all of the desired data and then migrate it to a vCenter host. For more information, see the NetVault Administrator's Guide and the QoreStor User Guide.

Restoring a full virtual machine or individual virtual drives

The procedure for recovering a full virtual machine or individual virtual drives from an image-level backup includes the steps 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:

•
When restoring individual virtual drives, the target virtual machine and virtual drives should exist in the inventory. If the virtual machine or virtual drives are unavailable, use the Rename option.
•
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 turn 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
