NetVault Bare Metal Recovery 10.5 - User Guide for Plug-ins

Introducing Dell™ NetVault™ Bare Metal Recovery Plug-ins Deploying NetVault Bare Metal Recovery Using the Plug-in Offline Client Using Plug-in Live Client for Windows® Using Plug-in Live Client for Linux® NetVault Bare Metal Recovery physical-to-virtual recovery Troubleshooting

Booting the NetVault Bare Metal Recovery Client from a LiveCD

If you are booting the NetVault Bare Metal Recovery Client from a LiveCD, perform the following procedure. If you are booting the NetVault Bare Metal Recovery Client from a standard VaultOS CD, proceed to Booting the NetVault Bare Metal Recovery Client with the Windows® PE-based Plug-in Offline Client.
The following items are required for this procedure:
•
A LiveCD containing the desired OS.
Note the following important points:
•
The LiveCD must mount the loop-back device to perform backup and restore with NetVault Backup.
•
Some LiveCDs automatically mount all partitions for devices, which can lead to restore failure if the file system is mounted before a backup or restore job. If you boot with a LiveCD, ensure that the file system is unmounted before performing a backup or restore.
•
Some LiveCDs automatically use the swap partition for swap operations, which can lead to restore failure if the swap partition is used before a backup or restore job. If you boot with a LiveCD, ensure that the LiveCD does not use the swap partition before performing a backup or restore.
•
A Rescue device (see Creating a rescue device for use with a LiveCD).
•
A USB port (for a Rescue USB device) that uses the 2.x protocol or earlier, or a secondary CD-ROM drive (for a Rescue CD) on the target system. (If the drive is connected through a USB port, it must use USB 2.x protocol or earlier).
•
If you are using a Rescue CD, you need two CD-ROM drives on the target system — one for the LiveCD and one for the Rescue CD. (If connected through USB ports, the drives must use the USB 2.x protocol or earlier.)
To boot the client:
1
Insert the LiveCD in the CD-ROM drive (if connected through a USB port, the port must use the 2.x protocol or earlier) on the target system, and reboot the machine.
2
After the OS starts, plug in the USB device (2.x protocol or earlier) or load the Rescue CD.
Usually, the LiveCD automatically mounts the USB/CD drive and shows an icon on the desktop.
3
If the LiveCD automatically mounted the USB/CD drive, use the “mount -l” command to find the path where the device is mounted.
Example:
# mount -l
...
/dev/sdb1 on /media/disk type ext2 (rw,nosuid,nodev)
4
If the LiveCD does not automatically mount the USB drive, mount it manually:
 
* 
NOTE: Follow the same procedure to use a Rescue CD by mounting a CD instead of a USB device.
a
Use the “ls -l /dev/disk/by-id/usb*” command to find the USB devices on the system.
Example:
# ls -l /dev/disk/by-id/usb*
root 9 2007-09-26 8:16 /dev/disk/by-id/usb-JetFl -> ../../sdb
root 10 2007-09-26 8:16 /dev/disk/by-id/usb-JetFl-part1_-> ../../sdb1
root 10 2007-09-26 8:16 /dev/disk/by-id/usb-JetFl-part2 -> ../../sdb2
b
Mount the first partition on the device.
Example:
# mount /dev/sdb1 /mnt/usb
5
To start drdaemon, run the “vaultdr_client.sh” command.
Example:
# cd /mnt/usb
# sh vaultdr_client.sh
6
If you configured NetVault Bare Metal Recovery to use a port other than the default “10000,” exit the NetVault Bare Metal Recovery Daemon dialog box, and enter the new port number manually.
a
To exit the NetVault Bare Metal Recovery Daemon dialog box, press <Ctrl+C>.
b
At the command prompt, type the following command, and press Enter:
drdaemon -p port_number
where port_number is the port you specified in Adding a NetVault Bare Metal Recovery Client to the Plug-in Server or Editing an existing NetVault Bare Metal Recovery Client.
 
* 
NOTE: If you want to restart NetVault Bare Metal Recovery Daemon from the command prompt without changing the port number, type drdaemon and press Enter.
7
If you want to enable multipath support, type the following at a command prompt, and press Enter:
drdaemon -o mpath
 
* 
NOTE: You can enter the -o mpath and -p port_number options together.

Backing up data with Plug-in Offline Client

The Plug-in Server lets you back up full systems. In addition, the plug-in provides detailed backup capabilities that let you select individual disk partitions for backup. This plug-in includes the following items:
•
OS
•
Applications
•
Specific User Information
From the NetVault Backup Selections page, you can select the following Plug-in Server items for backup:
•
Disk Partitions: All (or individual) partitions can be selected for backup.
•
Mounted Volumes (Linux® and UNIX®): All of which are backed up as individual partitions.
 
* 
NOTE: The Master Boot Record (MBR) and the Partition Table items are backed up automatically when a partition (all or individual) is backed up using the Plug-in Server. Therefore, these items are not available to select for a backup.
Prerequisites
Before initiating a backup with the Plug-in Server, review the following sections for details on prerequisites that must be met.
 
* 
WARNING:Even if there is no difference between the system devices in a backup and a restore, the order of the disks might be different. If the restored data is started without performing a rename, any data that exists on the disks is lost. To compare the information of physical disk at backup and restore, note the Disk Geometry and Device Size at backup. For more information, see Performing a restore in which Disk Numbers are different from the backup.
Booting the NetVault Bare Metal Recovery Client with Plug-in Offline Client
You must boot the target NetVault Bare Metal Recovery Client with the Plug-in Offline Client to prepare it for the backup. To complete the boot process, review the steps in Booting with Plug-in Offline Client.
Verifying Disk Geometry and Device Size
Before backing up any portion of a NetVault Bare Metal Recovery Client’s hard drive, Dell recommends that you note the Disk Size and the Disk Geometry of the selected drive. If these items are not accounted for, a restore might fail.
Example of how to note the Drive Disk Size and Disk Geometry
A Client drive is divided into three partitions. The primary partition is 10 gigabytes (GB), the first logical partition is 7GB, and the second partition is 3GB. A backup of the first logical partition is performed with the Plug-in Server. On restore of the system after a hard drive crash, if the first logical partition was restored, you need to restore it to the proper partition (the first logical partition), or the restore fails.
To verify the geometry and size:
1
With the NetVault Bare Metal Recovery Client booted using Plug-in Offline Client (as outlined in Booting a NetVault Bare Metal Recovery Client with Plug-in Offline Client), access the NetVault Backup Server, and start the NetVault Backup WebUI.
2
In the Navigation pane, click Create Backup Job.
3
Next to the Selections list, click Create New.
4
On the NetVault Backup Selections page, double-click the NetVault Backup Server (the system containing the Plug-in Server) to open it.
5
Double-click the applicable NetVault Bare Metal Recovery Client displayed under the plug-in to reveal the disks contained within.
6
To determine the Disk Geometry, select the applicable disk, and then select Disk Geometry from the Actions list.
The Device Geometry dialog box displays details about the partition structure of the selected disk.
•
Partitions: Each individual partition is listed here by number and the partition type.
•
Active: Displays the current state of the partition (“Yes” or “No”).
•
Start Cyl: Displays the origination point (cylinder) for the various partitions.
•
End Cyl: Displays the partition’s endpoint (cylinder).
•
Size: Displays the size of each partition.
•
Type: Displays the type of partition.
7
With this information noted, click OK.
8
To determine the overall size of a disk, select the applicable disk, and select Disk Size from the Actions list.
The Device Size dialog box displays details about the size of the selected disk.
•
Device: The number and type of the disk.
•
Size: The size of the selected disk.
9
With this information noted, click OK.

Backing up data

Before performing a NetVault Bare Metal Recovery backup, consider the following important points:
•
The NetVault Bare Metal Recovery Client machine must be booted with the Plug-in Offline Client software before each operation of the Plug-in Server (backup or restore). If this procedure is not completed correctly, the NetVault Bare Metal Recovery Client is inaccessible from the NetVault Backup Server. For details on this process, see Booting a NetVault Bare Metal Recovery Client with Plug-in Offline Client.
•
When Disk Raw Mode is selected, not only is the disk in use backed up, but the entire disk is as well. For example, if 6GB are in use on a 30GB partition, 30GB of media is used to back up the disk. Only use the Disk Raw Mode option when a complete hard drive is selected for a Plug-in Server backup (that is, not an individual partition).
•
Dynamic disks must be backed up by using Disk Raw Mode to maintain partition information.
•
Plug-in Offline Client does not support DR backup spanning multiple libraries. Attempting to restore a backup job that spans multiple libraries fails.
You are now ready to perform a backup of the NetVault Backup Server. The procedure for performing backups includes the steps outlined in the following sections:
•
Selecting data for a backup
•
Setting backup options
•
Finalizing and submitting the job

Selecting data for a backup

You must use sets (Backup Selection Set, Backup Options Set, Schedule Set, Target Set, and Advanced Options Set) to create a backup job. For more information, see the Dell NetVault Backup Administrator’s Guide.
To create a Backup Selection Set:
1
With the NetVault Bare Metal Recovery Client booted with Plug-in Offline Client, access the NetVault Backup Server, and start the NetVault Backup WebUI.
2
In the Navigation pane, click Create Backup Job.
You can also start the wizard from the Guided Configuration link. In the Navigation pane, click Guided Configuration. On the NetVault Configuration Wizard page, click Create backup jobs.
3
In Job Name, specify a name for the job.
Assign a descriptive name that lets you easily identify the job when monitoring its progress or restoring data. The job name can contain alphanumeric and non-alphanumeric characters, but it cannot include non-English characters. On Linux®, the names can have a maximum of 200 characters. On Windows®, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
4
Next to the Selections list, click Create New.
5
Locate the machine acting as the NetVault Backup Server (the machine with the Plug-in Server installed), and double-click it to open it.
6
In the list that appears, locate the Plug-in Server (labeled “VaultDR APM”), and double-click it to open it and display the hard disks on the client system.
7
Select one of the following:
•
To select the entire disk for a backup, click the box to the left of the disk title.
•
To select specific items, double-click a disk to open it. Individual partitions are displayed and made available for selection. NetVault Backup provides data on each type of partition, including the size, status, and type. This information is displayed to the right of each partition, in parentheses. Select the items that you want to back up. Selected items contain a green check, items that are not selected are blank, and omitted items contain a red cross.
•
Primary Partition: Each hard disk can contain up to four different “true partitions.” They are called the primary partitions, and can be individually selected for backup.
•
Extended Partition: This partition is the space on the hard disk not allocated to the primary partitions. This type of partition cannot be selected for a backup. To add it, the entire drive must be selected.
•
Logical Partition: Logical partitions allow multiple system images to run in one machine. This option can be multiple instances of the same OS or different systems. Logical partitions can be individually selected for a backup.
8
Click Save, enter a name in the Create New Set dialog box, and click Save.
The name can contain alphanumeric and non-alphanumeric characters, but it cannot include non-English characters. On Linux®, the names can have a maximum of 200 characters. On Windows®, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
