Before you can begin the process of performing a bare metal restore for a Linux machine, you must ensure that the following conditions and criteria exist:
- Backups of the machine you want to restore. You must have a functioning Rapid Recovery Core containing recovery points of the protected server you want to restore.
- Hardware to restore (new or old, similar or dissimilar). The target machine must meet the installation requirements for an agent; for details, see the Rapid Recovery Installation and Upgrade Guide.
- Live DVD boot image. Obtain the Linux Live DVD ISO image, which includes a bootable version of Linux. Download it from the Dell Data Protection | Rapid Recovery License Portal at https://licenseportal.com. If you have any issues downloading the Live DVD, contact Dell Rapid Recovery support.
- Image media and software. If using physical media, you must have a blank CD or DVD and disk burning software, or software to create an ISO image.
- Compatible storage drivers and network adapter drivers. If restoring to dissimilar hardware, then you must have compatible storage drivers and network adapter drivers for the target machine, including RAID, AHCI, and chipset drivers for the target operating system, as appropriate.
- Storage space and partitions, as appropriate. Ensure that there is enough space on the hard drive to create destination partitions on the target machine to contain the source volumes. Any destination partition should be at least as large as the original source partition.
- Restore path. Identify the path for the restore, which is the path for the device file descriptor. To identify the path for the device file descriptor, use the fdisk command from a terminal window.
A bare metal restore for Linux requires a Live DVD boot image, which you download from the Dell Data Protection | Rapid Recovery License Portal. You will use this image to start the destination Linux machine. Based on the specifics of your environment you may need to transfer this image to physical media such as a CD or DVD. You must then virtually or physically load the boot image, and start the Linux server from the boot image.
The Live DVD was previously known as the Live CD.
Managing a Linux boot image is a step in Performing a bare metal restore for Linux machines.
You can perform the following tasks:
The first step when performing a bare metal restore (BMR) for a Linux machine is to download the Linux Live DVD ISO image from the Dell Data Protection | Rapid Recovery License Portal. The Live DVD functions with all Linux file systems supported by Rapid Recovery, and includes a bootable version of Linux, a screen utility, and the Rapid Recovery Universal Recovery Console (URC) interface. The Rapid Recovery Universal Recovery Console is an environment that is used to restore the system drive or the entire server directly from the Rapid Recovery Core.
The International Organization for Standardization (ISO) is an international body of representatives from various national organizations that sets file system standards. The ISO 9660 is a file system standard that is used for optical disk media for the exchange of data and supports various operating systems. An ISO image is the archive file or disk image, which contains data for every sector of the disk as well as the disk file system.
You must download the Live DVD ISO image that matches your version of Rapid Recovery. The current version of Live DVD is available from the Dell Data Protection | Rapid Recovery License Portal at https://licenseportal.com. If you need a different version, contact Dell Rapid Recovery support

This task is a step in Performing a bare metal restore for Linux machines. It is part of the process for Managing a Linux boot image.
Complete the steps in this procedure to download the Live DVD ISO image.
- Log into the Dell Data Protection | Rapid Recovery License Portal athttps://licenseportal.com.
- Access the Downloads area.
- Scroll down to Linux Based Applications and, from the Linux Live DVD section, click Download.
- Save the Live DVD ISO image. If you are restoring a virtual machine, you can save it to a network location, and set the VM to start up from a CD or DVD drive associated with the ISO image.
- If restoring from a physical machine, burn the Boot CD ISO image onto a compact disc (CD) or digital video disk (DVD) from which the target machine can be started. For more information, see Saving the Live DVD ISO image to media.
