There are different kinds of disasters you may need to recover from. At R1Soft, we consider any situation requiring you to take your server off-line to Restore as Disaster Recovery, and we call this Bare-Metal Restore. You typically want to perform a Bare-Metal Restore any time you need to Restore more than just a handful of files.
There are two options for performing a Bare-Metal Restore.
Disaster Recovery Boot Media supports the following two (2) Recovery Methods for both Windows and Linux Bare-Metal Restores.
- Live CD (Disaster Recovery Boot Media Version 3.18.1 and higher) - Download the CD-ROM ISO image, also referred to as Live CD. This ISO image should be burned to a CD-ROM using a CD-writer drive and any common CD burning software (see Write ISO file CDs). This method requires physical access to the computer to insert the CD-ROM. It cannot be easily automated or remotely initiated. See Use a boot CD-ROM.
- PXE Network Boot (Disaster Recovery Boot Media Version 3.18.1 and higher) - With PXE Boot and an installed Server Backup it is possible to provide a hands-free, fully automated Disaster Recovery and re-deployment system for the entire data center. See Use PXE network boot.
To use this method, you need a special "boot" server running the services required for PXE Environment to work - DHCP and TFTP, as well as NFS service. Having this "boot" server and Server Backup, you will be able to carry out a hands-free, fully automated Disaster Recovery and re-deployment system. For servers which provide remote access to the server console, it can be done via IP-KVM solutions. This method does not require physical access to the server.
Each of the listed options has two sub-options:
- Booting into Agent environment - To use this option, you need a running Backup Manager installed on a machine different from one to which you are going to restore.
- Booting into Server environment - This option allows to restore the current machine from a Disk Safe located on a network drive or on the secondary physical disk. When you boot from Live CD Server or PXE Network Boot Server, then a full-fledged Backup Manager runs. In the Backup Manager Web Interface you will be able to add the Disk Safe to restore from.
Choose the option that fits your specific needs.
