Bare-Metal is used to describe a highly efficient Disaster Recovery Method for a Host. A Bare-Metal Restore does not require any operating system installation or backup software installation. You can stream your Disk Images across the network directly onto new or replacement hardware. There is no need to format or partition any hard disks, hence the term restoring to "Bare-Metal."
There are three (3) options for performing a Bare-Metal Restore for Linux and Windows platforms.
- Live CD
- Live Boot™ Remote Restore
- PXE Network Boot
After you boot your Host using one of the above three (3) methods, you will need to follow the process of Bare-Metal Restore in your CDP Server.

When Restoring from a Disk Safe using encryption, you will be prompted for the passphrase. Bare-Metal Restores of Disk Safes using encryption are not possible without first entering the passphrase.
At the beginning of the Restore operation, the RSA Public Key and Backup Key are sent to the Agent over an encrypted socket. The Agent uses Keys to decrypt the Disk Image on its end as it is received over the network. Your data is always encrypted until the last minute when it is decrypted before being written to the hard drive on the Host you are Restoring to.
