You can use Commvault's 1-Touch Bare Metal Recovery to recover a failed computer or to create a clone of a server. With 1-Touch, you can easily recover a computer by automatically rebuilding the operating system and all the applications on a new server that has either similar or different hardware.
Depending on the client environment, you can use the CommCell Console or the 1-Touch wizard to run the recovery process. The 1-Touch recovery process secures the required information from the client's backup and then uses this information to re-create the client environment.
Windows clients do not require a 1-Touch server. The required information for 1-Touch recovery is available on the CommServe and the Windows Live CD.
Key Features
Bare Metal Recovery Using 1-Touch for Windows offers the following key features:
Fully unattended operating system reinstall: You can initiate the recovery process of a single or multiple clients from a central location, such as the CommServe computer.
Point-In-Time Restore: Using the 1-Touch recovery solution, you can restore the system state of a client using the specific date and time when the system state backup was performed.
Support for Block-Level Backups: You can perform a recovery operation from block-level backups. Restores from block-level backups are faster. In addition, data integrity is ensured because block-level backups engage Volume Shadow Copy Service (VSS) writers and generate a crash-consistent snapshot of the system volume.
Cross Hardware Restore: You can perform the 1-Touch Recovery to a target Windows client with completely different hardware configurations. The target system can have different network interface adapters, mass storage devices, video adapters, motherboards, and CPUs.
