Fully unattended operating system reinstall |
1-Touch recovery helps to recover a crashed system in the least amount of time. By automatically rebuilding the operating system, you can recover systems with defective components such as inaccessible volumes or crashed disks. You don't need to reinstall the individual software packages or operating systems manually.
This feature is available on the Windows platform as well as on various Unix platforms. You need to setup a 1-Touch server to enable this feature. Depending on client environment, you can use the CommCell Console or the 1-Touch wizard to run the recovery process. The 1-Touch server secures the required information from the 1-Touch client's backup and then uses this information to recreate the client's environment.
Linux clients do not require 1-Touch server. The required information for 1-Touch recovery is available on the CommServe and Linux Live CD.
The 1-Touch Recovery involves the following key features:
You can initiate the recovery process of a single or multiple clients from a central location, such as the CommServe. This will be useful when you want to reinstall the operating system on all the clients connected to a CommServe.
You can restore the system state of a client, backed up on a specific date and time.
On Windows platform, 1-Touch recovery can be performed in online and offline modes. Online recovery involves many steps to be carried out manually and is a very slow process for a Disaster Recovery. This process uses Windows distribution to install the operating system and then initiate a recovery which makes it slower. Also, a lot of space is needed on the 1-Touch server to maintain the distributions and the Calypso software to be installed after the operating system installation is complete.
Offline recovery does away with operating system installation and the restore is performed while running on Boot CD itself making this a quick process for a Disaster Recovery.
You can perform the 1-Touch Recovery to a target Windows system with completely different hardware configurations. The target system can have different network interface adapters, mass storage devices, video adapters, motherboards, and CPUs
The 1-Touch documentation uses the following terminology:
1-Touch Client |
A computer that is connected to 1-Touch server |
1-Touch Server |
A server that is used for 1-Touch recovery of 1-Touch clients. |
Live CD |
A CD used to boot the client for 1-Touch recovery. |
Dissimilar Disk Restore |
This term is used in the 1-Touch recovery of Windows clients. When the disk configuration of the restored system is different than that of the backed up system, you need to perform a Dissimilar Disk Restore. |
Asymmetric Disk Restore |
This term is used in 1-Touch recovery of Unix clients. When the disk configuration of the restored system is different than that of the backed up system, you need to perform the Asymmetric Disk Restore. |
ISO Image |
This is a file that contains all the information required to initiate the 1-Touch recovery. Use this file to create the Live CD. |
Offline Restore |
This term is used in the 1-Touch recovery of Windows clients. A recovery procedure in which the operating system is restored and not re-installed. An access to 1-Touch server is not required to perform the Offline Restore. |
Online Restore |
This term is used in the 1-Touch recovery of Windows clients. A recovery procedure in which the operating system is re-installed. You need access to 1-Touch server to perform the Offline Restore. |
Answer File |
The client answer file contains information such as the computer name, operating system, IP address, and disk partition/format information. This information is used during the 1-Touch Recovery for silent deployment of operating system and restoration of the client. |
