Overview - 1-Touch for Windows and UNIX
The NetApp 1-Touch recovery solution, often referred to as Bare Metal Recovery is used to quickly recover a failed computer. By automatically rebuilding the operating system, you can recover systems with defective components such as inaccessible volumes or failed disks without the need to manually reinstall the individual software packages or operating systems.
This feature is available on the Windows platform and on various UNIX platforms. A 1-Touch server is required to use this feature, except for Linux computers. The 1-Touch server secures the required information from the client's backup and then uses this information to re-create the client environment. Based on the client environment, you can use the CommCell Console or the 1-Touch wizard to run the actual recovery process.
Linux clients do not require 1-Touch server. The required information for 1-Touch recovery is available on the CommServe and the Linux Live CD.
Determine Whether Your Environment Supports 1-Touch Server
Use the following table to determine whether your environment supports 1-Touch Server:
|Is 1-Touch Server required?||Yes. For instructions, see Deployment - 1-Touch Server.||Yes. For instructions, see Deployment - 1-Touch for AIX.||NA||Yes. For instructions, see Deployment - 1-Touch for HP-UX.||1-Touch Server is not required.||Yes. For instructions, see Deployment - 1-Touch for Solaris.|
|Can you install the 1-Touch Server on a virtual machine?||Yes||Yes||NA||Yes||NA||Yes|
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.
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.
WindowsYou 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.
Cross hardware restores are supported with the following limitations:
The 1-Touch documentation uses the following terminology:
|A computer that has the File System iDataAgent installed on it.|
|A server that is used for 1-Touch recovery of clients.|
|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.|
|This is a file that contains all the information required to initiate the 1-Touch recovery. Use this file to create the Live CD.|
|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.|
|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.|
