Disaster recovery methods
Data Protector supports the following disaster recovery methods:
•Manual disaster recovery
This is a basic and very flexible disaster recovery method. You need to install and configure the DR OS. Then use Data Protector to restore data (including the operating system files), replacing the operating system files with the restored operating system files.
•Automated disaster recovery
Automated System Recovery (ASR) is an automated system on Windows systems, which reconfigures a disk to its original state (or resizes the partitions if the new disk is larger than the original disk) in the case of a disaster. ASR thus enables the Data Protector drstart.exe command to install the active DR OS that provides Data Protector disk, network, tape and file system access.
•Disk delivery Disaster recovery
On Windows clients, the disk of the crashed system (or the replacement disk for the physically damaged disk) is temporarily connected to a hosting system. After being restored, it can be connected to the faulty system and booted. On UNIX systems, the auxiliary disk with a minimal operating system, networking, and Data Protector agent installed is used to perform Disk Delivery Disaster Recovery.
•Enhanced Automated Disaster Recovery (EADR)
Enhanced Automated Disaster Recovery (EADR) is a fully automated Data Protector recovery method for Windows clients and Cell Manager, where user intervention is reduced to minimum. The system is booted from the disaster recovery CD ISO image and Data Protector automatically installs and configures DR OS, formats and partitions the disks, and finally recovers the original system with Data Protector as it was at the time of backup.
•One Button Disaster Recovery (OBDR) is a fully automated Data Protector recovery method for Windows clients and Cell Manager, where user intervention is reduced to a minimum. The system is booted from the OBDR tape and automatically recovered.
For a list of supported disaster recovery methods for a particular operating system, see the Support Matrices in the HP Data Protector product announcements, software notes, and references or on the Web:
