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,

notes, and references or on the Web:
