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,
