Consistent And Relevant Backup - HP Data Protector A.06.11 Recovery Manual

1. Plan
Planning must be prepared by IT administration and should include the following:
• Determine the systems that need to be recovered as well as the time and
level of recovery. Critical systems are all systems required for network to
function properly (DNS servers, domain controllers, gateways, and so on),
Cell Managers and Media Agent clients.
• Determine a recovery method to be used (impacts the required preparations).
• Determine a method to obtain the required information at recovery time, such
as the media that holds the IDB, location of updated SRD file and location
and labels of the Cell Manager backup media.
• Create a step-by-step detailed checklist to guide you through the process.
• Create and execute a test plan to confirm that the recovery will actually work.
2. Prepare for recovery
Depending on the recovery method to be used, the preparation should include:
UNIX :
• Creation of tools, such as the auxiliary disk with the minimum operating
system, network resources, and the Data Protector Disk Agent installed.
• Creation of pre-execution scripts, which collect the storage structure and
other client-specific preparations.
Windows :
• Updating System Recovery Data (SRD) and storing it to a safe place. You
should restrict access to SRD files due to security reasons.
All systems :
• Performing regular and consistent backups.
3. Perform recovery procedures
Follow the procedures and checklists you have tested to recover the affected
system.

Consistent and relevant backup

In the case of a disaster, the target system should be put back into the state it was
at the time of the last valid known backup. Additionally, the system should function
as it had functioned just before the last valid backup performance.
