Release 10.1A: OpenEdge Data Management:
Database Administration

Developing a recovery plan

A recovery plan documents how you will recover your system if it fails. When developing a recovery plan, you must consider every potential failure, from short-term power outages and disk failures to environmental disasters such as earthquakes.

To develop a database recovery plan, you first need to determine the availability requirements for the database application. Consider the following questions:

How many transactions can you afford to lose?
How long can the application be offline while you perform scheduled maintenance, such as backups?
If the system or database becomes unavailable, how much time can you spend recovering?
If you use transactions that affect more than one database, can you allow transactions to occur inconsistently in those databases?
How will you test your recovery plan?

Use the tables in the following sections to develop a recovery plan. These tables provide a range of answers to these questions and backup and recovery suggestions for each.
