Business continuity planning starts with an analysis and identification of critical and non-critical factors for incident recovery. As mentioned above, this analysis should be done at an enterprise level first, as this will define the priority of planning for Exasol business continuity in the context of your organization's complete ecosystem.
The priority of Exasol in your overall continuity plan will be defined by how you use the data. Specifically, the more operational importance the data kept in Exasol has, the faster you will need to have the database up and running in the event of an incident. For example, if you use Exasol data to make immediate operational decisions multiple times per day, the higher the priority Exasol will have in your business continuity plan. Conversely, if the data is only accessed periodically, such as once a week, to provide non-critical reports, Exasol will have a lower priority in your continuity plan
This analysis is important, because the cost and complexity of your business continuity plan for Exasol directly depends on how fast you need to recover it in the event of an outage.
First you should understand the general Terminology and Time Line involved with business continuity plans.
Then you need to establish the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for your plan for Exasol based on your requirements, because these two factors impact cost and complexity of setting up business continuity for Exasol, and will also impact other planning considerations, notably storage space required and your backup strategy.
Finally, you can consider potential Synchronous Dual Data Center (SDDC) in Detail.
