Scenario: To plan a disaster recovery solution using IBM Security Guardium Key Lifecycle Manager
As an administrator, you can use replication in IBM Security Guardium Key Lifecycle Manager to protect mission-critical data and ensure business continuity.
Master server is the primary system that is being backed up and replicated to one or more secondary servers, called clone servers. You must configure IBM Security Guardium Key Lifecycle Manager on the master and clone servers to schedule replication. New keys are created only on the master server. Clone servers can serve keys.
For more information, see Configuring replication.Solution
To achieve a disaster recovery solution, you can configure your IBM Security Guardium Key Lifecycle Manager servers to use replication with one master server and at least one clone server in geographically different zones. Ensure that incremental replication is enabled so that the clone server always contains almost up-to-date IBM Security Guardium Key Lifecycle Manager data.
You can configure maximum 20 clone servers.
Prerequisites
Ensure that IBM Security Guardium Key Lifecycle Manager is installed on the master and clone servers.
Steps
Configure replication on the master and clone servers. Incremental replication is enabled by default. For more information, see Enabling and configuring full replication.
Other data recovery options
- Backup and restore
- Creating a data backup and restoring it on another server is a basic and simple method for
protecting data. This method is manual and inexpensive. It relies on snapshots, which are copies of
the data that are taken at a predetermined point in time. Hence, in case of a disaster, you can only
recover the snapshot that was last restored.
For more information, see Configuring backup and restore.
- Multi-Master cluster
- A Multi-master cluster solution provides high availability of data and supports recovery of data
in case of a disaster. This method is automated and continuously replicates data in real time.
However, it involves specific installation requirements, additional configuration, and requires a
specialized Db2 administrator.
