Cluster Rollback Strategy with Retention Policies
What is a Cluster Rollback Strategy?
A cluster rollback strategy is a critical component of any virtualized environment, providing a safety net in the event of a failure or disaster. By implementing a cluster rollback strategy with retention policies, users can ensure that their virtual machines are properly backed up and can be quickly restored in the event of an issue.
How to Implement a Cluster Rollback Strategy
To implement a cluster rollback strategy with retention policies, users can follow these steps:
- Configure the cluster rollback strategy in vSphere Hypervisor.
- Set up retention policies to determine how long backups are retained.
- Test the cluster rollback strategy to ensure it is working properly.
