Explanation

To configure a database with a Time Machine protection mode that includes the Log Catchup operation in NDB, the most essential component is a Service Level Agreement (SLA) that supports continuous log retention. The Log Catchup operation enables point-in-time recovery (PITR) by replaying transaction logs from a specified point, ensuring minimal data loss and meeting Recovery Point Objective (RPO) requirements. This functionality depends on the Time Machine being configured with an SLA that includes the "Continuous Log Retention" option, which ensures transaction logs are captured and retained continuously alongside snapshots.
