In NDB, a Time Machine manages snapshots and log catch-up operations for database protection and recovery. The scenario describes a Time Machine where automatic snapshot and log catch-up activities (both automatic and manual) are halted, and manual snapshots cannot be created. This indicates the Time Machine is in a PAUSED state.
In NDB, the Time Machine states are:
FROZEN: A temporary state during specific operations (e.g., cloning), but it doesn’t halt all activities permanently.
OFFLINE: Indicates the Time Machine is unavailable or not operational, often due to connectivity or configuration issues, but this typically prevents access rather than just halting operations.
PAUSED: Explicitly stops all scheduled and manual snapshot/log activities, often manually triggered by an administrator or due to an error condition (e.g., resource constraints). Operations resume when unpaused.
READY: The normal operational state where snapshots and log catch-ups occur as scheduled.
Given the inability to create manual snapshots alongside halted automatic operations, PAUSED is the most fitting status, as it reflects an intentional or enforced suspension of activities.
