Data sync appears delayed

Sync lag is often related to queue pressure, storage latency, or unstable mount state.

Diagnosis

• Check whether large indexing batches are still running.
• Verify external drive health and connection stability.
• Confirm available disk space for index updates.

Mitigation

• Pause non-critical indexing jobs during active edit windows.
• Process large libraries in staged batches.
• Restart sync services only after verifying mount consistency.
