Summary

Duration in seconds of the most recent background RDB save operation. Long save times indicate large dataset size, slow disk I/O, or high memory fragmentation forcing more work during copy-on-write. Typical values range from <1s for small datasets to 60s+ for multi-GB datasets. Increasing trends over time signal dataset growth and may require save interval tuning to reduce impact.
