Keep Redis data safe even when the server restarts or something goes wrong.
Redis is primarily an in-memory database, but it can persist data to disk so information is not completely lost when a server restarts. Redis provides mechanisms such as snapshots and append-only logging to save changes.
Each persistence strategy makes different trade-offs between performance, recovery speed, and how much recent data could be lost after a failure. Choosing the right approach depends on whether Redis is being used as a cache, a primary data store, or something in between.
