+  # Redis Persistence Options:
+  #
+  # 1.Redis Database File (RDB) persistence takes snapshots of the database at intervals corresponding to the save directives in the redis.conf file. The redis.conf file contains three default intervals. RDB persistence generates a compact file for data recovery. However, any writes since the last snapshot is lost.
+
+  # 2. Append Only File (AOF) persistence appends every write operation to a log. Redis replays these transactions at startup to restore the database state. You can configure AOF persistence in the redis.conf file with the appendonly and appendfsync directives. This method is more durable and results in less data loss. Redis frequently rewrites the file so it is more concise, but AOF persistence results in larger files, and it is typically slower than the RDB approach
