On replicas, RDB supports partial resynchronizations after restarts and failovers.RDB allows faster restarts with big datasets compared to AOF.The parent process will never perform disk I/O or alike. RDB maximizes Redis performances since the only work the Redis parent process needs to do in order to persist is forking a child that will do all the rest.RDB is very good for disaster recovery, being a single compact file that can be transferred to far data centers, or onto Amazon S3 (possibly encrypted).This allows you to easily restore different versions of the data set in case of disasters.

For instance you may want to archive your RDB files every hour for the latest 24 hours, and to save an RDB snapshot every day for 30 days.

RDB is a very compact single-file point-in-time representation of your Redis data.

The most important thing to understand is the different trade-offs between the Notice that, in this case, when Redis restarts the AOF file will be used to reconstruct the original dataset since it is guaranteed to be the most complete.

RDB + AOF: It is possible to combine both AOF and RDB in the same instance.

No persistence: If you wish, you can disable persistence completely, if you want your data to just exist as long as the server is running.

Redis is able to rewrite the log in the background when it gets too big. Commands are logged using the same format as the Redis protocol itself, in an append-only fashion.

AOF (Append Only File): The AOF persistence logs every write operation received by the server, that will be played again at server startup, reconstructing the original dataset.

RDB (Redis Database): The RDB persistence performs point-in-time snapshots of your dataset at specified intervals.

Redis itself provides a range of persistence options: Persistence refers to the writing of data to durable storage, such as a solid-state disk (SSD). How Redis writes data to disk (append-only files, snapshots, etc.)
