+The `SAVE` commands performs a **synchronous** save of the dataset producing a
+_point in time_ snapshot of all the data inside the Redis instance, in the form
+of an RDB file.
+
+You almost never want to call `SAVE` in production environments where it will
+block all the other clients. Instead usually `BGSAVE` is used. However in case
+of issues preventing Redis to create the background saving child (for instance
+errors in the fork(2) system call), the `SAVE` command can be a good last resort
+to perform the dump of the latest dataset.
+
+Please refer to the [persistence documentation][tp] for detailed information.
