Welcome to the next lesson in our Redis course! So far, you've explored working with Redis Streams, managing key expirations, and using Pub/Sub messaging. Now, it's time to delve into another essential feature: snapshotting in Redis. Snapshotting is a powerful technique to persist data in Redis, ensuring durability and recoverability in case of failures.

In this lesson, you will learn how to perform manual snapshotting in Redis. By the end, you'll know how to:

1. Use the save command to create a synchronous snapshot.
2. Use the bgSave command to trigger an asynchronous snapshot in the background.

Here’s a brief code example to get you started:

This script demonstrates how to use the save and bgSave commands to create snapshots of your Redis data, which can be essential for data durability.

The synchronous save command blocks the Redis server while the snapshot is being created, which can impact performance. In contrast, the asynchronous command creates a snapshot in the background without blocking the server, making it more suitable for production environments.
