Redis Yum Save: How to Enable Automatic Backups in Redis on CentOS

Introduction

Redis is a popular in-memory data store that is commonly used for caching, session management, and real-time analytics. One important aspect of managing a Redis server is ensuring that your data is backed up regularly to prevent data loss in case of unexpected failures. In this article, we will explore how to enable automatic backups in Redis on CentOS using the yum package manager.

Step 1: Install Redis on CentOS using yum

Before we can enable automatic backups in Redis, we first need to install Redis on our CentOS server using the yum package manager. To do this, run the following command:

sudo yum install redis

This command will download and install the Redis server and client on your CentOS system.

Step 2: Configure Redis for automatic backups

Once Redis is installed, we need to configure it to perform automatic backups. Redis provides a built-in feature called SAVE that allows you to trigger a manual backup of the dataset to disk. However, for scheduled backups, we can use the redis yum save script provided by the Redis package.

To enable automatic backups, create a new cron job by running the following command:

sudo echo "0 3 * * * root /usr/libexec/redis/yum save" > /etc/cron.d/redis-yum-save

This cron job will run the redis yum save script every day at 3:00 AM and save the Redis dataset to disk.

Step 3: Verify automatic backups

To verify that automatic backups are working correctly, you can check the backup files created by the redis yum save script in the default Redis data directory (/var/lib/redis). You should see new backup files generated daily with a timestamp in the filename.

Conclusion

Enabling automatic backups in Redis on CentOS is a crucial step in ensuring the safety and integrity of your data. By following the steps outlined in this article, you can set up scheduled backups for your Redis server and protect your data from unexpected failures.

Now you can rest assured that your Redis data is safely backed up and secure!
