Summary
In this chapter, we emphasized the importance of disaster recovery planning, backup and restore strategies, and troubleshooting various system issues. Every system administrator should be able to put their knowledge into practice when disaster strikes. Different types of failures will eventually hit the running servers, so solutions should be found as soon as possible to ensure minimal downtime and to prevent data loss.
This chapter represented the culmination of the Advanced Linux Administration section of this book. In the next chapter, we will introduce you to server administration, with emphasis on KVM virtual machine management, Docker containers, and different types of Linux server configuration.
