The Importance of Backups and the Limitations of RAID

In this chapter, the speakers discuss the importance of backups and highlight that RAID is not a backup solution. They explain that RAID is about maintaining the system's data and preventing data loss, but it does not protect against accidental deletion, ransomware attacks, or power outages. They emphasize the need for backups, especially in situations where there is limited storage capacity. The speakers also mention a story about someone's cat damaging their storage server and stress the necessity of having a backup. They mention an alternative option of using an rsync.net account to backup to the cloud, but note that hosting one's own backup is often more cost-effective.
