Episode 132: Backup and Recovery Methods — GFS, 3-2-1, Testing

This episode focuses on the backup strategies and data recovery techniques that every IT professional must know. We begin with the Grandfather-Father-Son (GFS) backup rotation model, explaining how it balances data redundancy and storage space. Then we dive into the 3-2-1 rule—keeping three copies of your data, on two different media types, with one copy off-site.

We also explore full, incremental, and differential backups, as well as the importance of regularly testing restores to ensure recovery plans actually work when needed. These strategies often appear in scenario-based exam questions, where you’ll need to select the best approach for business continuity or disaster recovery. Brought to you by BareMetalCyber.com.
