WorksheetsA+ - 19B - Implement Backup and Recovery
Total questions: 2
Worksheet time: 13mins
The text discusses backup operations, emphasizing the importance of data backup for storing copies of critical data to protect against data loss due to disasters like file corruption or hardware failure. It explains the need for structured backup schemes in large organizations, covering backup schedules, file specifications, storage locations, and recovery methods.
Different backup methods and strategies are explored, including personal backups for home users or small workgroups, which often involve external hard drives or cloud-based storage. Windows-specific backup options such as File History and Backup and Restore Center are detailed, along with their configuration and restoration processes.
Backup methods are categorized into full backups, incremental backups, and differential backups, each with its own data selection, time and storage requirements, recovery complexity, and archive attribute considerations. Synthetic backups, which assemble full backups from incremental backups, are also discussed as an option for reducing data transfer requirements.
Backup media requirements, including rotation schemes like the grandfather-father-son (GFS) scheme, are explained to manage backup retention periods effectively. The text also compares on-site and off-site storage options, highlighting the importance of off-site backups for disaster recovery.
Additionally, online and offline backup media distinctions are outlined, with recommendations for keeping some backup media offline for enhanced security, especially against threats like crypto-ransomware. The 3-2-1 backup rule is introduced as a best-practice guideline to ensure comprehensive backup strategies.
Finally, backup testing and recovery best practices are discussed, emphasizing the importance of regularly testing backup procedures to ensure reliability and mitigate risks from media failure or configuration oversights.
