Study Notes
- Backing up data is crucial for retrieving previous versions and recovering from disasters.
- Considerations when planning a backup system include the amount and type of data, storage location and media, backup software, and backup frequency.
- Full backup involves copying all files on a system, which takes a long time but is quick to restore.
- Differential backup only copies data modified since the last full backup, resulting in moderate backup and restore times.
- Incremental backup backs up new files and modified data since the last incremental backup, having low backup time but high restore time.
- Synthetic backup combines all data sets to create a full backup quickly and efficiently.
- Regularly simulate restoring data to audit the backup process and confirm data integrity.
- On-site backups are immediate and less expensive, while offsite backups offer flexibility in restoration.
- The Grandfather, Father, Son (GFS) rule is a backup rotation strategy consisting of monthly, weekly, and daily backups.
