Backup Strategy Guidelines

3-2-1 Backup Rule

Maintain 3 copies of your data: original plus 2 backups. Store backups on 2 different media types. Keep 1 copy offsite. This ensures protection against hardware failure, site disasters, and cyber threats.

Backup Testing

Regularly test backup restoration to ensure data recoverability. Schedule quarterly test restores, verify backup integrity, document restoration procedures, and train staff on recovery processes.

Retention Best Practices

Implement tiered retention: keep daily backups for 30 days, weekly for 3 months, monthly for 1 year, and annual backups for 7+ years. Consider regulatory requirements for different data types.
