The problem
A single backup copy on the same server does not protect well against disk failure, ransomware or accidental deletion.
Recommended approach
Use a practical 3-2-1 approach: multiple copies, different storage media, and at least one copy separated from the primary environment.
Step-by-step checklist
- Identify critical data and recovery targets.
- Keep more than one backup copy.
- Use separate storage for backup data.
- Keep an offline or offsite copy where appropriate.
- Test restores regularly, not just backup jobs.
