Three copies
Keep the original data plus at least two separate backup copies. This gives you more than one recovery route if something goes wrong.
Backup review
The 3-2-1 backup strategy.
A simple rule for making sure one hardware failure, mistake or security incident does not take all your important data with it.
Two different media
Use different storage types or systems, such as local disk, a dedicated backup device and cloud storage. One failure should not affect every copy.
One off-site copy
Keep at least one copy away from the main site. Off-site protection helps when theft, fire, flooding or ransomware affects your building and connected systems.
A useful checklist
A backup is only useful if it can be restored.
Identify critical files, applications and systems before choosing backup coverage.
Use encryption, strong access controls and multi-factor authentication where available.
Keep backup credentials separate from everyday user accounts.
Test restoring files regularly and document who is responsible for recovery.
Review retention periods so you can recover from mistakes discovered weeks or months later.
