Establish and Maintain an Isolated Instance of Recovery Data

The media used for backups and the restoration of backups are tested regularly to ensure that they can be relied on in an emergency.

Accurate and complete instructions are maintained for restoring backups. The policy is used to monitor the operation of backups and to prepare for backup failures.

The organization enhances backup security by implementing offline storage solutions, deploying cloud-based isolated backup environments, utilizing off-site facilities, and maintaining a version-controlled backup process. Regular audits ensure backup integrity, while a dedicated network for backup operations minimizes threats and secures data transmission and storage.

With adequate backups, all important data and programs can be restored after a disaster or media failure. To determine your backup strategy, it is important to map / decide on at least the following:

• What systems are on our responsibility to back up?
• How critical is each data asset and how often, based on this, they need to be backed up and to what extent (partial or complete copy)?
• Where are backups stored and how are they protected?
• How long will backups need to be retained?
• What system is used for doing the back up?
• How backup media is destroyed reliably
