Documenting and delegating ownership of own backup processes
1. Task description

In connection with the data systems listing, we describe for which systems we are responsible for the implementation of the backup. The organization’s own backup processes are documented and an owner is assigned to each. The documentation includes e.g.:

  • which system is used for backing up data?
  • how are the backups protected (encryption, physical location)?
  • how long are the backups retained?

Regular testing, evaluation, and recovery instructions for backups
1. Task description

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.

Determining responsibilities for backing up important information assets
1. Task description

With adequate backups, all important data and programs can be restored after a disaster or media failure. An important first step in a functional backup strategy is to identify who is responsible for backing up each piece of data. Determining the responsibility for backup is the responsibility of the owners of the information assets (systems, hardware).

If the backup is the responsibility of the partner, we will find out:

  • how comprehensively does the partner back up the data?
  • how the data can be recovered if necessary?
  • how the backups are agreed in the contracts?

If the backup is our own responsibility, we will find out:

  • whether the data backup process exists and is documented?
  • whether the coverage and implementation cycle of the backup is at the level required by the importance of the data?

Protecting backups against intentional and unintentional deletion and manipulation
1. Task description

Copies of backups must be kept separate from the organization's production environment. Access to these copies should be restricted to only employees and system processes involved in data restoration.

Backups, which are inaccessible through the organization's networks, should be created regularly.

These security measures ensures the integrity and availability of the backups.

Defining a backup strategy
1. Task description

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
