Regular Backups

When you have identified the key critical data that your company possesses, it is important to maintain this data in a way that ensures:-

• confidentiality: protecting information from unauthorised access and disclosure
• integrity: safeguarding the accuracy and completeness of information and processing methods;
• availability: ensuring that information and associated services are available to authorised users when required.

Backing up data is a key part of this and must achieve the following:-

• Regular Backups - typically one for every week day plus a separate backup copy for each Friday of the month, in this way you can recover any file up to one month old.

• A recent backup must always be held offsite - In this way if a fire or explosion occurred the data can be restored onto a new system.

• Secure Backups - Backup's must be kept safely, so that data cannot be extracted from them by an unauthorised third party, this can be helped by using encryption.
