Backup Technology
Systems for creating and retaining protected copies of organisational information.
Backup & Disaster Recovery
Backup is not simply about keeping another copy of a file. Organisations need to consider what must be protected, how frequently it changes, where copies are stored and what happens when recovery is required.

What protection involves
Systems for creating and retaining protected copies of organisational information.
Storage infrastructure supporting backup capacity and retention requirements.
Technology and planning around restoring important information and systems after disruption.
A wider view of the technology an organisation depends on and the steps required when normal operations are interrupted.
Backup matters most before it is needed.
A useful starting point is a short list: which systems and information matter most, how often they change and how quickly they would need to be restored.
