But deploying disk-based systems likewise means that it is no longer necessary to wait impatiently to get hold of tape catalogues that are both held in distant locations and likely to contain data from only as far back as the night before disaster struck anyway.
This situation, combined with the hours of time required to copy information from tape to repaired or replaced servers, means that a restore typically takes between two and five days - timescales which are no longer acceptable in today’s information-dependent world.
Because disk-based backups can be undertaken as frequently as desired, on the other hand, the recovery point objective can be pre-set to hours or even minutes before trouble hit.
In addition, restoration of data takes mere minutes as it is simply sent from a remote vault over a broadband connection and so recovery time objectives are shortened significantly.
What this all means, in practice, therefore, is that the first major change to occur in backup technology in the last 50 years is now a risk-free and affordable option.
As a result, progressive organisations all over the world are already starting to take advantage. And the time is now right to join them.
