If you experience any kind of data loss, you need to have a back-up system in place so that you can restore the original data. Backing up your data means making a copy of your data. This data can then be restored in the event of a disaster, or complete computer crash, or if any files have been accidentally deleted or have been corrupted.

Which Back-up System?

Backups generally contain a least one copy of our data, and depending on how much data you have will depend on the storage facilities you require, and how complicated the management of this facility will be. Before it is sent to storage, data is selected, extracted and then manipulated.

Many techniques have been developed to streamline this procedure which include data sources, or where the data comes from as well as encryption, duplication and compression, that is, compacting large files.

A host of systems are available today which range from copying our data onto a CD and filing it in our desk draw at home, right up to fully managed services which are maintained by companies who specialise in this. Some of the services offered by these companies are:-

• Comprehensive backup: a complete copy of all your business information is stored in case of disasters and usually includes a Comprehensive Archiving system. This groups data and allows access to only certain bits which are relevant at that time, i.e. year end tax reports.
• Fully managed: Data is conducted by a specialised company who supply daily reports of backups as well as notification of any failures.
• Web based Systems: This allows access to your data via a web connection from anywhere in the world.
