System Back up and Data Loss

If you've ever lost some data - something you have spent ages creating - you'll know how impirtant it is to back up, especially given that data loss can happen in so many different ways and almost seems inevitable.

Data Loss

Data loss is an error condition in information systems in which information is destroyed by failures (like failed spindle motors or head crashes on hard drives) or neglect (like mishandling, careless handling or storage under unsuitable conditions) in storage, transmission, or processing. Information systems implement backup and disaster recovery equipment and processes to prevent data loss or restore lost data. Data loss can also occur if the physical medium containing the data is lost or stolen.
