As processor speed has increased in recent years and the cost of storage media has decreased, new backup technologies have emerged to keep enterprise data more secure than ever before. One of these is CDP, an abbreviation used in the IT services industry to refer to continuous data protection. In addition, referred to as real time backup or continuous backup, CDP differs from traditional backup technologies in that it allows systems to automatically save a copy of each and every change made to a protected data set.
In practice, CDP allows an enterprise to retain copies of every version of a document and database. This means that all incremental changes can be reviewed and if desired, a chosen version of the document can be restored from the backup media.
Additionally, since all changes are being captured and duplicated, CDP reduces or even eliminates the need for scheduled backups. An enterprise can feel secure in knowing that a complete backup is available at all times, not only directly following an official ‘backup operation’.
Some data protection programs are marketed as CDP when in fact they represent a ‘near continuous’ backup system rather than true CDP. A near continuous backup system is one that allows frequent restore points, but only at set intervals. These intervals may be as frequent as 30 or 60 minutes apart, but if users are unable to restore a document to any incremental point in time, then they lack true continuous data protection.
