Continuous Data Protection

Continuous Data Protection ( CDP), often called continuous backup or real-time backup, is a process for the continuous, incremental backup. CDP is used to add databases to the effects of corrupted data, which were first noticed some time after their adverse manipulation to protect. Recovery at any non predefined time is made possible.

Characteristics

Continuous Data Protection differs from traditional backup idea in that, for the restoration No specific date ( the date on which the last backup was created) must be specified. User- initiated backups are obsolete because the backup system will recognize in the background when data has been changed, and takes into account these changes in status in the context of continuous assurance. Usually when saving data to an internal disk are written asynchronously to a remote disk. Is the means of network connection described, remote disk outside the organization, one often speaks of Online Backup.

Benefits

Benefits of Continuous Data Protection are the significant reduction in the need to restore the data and the resumption of normal operation period, and the lower risk of data loss.

Risks and disadvantages

Although Continuous Data Protection is likely to increase data security in organizations, including the associated challenges and risks should be considered: CDP provides additional traffic and requires a certain minimum bandwidth, in order not to weaken the network performance, especially when the data to be saved in large files are present. Internal and external networks must be checked for suitability for their safety.
