continuous data protection LastModified: Friday, April 14, 2006
Abbreviated as CDP and also called continuous backup, continuous data protection refers to backing up computer data by saving as an automated function a copy every time changes are made to that data. It allows users to restore files that are corrupted or that have been accidentally deleted, back to any point in time before they were lost. There are three types of CDP systems: Block-based CDP: logical time-ordered cache of all block-writes across the storage network. Application-based CDP: operates from within the specific application being protected File-based CDP: capture file-system data and metadata events
