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
