Continuous data protection (CDP)
Continuous data protection (CDP), also called continuous backup, is a storage system in which all the data in an enterprise is backed up whenever any change is made. In effect, CDP creates an electronic journal of complete storage snapshots, one storage snapshot for every instant in time that data modification occurs.A major advantage of CDP is the fact that it preserves a record of every transaction that takes place in the enterprise. In addition, if the system becomes infected with a virus or Trojan, or if a file becomes mutilated or corrupted and the problem is not discovered until some time later, it is always possible to recover the most recent clean copy of the affected file.
A CDP system with disk storage offers data recovery in a matter of seconds -- much less time than is the case with tape backups or archives. Installation of CDP hardware and programming is straightforward and simple and does not put existing data at risk.
IBM® Tivoli® Continuous Data Protection for Files is continuous backup software that protects your most important files.
This real-time, continuous data protection solution for file servers and user endpoints automatically backs up your most critical files the moment they are saved.
To help you capture every save of a file when it occurs and protect against corruption, file loss or system loss, you can specify as many as three target backup/replication ares for high-priority files.
To minimize the backup/recovery window, this continuous data backup software uses rapid disk-to-disk protection and restore capabilities.
To optimize recovery point objectives (RPO) and recovery time objectives (RTO).
It retains data files for predefined lengths of time, and version the separate copies of the files to facilitate date-based restore.
Easy to implement and manage, it runs transparently in the background with a light footprint.
Working with multiple backup/replication targets (local disk, web, file server, NAS device, Tivoli Storage Manager), you can specify a remote file server or Tivoli Storage Manager for off-machine protection when a user is connected, so real-time backup still occurs.
