什么是CDP（连续数据保护）？

CDP：连续数据保护 (CDP: Continuous Data Protection)

CDP is an abbreviation of "Continuous Data Protection". It is also called as a real-time backup, is a system of data storage that backs up data in an organization or enterprise on a system of the computer, whenever an automatic capturing and modification of data happened. It keeps up an incessant journal of data modifications and makes that journal feasible to re-establish and update a system of data storage to any preceding spot in the duration of time.

CDP是“连续数据保护”的缩写 。它也称为实时备份，它是一种数据存储系统，每当发生自动捕获和修改数据时，便在计算机系统上备份组织或企业中的数据。它可以保持不断的数据修改日志，并使该日志可在一段时间内重新建立并更新到任何先前位置的数据存储系统。

CDP的优势 (Advantages of CDP)

The software of Continuous Data Protection provides a constant preceding spot in the duration of time to use for re-establishment and updating of a system of data storage.
连续数据保护软件在持续时间内提供恒定的先验位置，用于重建和更新数据存储系统。
To continuously replicate and restore the data to storage in the system, CDP makes the use of change-block tracking, which helps in carrying out incremental backups.
为了连续地将数据复制并还原到系统中的存储中，CDP使用了变更块跟踪，这有助于执行增量备份。

In the process of using Continuous Data Protection backup in the system, as not any snapshots are formed, the additional space in the storage of system foundation has not required. The process of modification and restoring of data in the storage utilizes just about 8-10% of the intended data storage, which saves a considerable sum of space.
在系统中使用Continuous Data Protection备份的过程中，由于未形成任何快照，因此不需要在系统基础的存储中增加空间。存储中数据的修改和还原过程仅使用了预期数据存储的8-10％，从而节省了大量空间。
All modifications done by users of applications and data are maintained by the journal of data modification in the incessant record.
应用程序和数据的用户所做的所有修改都由连续记录中的数据修改日志维护。
In the process, by keeping away from the effect of performance of a distinctive usual snapshot, incessant backup users of captured data make use of the journal only in the condition, when these users carry out to the spot point in the duration of time, they had chosen.
在此过程中，通过远离独特的常规快照的性能影响，捕获数据的不间断备份用户仅在以下情况下才使用日志，即当这些用户在持续时间内执行到现场时，他们选择了。
The journal of data modification and restored data record can exist on any category of data storage in the system, where there is the proper mentioning of maximum size limits and words of caution.
数据修改和恢复的数据记录的日志可以存在于系统中任何类别的数据存储中，在此适当提及最大大小限制和注意事项。
