AI Technical Summary

Benefits of technology

This technology allows for faster restoring of memory devices without requiring an initial reset or duplication process when recovering their original content after being powered down (their own purpose). It also saves up valuable storage space by saving extra copies instead of storing them every few seconds. Additionally, it uses statistic tables that help choose specific times based upon factors like how frequently they are recovered while maintaining good performance over long periods of use. Overall, this method improves efficiency and reliability in protective systems against damage caused due to external sources such as environmental conditions.

Problems solved by technology

This patented technical problem addressed in the patents relates to improving block level CDP technology that can efficiently store important amounts of data while maintaining security measures against loss from overrides such as disk drive crashes caused by excessive memory usage. Current methods require extensive copying of files before they reach restoration times, leading to wasted resources. Additionally, current method requires regular updates after each capture cycle, making them difficult if only partial copies were taken out.

specific Embodiment

[0079] According to the above theory, a data protection system designed combining snapshot and CDP technology is as follows: figure 1 As shown, the client is deployed on the protected computer, and the server is deployed on other computers, but it must be ensured that the computer deployed on the server is stable and reliable. The storage device must be a storage device type supported by the server-side storage management module, and it can also be understood as a dedicated storage device for the data protection scheme. This device must be connected to the protected computer through a dedicated storage network (FC-SAN or iSCSI-SAN). Together.

[0080] The above system is applied to data backup and data recovery.

[0081] The data protection method combining snapshot and CDP technology includes the following implementation steps:

[0082] 1. Install the client on a SQL Server host A, deploy the server on host B, and connect the dedicated storage device C and host A through a ...

Abstract

The present invention relates to a continuous data protection system and method combining with a snapshot technology. The system comprises a client, a server side, a specialized storage device which can be communicated with each other through a network, and the method combines instantaneous recovery properties of the snapshot storage and I / O level of fine grain recovery properties of a block-level CDP technology. The method is applied to data backup and data recovery. Compared with the prior art, the continuous data protection system and method disclosed by the present invention have advantages such as saving time, saving a storage space, and the like.
