Problems solved by technology
[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the traditional CDP backup technology, or depends on the network bandwidth between the backup target machine and the backup server, so it cannot be applied to remote disaster recovery; or requires Additional local cache disk, if there is no additional disk on the backup target machine, the continuous data protection scheme cannot be implemented or external storage is required to provide the cache disk
This makes continuous data protection less convenient

Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] The continuous data protection method without local cache provided by this application can be applied to such as figure 1 shown in the application environment. The application environment includes a backup target machine 101 and a backup server 102, and the backup target machine 101 and the backup server 102 can communicate through a network. The target backup machine 101 refers to a device that needs to back up data, and the backup server 102 is a server that backs up data on the target backup machine 101 . The backup target machine 101 acquires the incremental metadata, reads the increme...

The invention relates to a continuous data protection method and system without local cache, and belongs to the technical field of networks. The method includes: obtaining a data backup request; obtaining incremental metadata according to the data backup request; wherein, the incremental metadata is used to describe incremental data; and reading corresponding the incremental data; sending the read incremental data to the backup server, so as to trigger the backup server to back up the incremental data. The above technical solution solves the problem that the continuous data protection is not convenient enough. The space occupied by incremental metadata is small, and the memory of the target backup machine is sufficient to store incremental metadata, so no additional local cache is required, which makes continuous data protection more convenient.
Description
technical field [0001] The invention relates to the field of network technology, in particular to a continuous data protection method, system, computer equipment and storage medium without local cache. Background technique [0002] Continuous Data Protection (CDP, Continual Data Protection) is a real-time backup technology based on disk block devices. The backup target function can encapsulate IO (Input / Output, input and output) requests as monitoring records and send them to the backup server. Different from the scheduled backup method, the CDP backup technology protects data at the IO level or millionth of a second level. In addition, when a failure or disaster occurs, the user can precisely select the time point for data recovery, which can minimize data loss (RPO, Recovery Point Object). [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the traditional CDP backup technology, o...
