Abstract

The embodiment of the present invention discloses a method and a device for converting a copy mode in a data backup system, which relate to the field of communication technology and can solve the problem that the currently implemented backup mode is not suitable for the current scene and brings inconvenience to the normal operation of the system. The method of the present invention includes: the current storage array determines the current input / output I / O write mode, and the I / O write mode includes asynchronous replication mode, active-standby AP mode and dual-active AA mode; the current storage array determines the target parameter , the target parameter represents the performance of the current storage array I / O processing under the current I / O write mode; the current storage array judges whether the target parameter reaches a preset standard; if the target parameter reaches According to the preset standard, the current storage array converts the current I / O write mode into the target I / O write mode.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for converting a duplication mode in a data backup system. Background technique [0002] In order to deal with the data loss problem caused by disasters, data backup technology has been widely used. Both remote replication and active-active are mainly used for disaster recovery and backup of system-level data. Remote replication includes synchronous remote replication and asynchronous remote replication. backup and load balancing. For different application scenarios, you can choose the data backup mode corresponding to the application scenario, for example, asynchronous remote replication mode, AP (Active Prepare, active-standby) mode and AA (Active-Active, active-active) mode, etc. Array disaster recovery and backup scenarios. In the specific implementation process, no matter what kind of disaster recovery backup method is used, it has its own adva...
