Title:
DATA BACKUP METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/211099
Kind Code:
A1
Abstract:
Disclosed are a data backup method and apparatus. The method comprises: determining an application requiring data backup, and determining at least one storage device storing data of the application (S200); freezing disk IO corresponding to each of the at least one storage devices (S210); for each of the at least one storage devices, instructing a backup device to perform data backup for the application (S220); and after determining that the backup device has completed data backup for the application, restoring disk IO corresponding to each storage device (S230). In the present invention a host agent ensures consistency of application data by freezing disk IO. The backup device only needs to interface with the host agent via a standard southbound interface, and does not need to carry out specific backup pre-processing and backup post-processing actions for an upper-layer application, thus reducing the complexity and improving efficiency of data backup.
