Cinder-based multi-back-end storage method

The invention relates to the technical field of cloud computing, and particularly provides a cinder-based multi-back-end storage method, which comprises the following steps: S1, creating a backupType:binding with a storage strategy of a storage back end, and selecting the storage strategy used by the storage back end to create the backup by specifying the backupType when creating the backup; S2,registering the information contained in the backupType into a service table; S3, scheduling from the backup to a storage medium; S4, adding a backupType into the cinder database; S5, modifying host value of the cinder backup to be host@backend in a service table; S6, creating a backup and assigning backupType and az; S7, calling back_end name associated with the az and the backhaul Type to cinder-backup by cinder; and S8, selecting a storage strategy by cinder- backup according to the storge_policy associated with the backup Type. Compared with the prior art, the invention has the advantagesthat different storage stra
