Problems solved by technology
At present, snapshots are generally created in the way of complete replication, which creates a large amount of data, takes up more storage space, and is relatively inefficient; moreover, it cannot provide evidence-based information for subsequent operations such as recovery and deletion , making the processing efficiency of recovery, deletion and other operations slow, which is not conducive to snapshot management and slow management efficiency

The invention discloses a snapshot management method, which comprises the following steps: receiving a snapshot management request sent by a user; judging the type of snapshot management request, wherein the snapshot management request is any one or combination of a creation request, a deletion request and a recovery request; when the snapshot management request is a create request, determining target data corresponding to the create request, creating the target snapshot of the target data by using incremental snapshot technology and preset creation strategy, compressing the target snapshot, and recording the log information of the target snapshot. The log information includes the storage address of the target data, the storage address and the snapshot data of the target snapshot, and thecreation timestamp. The method can improve the speed of snapshot creation, reduce the memory consumption of snapshot, provide good queryable information for other subsequent operations, and improve the processing efficiency of other subsequent operations, so as to improve the management efficiency of snapshot.
Description
technical field [0001] The present invention relates to the technical field of data storage, and more specifically, to a snapshot management method, system, device, equipment and readable storage medium. Background technique [0002] In the field of data storage, snapshots are an indispensable function in online storage systems. It can perform online data backup and recovery, and provide storage users with an alternate data access channel. [0003] Snapshot management generally includes operations such as creating, restoring, and deleting. Among them, operations such as restoring and deleting snapshots are performed based on information generated during the creation operation. Therefore, creating a snapshot is the first step in snapshot management. At present, snapshots are generally created in the way of complete replication, which creates a large amount of data, takes up more storage space, and is relatively inefficient; moreover, it cannot provide evidence-based informat...
