Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the storage system, remote copy is to establish a backup relationship between two systems, and by this technique, the disk data on system a can be synchronously copied to the disk data on system B. The disk data is uploaded to a cloud server. However, the conventional cloud-on disk data cannot be combined with remote copy because when the disk data is cloud-on, it is required to ensure that the current disk data is not changed, and the disk data is changed at any time by remote copy, which causes the disk data to be changed, so that the remote copy and the cloud-on disk data cannot be executed at the same time, and the cloud-on efficiency of the disk data under remote copy is low. The disk data cloud-up method provided by the application can improve the cloud-up efficiency of disk data under remote copy.
Referring to fig. 1, fig. 1 is a first flowchart of a method for cloud-on-disk data according to an embodiment of the present disclosure.
The method for cloud loading of disk data provided by the embodiment of the application is applied to a storage system with a remote copy function, and comprises the following steps:
step S101: and acquiring target disk data to be clouded.
In practical application, the storage system may obtain target disk data to be clouded first, where the target disk data may be part of disk data in an externally specified storage system, or may be all disk data in the storage system. The size and specific type of the target disk data can be flexibly determined according to actual needs.
Step S102: and recording the data information of the current target disk data to obtain backup disk data.
In practical application, after the storage system acquires the target disk data, the storage system can record the data information of the current target disk data to obtain the backup disk data. The current data information of the target disk data refers to data information of the target disk data when the target data is subjected to the cloud-up operation. Specifically, the data information of the current target disk data may be copied to obtain the backup disk data.
In a specific application scenario, in order to improve the efficiency of obtaining backup disk data and further improve the cloud-up efficiency of the disk data provided by the application, a snapshot technology may be adopted to record data information of current target disk data.
In a specific application scenario, in the process of uploading backup disk data to a cloud server, new disk data may exist in target disk data, for example, new disk data obtained by remote copying or new disk data transmitted through a transmission port of a storage system, so that the target disk data changes, and in the process of uploading, the backup disk data does not change along with the change of the target disk data, so that after the backup disk data is uploaded to the cloud server, the disk data in the cloud server is not synchronized with the target disk data, and in order to achieve data synchronization between the cloud server and the target disk data, after the storage system obtains the backup disk data, before the backup disk data is uploaded to the cloud server, whether new disk data exists in the target disk data can also be judged; if so, recording corresponding data information of the new disk data to obtain new backup disk data; correspondingly, after the backup disk data is uploaded to the cloud server, new backup disk data needs to be uploaded to the cloud server.
In a specific application scenario, in order to reduce the recording difficulty of recording the corresponding data information of the new disk data, the step of recording the corresponding data information of the new disk data by the storage system may specifically be: and recording the data information of the current new target disk data. That is, the storage system records the whole data information of the current new target disk data. The process of determining the new disk data in the new disk data is avoided, and the implementation difficulty in data recording is reduced.
In a specific application scenario, in order to save time consumed for recording the corresponding data information of the new disk data and improve recording efficiency, the step of recording the corresponding data information of the new disk data by the storage system may specifically be: and recording the new disk data and the change condition of the target disk data after receiving the new disk data, so that the cloud server updates the target disk data stored in the cloud server according to the new disk data and the change condition.
It should be noted that the present application does not limit the specific way in which the storage system records the corresponding data information of the new disk data, specifically, a preset data quantity value may be set, and it is determined whether the data quantity of the new disk data is greater than or equal to the preset data quantity value, if so, the storage system may record the data information of the current new target disk data, and if not, the storage system may record the new disk data and the change condition of the target disk data after receiving the new disk data.
Step S103: and uploading the backup disk data to a cloud server.
In practical application, after the storage system obtains the backup disk data, the backup disk data can be uploaded to a cloud server, that is, the cloud uploading process of the backup disk data.
In a specific application scenario, in order to facilitate the external understanding of the progress of the cloud process of the backup disk data, the storage system can also query the progress of uploading the backup disk data in the process of uploading the backup disk data to the cloud server; and sending the uploading progress to the user client. The user can know the cloud progress of the backup disk data by means of the user client, so that the tasks of the storage system can be planned correspondingly. Specifically, the storage system can also directly display the cloud progress of the backup disk on a display screen of the storage system.
In a specific application scenario, in order to trace the cloud loading process of the target disk data subsequently, for example, trace a specific reason when the target disk data uploaded to the cloud server has an error, the storage system records the data information of the current target disk data, and after obtaining the backup disk data, may also record the backup disk data and the time for obtaining the backup disk data.
The method for cloud loading of the disk data is applied to a storage system with a remote copy function, and target disk data to be cloud loaded are obtained; recording data information of current target disk data to obtain backup disk data; and uploading the backup disk data to a cloud server. According to the disk data cloud method, after target disk data to be clouded is obtained, the target disk data is not clouded, but data information of the current target disk data is recorded to obtain backup disk data, and then the backup disk data is uploaded to the cloud server.
Referring to fig. 2, fig. 2 is a second flowchart of a method for cloud-on-disk data according to an embodiment of the present application.
In practical application, the method for cloud loading of disk data provided by the embodiment of the present application may include the following steps:
step S201: and acquiring target disk data to be clouded.
Step S202: and recording the data information of the current target disk data by adopting a snapshot technology to obtain backup disk data.
Step S203: and judging whether the target disk data contains new disk data, if so, executing step S204.
Step S204: and judging whether the data volume of the new disk data is greater than or equal to the preset data volume value, if so, executing step S205, and if not, executing step S206.
Step S205: and recording the data information of the current new target disk data to obtain new backup disk data.
Step S206: and recording the new disk data and the change condition of the target disk data after receiving the new disk data to obtain new backup disk data.
Step S207: and uploading the backup disk data to a cloud server, and uploading the new backup disk data to the cloud server.
Step S208: and recording the backup disk data and the time for obtaining the backup disk data.
Step S209: and inquiring the uploading progress of the backup disk, and sending the uploading progress to the user client.
