The data processing method of the present application is further described below, and as shown in fig. 3, the data processing method of the present application may include:
step S201, after receiving a cloud hard disk deletion request issued by a user, acquiring that the type of the deletion request is soft deletion;
step S202, acquiring the ID of the cloud hard disk to be deleted from the deletion request;

Step S203, checking the user authority and the like of the deletion request, and executing step S204 if the user authority and the like pass the verification; if the verification is not passed, the flow is ended;
step S204, in the render database, according to the ID of the cloud hard disk to be deleted, setting the value of a soft deleted mark (soft _ deleted) of the cloud hard disk record to be deleted as True (or 1), and not modifying the value of an original deleted mark (deleted) of the cloud hard disk record;
in this example, the default value of the original deletion flag may be set to False (or 0), and in this step, since the value of the original deletion flag is not modified, the value of the original deletion flag is also False (or 0).
It should be noted that, in this example, the logical values of the soft deletion flag and the original deletion flag may be set in the form of True/False, or may be set in the form of 1/0. In other examples, other rules may be set to identify whether to perform a complete deletion.
Step S205, executing soft deletion operation of the cloud hard disk;
in this example, the soft deletion operation of the cloud hard disk includes: and releasing the quota corresponding to the item (or tenant) to which the cloud hard disk belongs, and reserving the data on the bottom storage device corresponding to the cloud hard disk.
Where a quota may include the amount and capacity of resources allocated to an item.
In an example, after the soft deletion is performed on the cloud hard disk, when a user views data in the OpenStack system, the information of the cloud hard disk may not be displayed any more, or the corresponding information of the cloud hard disk may be displayed by adding a mark or a special color (e.g., grayscale), and at this time, although the information of the soft deleted cloud hard disk is displayed, the data of the cloud hard disk is unavailable.
Step S206, after receiving a cloud hard disk recovery request issued by a user, acquiring the ID of the cloud hard disk to be recovered from the recovery request;
step S207, checking the user authority and the like of the recovery request, and executing step S208 if the user authority and the like pass the verification; if the verification is not passed, the flow is ended;
step S208, if the logic value of the soft deletion mark corresponding to the cloud hard disk is True (or 1) and the logic value of the original deletion mark corresponding to the cloud hard disk is False, setting the logic value of the soft deletion mark corresponding to the cloud hard disk to be False (or 0), keeping the current logic value of the original deletion mark corresponding to the cloud hard disk unchanged, and performing recovery operation on the cloud hard disk;
the recovery request may carry a cloud disk identifier, and the corresponding cloud disk record may be found according to the cloud disk identifier.
Step S209, after receiving a cloud hard disk deletion request issued by a user, acquiring that the type of the deletion request is forced deletion;
step S210, acquiring the ID of the cloud hard disk to be deleted from the deletion request;
step S211, checking the user authority and the like of the deletion request, and executing step S212 if the user authority and the like pass the verification; if the verification is not passed, the flow is ended;
step S212, in a render database, setting the value of an original deletion identifier (deleted) of the cloud hard disk record to be deleted as True (or 1) according to the ID of the cloud hard disk to be deleted;
and step S213, executing forced deletion operation of the cloud hard disk.
In this example, the forced deletion operation of the cloud hard disk includes: and releasing the quota corresponding to the item to which the cloud hard disk belongs, and deleting the data on the bottom storage device corresponding to the cloud hard disk.
In the application, the soft deletion of the cloud hard disk can be realized by only setting a soft deletion mark for the cloud hard disk record in the database without cleaning the bottom-layer stored data, so that the recovery of subsequent data can be supported. The soft deletion mechanism of the cloud hard disk may be that when the cloud hard disk is deleted, a field, that is, a soft deletion flag, is added to each cloud hard disk record subjected to soft deletion in the sender database, and the value of the soft deletion flag is set to True (True or 1) to identify that the cloud hard disk has been soft deleted, but the cloud hard disk data on the underlying storage device is temporarily retained.
If the user needs to restore the data within a period of time, the value of the soft deletion flag recorded by the cloud hard disk which is subjected to soft deletion can be modified to be False (False or 0), so that the cloud hard disk can receive the management of the sender service again.
If the user really needs to thoroughly clean the cloud hard disk, the data can be forcibly deleted, and the bottom data can be really cleaned.
It should be noted that the execution steps of the above operations are only examples, and in other embodiments, the execution sequence of steps S201, S205, and S207 is not limited, and the execution sequence of steps S202 to S204, step S206, and step S208 to step S210 is not limited. In other embodiments, a request for soft deletion, a request for forced deletion, or a request for recovery may be received in any order according to a specific scenario, and an operation corresponding to the request may be started after the request is received.
By the technical scheme, the deleted cloud hard disk data can be effectively recovered, the mistaken deletion is avoided, and therefore the usability and the convenience of a user in the using process are effectively improved.
