Example 1
Embodiment 1 of the present invention provides a cloud space recovery method, as shown in fig. 1, which specifically includes the following steps:
s1, recording user IDs of the first user and the second user respectively;
specifically, the user IDs have uniqueness, and each user ID corresponds to one user;
s2, determining the total available space of the first user and the second user through the user ID;
specifically, determining a total available space corresponding to each user ID;
s3, determining the size of the total available space of the first user and the second user;
specifically, the space size of the total available space of the first user and the second user is determined by querying the mysql database store, for example:
select meta_value from user_meta where meta_key＝‘total_size’and user_id＝XXX；
s4, adding the size of the total available space of the second user into the residual space of the first user, and deleting the total available space of the second user;
wherein the authority of the first user is higher than the authority of the second user;
the total available space of the first user and the second user is composed of used space and residual space.
It is worth mentioning that: in the present embodiment, the total available space is changeable for each user, the change of the allocated space is replaced with the change of the total available space, and the remaining available space can be calculated by the difference between the total available space and the used space, thereby reducing the cost of modifying data per operation, compared with the conventional technique.
Specifically, the size of the total available space of the second user is added to the remaining space of the first user through the scripting language, such as:
update user_meta set meta_value＝XXX where meta_key＝'total_size'and user_id＝XXX。
specifically, the total available space of the second user is deleted by the scripting language, such as:
delete from user_meta where meta_key＝‘total_size’and user_id＝XXX。
more specifically, when a high-authority user (a first user) recovers a low-authority user (a second user), in order to ensure the consistency of the total amount of user space, the total available space of the high-authority user only needs to be increased, the increase is the total available space of the low-authority user, and at this time, the identity of the low-authority user is also recovered and can be recorded in the total available space with high authority.
In a specific embodiment, no matter how many levels of permissions a user is in, once the total available space of the user is reclaimed by a high-permission user, only the total available space of a low-permission user is added to the total available space or the remaining space of the high-permission user who issued the reclaim command.
In S4, deleting the total available space of the second user, specifically:
deleting the total available space of the deleted second user into a recycle bin, and the recycle bin has a revocable function;
in this way, deletion errors can be prevented from failing to recover by the revocable function of the recycle bin.
The cloud space recovery method further comprises the following steps: determining whether the total available space of the user is recycled by judging whether the total available space of the user is accessed within a fixed time, specifically:
judging whether the time when the total available space of the user is not accessed reaches the preset time or not, deleting the total available space of the user to a recycle bin when the time reaches the preset time, and otherwise, reserving the total available space of the user;
wherein the user is a first user or a second user;
in a specific embodiment, the preset time is 5-30 days;
for example, when the preset time is 5 days, and when the total available space of the user is not accessed for 6 days, the total available space of the user is deleted to the recycle bin.
Therefore, when the data in the total available space of the low-authority user is not used for a long time, the data in the total available space can be released after the data in the total available space is deleted through the script language, so that the total available space of the user can be recycled;
the deleted data can be stored in the recycle bin, and the user can be prevented from mistakenly deleting the data through the withdrawal of the recycle bin;
in another embodiment, when the low-authority user is recycled, only the unused space can be recycled, the used space can not be recycled, and the data in the used space continues to be used by the low-authority user.
The method further comprises the following steps: when the first user allocates the total available space of the first user, the total available space of the first user is reduced, the reduced space size is allocated to the created new user by using the script language, and the space size is used as the total available space of the new user.
The method further comprises the following steps: refreshing the total available space of the first user and the second user when the total available space of the first user and the second user changes;
therefore, the data before the change can be prevented from being displayed because the system is not read again after the data change through timely refreshing.
In another embodiment, the cloud space reclamation method further includes: judging whether the total available space of the user reaches saturation in real time, and if so, increasing the total available space of the user; the user is a first user or a second user;
there are three real-time scenarios for increasing the total available space:
a first scheme of adding the total available space of the third user to the total available space of the users whose total available space has reached saturation; the third user is a user with the total available space not accessed for a preset time;
therefore, the space increase of users with insufficient space can be met, and the space of users who do not use the cloud space for a long time can be recycled, so that resources are fully utilized;
a second scheme of adding a reclamation portion reclaimed to the total available space of the first user to the total available space of the users whose total available space has reached saturation;
therefore, the space increase of users with insufficient space can be met, and the problem of space distribution of recovered low-authority users is solved;
according to the third scheme, the residual space of the first user is added into the total available space of the users of which the total available space is saturated;
therefore, the residual space of the first user is directly allocated, the use of the first user for the space is not influenced, and the space of the user with insufficient space can be increased.
In the embodiment, the total available space of each user in the cloud space is limited and managed, so that the problem that the modified space data is excessive at present is solved, and the allocation rate of allocating the total available space to the new user is indirectly increased.
