Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
Example one
According to an embodiment of the present invention, a data storage method is provided. Fig. 1 is a flow chart of a data storage method according to a first embodiment of the invention.
Step S110, when storing the data to be stored, detecting the proportion of the unused space in the storage device to the storage space.
Unused space, i.e. unused storage space.
The proportion of the unused space in the storage space is unused space/storage space.
Step S120, when the proportion of the unused space in the storage space is smaller than a preset proportion threshold, determining the available space of the storage device according to the data volume of the data to be stored.
And the proportion threshold is used for measuring whether the storage device has enough space to store data. The ratio threshold may be an empirical value or an experimentally obtained value.
The occupiable space refers to a space in the storage space of the storage device, which can be used for storing the data to be stored. In other words, occupiable space refers to storage space that may be occupied by new data.
The occupiable space may be a portion of the storage space where no data is stored, or a portion of the storage space where data is stored plus a portion of the storage space where no data is stored.
Step S130, storing the data to be stored in the occupiable space.
In this embodiment, the amount of data that can be stored in the occupiable space is equal to the amount of data to be stored.
In this embodiment, the available space is a space where no data is stored or a space where data is already stored. Data that has been stored is data that can be deleted or migrated.
Further, the occupiable space comprises: a storage space occupied by data stored earliest to the storage device; and/or a storage space occupied by data stored in the storage device within a first preset time period. The first preset time period may be a few days per month, a few hours per day. For example: the movie is downloaded on the first day of each month and the first time period may be set to the first day of each month.
When the occupiable space stores data, storing the data to be stored to the occupiable space, including: using the data to be stored to cover the data stored in the occupiable space; or, the data stored in the occupiable space is firstly cached to a preset caching device, and then the data to be stored is stored in the occupiable space. For example: the user downloads a new video, and the new video data can be made to overwrite the data stored in the occupiable space, or the video stored in the occupiable space before is moved out to the cache device, and the new video is stored in the moved-out position.
In this embodiment, when the space of the storage device is insufficient, if the data is to be stored, the available space in the storage device is determined according to the data amount of the data to be stored, and then the data to be stored is stored in the available space. According to the embodiment, the data can be intelligently stored without manually deleting the data, and the data to be stored can be stored into the storage device all the time.

Step S220, judging whether the proportion of the unused space in the storage space is smaller than a preset proportion threshold value; if yes, go to step S230; if not, step S270 is executed.
The proportion of the unused space occupying the storage space is smaller than the proportion threshold value, which can indicate that the unoccupied storage space is insufficient, and the situation that the data cannot be stored in the storage space occurs at any time.
For example: the threshold value of the ratio is 20%. The unused space of the storage device is detected, the proportion of the unused space to the storage space is determined, and when the proportion is less than 20%, the determination of the available space in the storage space is started.
Step S230, if the ratio of the unused space to the storage space is smaller than a preset ratio threshold, determining an available space of the storage device according to the data size of the data to be stored.
In this embodiment, the amount of data that can be stored in the occupiable space is equal to the amount of data to be stored.
An occupiable space comprising: a storage space occupied by data stored earliest to the storage device; and/or a storage space occupied by data stored in the storage device within a first preset time period.
Step S240, judging whether to use the data to be stored to cover the data stored in the occupiable space according to the selected data covering option; if yes, go to step S250; if not, step S260 is performed.
A data overlay selection for prompting a user whether to overlay data stored in the occupiable space.
A data overlay selection comprising: an override option and an override-not option. If the override option is selected, perform step S250; if the not-override option is selected, step S260 is performed.
And step S250, covering the data stored in the occupied space by using the data to be stored.
Step S260, after a second time period is preset, the data to be stored is transferred to the storage device for storage.
Step S270, if the proportion of the unused space in the storage space is greater than or equal to a preset proportion threshold value, storing the data to be stored in the storage device.
Further, the data to be stored is stored in the unused space of the storage device. And the data amount which can be stored in the unused space is larger than that of the data to be stored.
As shown in fig. 3, after a second time period is preset, the method for transferring the data to be stored to the storage device for storage includes the following steps:
in step S310, the ratio of the unused space in the storage device to the storage space is detected.
Step S320, judging whether the proportion of the unused space in the storage space is smaller than a proportion threshold value; if yes, go to step S330; if not, step S340 is performed.
And after the second time period is preset, determining the proportion of the unused space in the storage space again, wherein the purpose of determining whether the unused space is sufficient after the second time period is achieved.
Step S330, if the proportion of the unused space in the storage space is smaller than the proportion threshold, firstly caching the data stored in the occupiable space to a preset caching device, and then storing the data to be stored in the occupiable space.
Step S340, if the ratio of the unused space to the storage space is greater than or equal to the ratio threshold, storing the data to be stored in the storage device.
In this embodiment, after the data stored in the available space is cached in the caching device, if the caching time of the data reaches a preset time length, the data is cleared in the caching device.
