Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the invention, the file system is initialized before being started, and the delayed WORM mode of the file system is set to be the maximum delay mode or the appointed delay mode. The maximum delay mode refers to: the file is kept in a modifiable state until the recording system selects the file stored by the file system for recording. In the maximum delay mode, if the target modification file is not recorded, the target modification file is in a modifiable state; if the target modification file is recorded, the target modification file is in an unmodified state. The specified delay pattern refers to: the file system stores the file in a modifiable state for a specified delay time, and switches to an unmodified state once the specified delay time is exceeded.
Fig. 1 is a flowchart of a file processing and recording method according to a first embodiment of the present invention.
S101, the file system receives a modification request sent by a user side and determines a target modification file of the modification request.
In one embodiment, after the file system receives the access request, the access request may be parsed to obtain request information, where the request information includes at least: request flags, target files for the request, etc. The file system may determine the request type of the access request based on the request flag, including a modify request, a read request, and the like.
In one embodiment, the access request sent by the user terminal may be a modification request or a read request. The file system may receive different request types and perform corresponding read, write, etc. operations. The process of receiving a read request by the file system will be described in detail in fig. 2, and will not be described in detail here.
S102, the file system determines the modifiable state of the target modification file according to the delayed WORM mode of the file system so as to send a modification request to the target modification file for modification.
In one embodiment, the delayed WORM mode of the file system may be a maximum delay mode or a specified delay mode. In these two different delayed WORM modes, the specific process of determining the target modified file recording status by the file system will be described in detail in FIGS. 3 and 5, which are not repeated here.
S103, the recording system designates the target recording file, and determines the recording state of the target recording file according to the delayed WORM mode of the file system so as to record the target recording file.
In one embodiment, when the files stored in the file system reach a certain amount, the recording system is automatically triggered to perform the recording operation. For example, when the size of the file stored in the file system exceeds the capacity of one optical disc, the recording system selects the file for recording. Before the recording system performs the recording operation on the file, whether the file meets the recording condition is determined according to the read-write flag bit of the file. The user can set the basis for triggering the recording operation and selecting the target recording file according to the requirement, and the invention is not limited to the above.
In one embodiment, when the delayed WORM mode of the file system is the maximum delay mode or the specified delay mode, the specific process of determining the recording status of the target recording file will be described in detail in FIG. 4 and FIG. 6, and will not be described in detail here
It should be noted that the method for processing and recording files in a delayed WORM mode of the present invention is not only applicable to optical disc library storage systems, but also applicable to various recording storage systems, which is not limited in this invention.

In one embodiment, after the recording system records the file, a recording mark is added to the recorded file, and the position of the recorded file is recorded. In this step, if the target modification file has a recording mark, the file is recorded, i.e. the target modification file is in an unmodified state, and S303 is executed; if the target modification file has no recording mark, the file is not recorded, i.e. the target modification file is in a modifiable state, and S304 and S305 are executed.
S303, the file system feeds back to the user terminal that the file is in an unmodified state, and the modification request fails.
S304, the file system marks the target modification file as a modification state, and sends a modification request to the target modification file for modification.

The file system may obtain the latest modification time of the target modification file from the metadata of the target modification file.
S503, whether the time interval between the latest modification time and the current time is greater than the specified delay time.
In one embodiment, the time interval between the latest modification time and the current time is compared with a specified delay time to learn the modifiable state of the target modification file. For example, the specified delay time set by the user is 1 hour, and the latest modification time is 2018, 7, 10, and 10:00. If the current time is 2018, 7, 10 and 10:20, and the time interval between the latest modification time and the current time is 20 minutes and is smaller than the designated delay time, the target modification file is in a modifiable state; if the current time is 2018, 7, 10, 11:20, and the time interval between the latest modification time and the current time is 1 hour and 20 minutes, and is greater than the designated delay time, the target modification file is in an unmodified state. The user can set the specified delay time as needed, which is not limited by the present invention.
In this step, if the time interval between the latest modification time and the current time is greater than the specified delay time, S504 is executed; if the time interval between the latest modification time and the current time is smaller than the specified delay time, S505 and S506 are executed.
