Referring to fig. 1, a data synchronization method provided by the present invention uses a computer device as an execution main body, and is used for solving a problem that in a conventional file indexing technology, when a file is changed, the index information of the file is directly modified. The direct modification mode has the technical problems that the modification operation of the index does not generate corresponding records, the operation is difficult when the index information is synchronized among multiple devices, and the synchronization efficiency is low. In one embodiment, the data synchronization method includes the steps of:
s11, when the index information of the file is monitored to be changed, obtaining a change record of the index information;
s12, storing the change records into a pre-constructed file list, updating the original version number of the file list to obtain a change version number, and storing the change version number into the pre-constructed version list; the file list is used for storing change records generated when a user changes a file, and the version list is used for storing the version number of the file list;
s13, when it is monitored that the target device needs to synchronize the index information of the file, acquiring the version number of a file list adopted by the target device in the last synchronization, and judging whether the version number is consistent with the change version number;
and S14, if not, acquiring a file list corresponding to the change version number to obtain a target file list, and sending the target file list to the target equipment so that the target equipment completes synchronous change according to the change record of the target file list.
In this embodiment, in order to solve the problem of file index synchronization among multiple devices and record the change records of files, when it is monitored that the index information of any file is changed, the embodiment may initialize a file list for storing the change records generated when a user changes the file, so that the index information is not directly modified, but a change record of the index information is generated and the change record is recorded in the file list; wherein, the change record stores the changed index information. When other equipment needs to synchronize the index information of the file, the synchronization can be completed only by acquiring new file index information from the address of the index information of the file acquired last time, so that the synchronization process is simplified, and the synchronization efficiency is improved.
Specifically, when the computer device monitors that the index information of the file is changed, for example, a new file, a new folder, a modified file name, a deleted file or a reconstructed file list and the like, the computer device obtains a change record of the index information, stores the change record into a pre-constructed file list, updates an original version number of the file list to obtain a change version number, and stores the change version number into a pre-constructed version list. For example, when a user modifies a file name, a modification record for modifying the file name is generated, the record is recorded in a file list, an original version number of the file list is acquired, the original version number is updated to obtain a modified version number, and the modified version number is used as a new version number of the file list. When updating, 1 can be added on the basis of the original version number as a modified version number, and if the original version number is a first version, the modified version number is a second version.
When the target equipment needs to synchronize the index information of the file, the version number of a file list adopted by the target equipment in the last synchronization is obtained, whether the version number is consistent with the change version number is judged, if yes, synchronous change is not needed to the target equipment, if not, the file list corresponding to the change version number is obtained, the target file list is obtained, and the target file list is sent to the target equipment, so that the target equipment completes synchronous change according to the change record of the target file list. For example, when the file of the computer device completes the change of the modified file name, a change record of the modified file name is generated and stored in the target file list, and the target device modifies the file name of the file according to the change record of the target file list to complete the synchronous change.
The following takes the example of a reconstructed file list: when the modified version number of the file list of the server is larger than the version number of the file list of the target device, the target device needs to reset the local file list, and then pulls the target file list from the server again, so that the effect that the version data information of the local file list and the version data information of the file list of the server are consistent is achieved.
The version list is a record of the version of the entire file list of the user, and mainly stores the version number of the change of the target file list and the version number of the current file list. The change version number is the total version of the latest file list.
The file list mainly records user operation records on files, wherein the record records specify some types and some operation information, such as: create files, create folders, rename, delete files, etc. The information recorded in the file list is information about specific operations of the user on the file, and the information plays an important role in guiding the operation record of tracing the file and can also expand a lot of information.
The data synchronization method provided by the invention comprises the steps of acquiring the change record of index information when the change of the index information of a file is monitored, storing the change record into a pre-constructed file list, updating the original version number of the file list to obtain a change version number, storing the change version number into the pre-constructed version list, acquiring the version number of the file list adopted by target equipment during the last synchronization when the index information of the file is monitored to be synchronized by the target equipment, judging whether the version number is consistent with the change version number, if not, acquiring the file list corresponding to the change version number to obtain a target file list, sending the target file list to the target equipment so that the target equipment completes the synchronous change according to the change record of the target file list, managing the change records of all files by using the file list, managing the change version number of the file list by using the version list, when the equipment needs to be synchronously changed, the change records are quickly found according to the file list and the version list, and the target equipment is synchronously changed, so that the synchronization of the index information among the multiple equipment is simplified, and the synchronization efficiency is improved.
Further, before the step of storing the change record in a pre-constructed file list, the method may further include:
acquiring the change type of the file;
constructing a corresponding file list according to the change type of the file; wherein, each file list correspondingly stores a change record of a change type.
The embodiment acquires the change type of the file; preferably, the change types include a new file, a new folder, a modified file name, or a deleted file, a corresponding file list is constructed according to the change types of the files, and each file list correspondingly stores a change record of one change type. For example, when a user modifies a file name of a file, a file list storing change records of a change type of the modified file name is constructed, so that management of the change records is facilitated, and data search is facilitated.
Further, after the step of determining whether the version number is consistent with the change version number, the method may further include:
when the version number of a file list adopted by the target equipment in last synchronization is judged to be smaller than the change version number, deleting the synchronization file of the target equipment, executing to obtain a file list corresponding to the change version number to obtain a target file list, and sending the target file list to the target equipment so that the target equipment completes the step of synchronous change according to the change record of the target file list; the synchronous file is a file which needs to be synchronously changed when the target equipment is synchronized last time.
In this embodiment, the version number of the file list adopted by the target device in the last synchronization is obtained, the version number of the file list adopted in the last synchronization is compared with the change version number to obtain a comparison result, when it is determined according to the comparison result that the version number of the file list adopted in the last synchronization of the target device is smaller than the change version number, the synchronization file of the target device is deleted, the synchronization file is a file that needs to be synchronously changed in the last synchronization of the target device, the file list corresponding to the change version number is obtained, the target file list is obtained, and the target file list is sent to the target device, so that the target device completes the synchronous change according to the change record of the target file list, and the timely synchronous change of the target device is realized.
For example, when the version number of the file list adopted in the last synchronization of the target device is the first version, the file list in the server is inquired, and the latest change version number is determined to be the second version, the file list with the version number of the target device being the first version is deleted, the file list with the change version number being the second version is pulled from the server, the target file list is obtained, and the synchronous change is completed by using the change record of the target file list.
In an embodiment, the step of completing the synchronous change according to the change record of the target file list may specifically include:
extracting the change type of the file from the change record;
when the change type is determined to be a deleted file, deleting the synchronous file of the target equipment, and recording the version number of the deleted synchronous file;
and when the change type is determined to be a new file, the file is newly built on the target equipment, and the version number of the newly built file is recorded.
In this embodiment, the version number of the target device is compared with the change version number of the server, if the version number of the target device is smaller than the change version number of the server, the file list of the target device needs to be completely cleared, the entire file list corresponding to the change version number is pulled from the server again to obtain a target file list, a change record is extracted from the target file list, the change type of the file is extracted from the change record, when the change type is determined to be a deleted file, the synchronization file of the target device is deleted, the version number of the deleted synchronization file is recorded, when the change type is determined to be a new file, the file is newly created at the target device, and the version number of the newly created file is recorded, so that the version number of the target device and the change version number of the server are kept consistent.
In an embodiment, the step of updating the original version number of the file list to obtain a modified version number may specifically include:
and updating the original version number of the file list once when monitoring that the file list stores one change record every time to obtain a change version number.
In this embodiment, when it is monitored that each time a change record is stored in the file list, the original version number of the file list is updated once, so as to obtain a change version number. For example, when it is monitored that the file list is stored in a change record, the original version number of the file list is obtained, 1 may be added on the basis of the original version number as a change version number, and if the original version number is a first version, the change version number is a second version.
Further, after the step of determining whether the version number is consistent with the change version number, the method may further include:
and when the version number is judged to be consistent with the change version number, synchronous change of the target equipment is not required.
In this embodiment, when the version number is determined to be consistent with the change version number, synchronous change of the target device is not required, until the version number is determined to be inconsistent with the change version number, the file list with the largest version number is pulled from the server to obtain a target file list, and the target file list is sent to the target device, so that the target device completes synchronous change according to the change record of the target file list. For example, when the file of the computer device completes the change of the modified file name, a change record of the modified file name is generated and stored in the target file list, and the target device modifies the file name of the file according to the change record of the target file list to complete the synchronous change.
Referring to fig. 2, an embodiment of the present invention further provides a data synchronization apparatus, and in an embodiment, the data synchronization apparatus includes an obtaining module 11, a storing module 12, a determining module 13, and a sending module 14.

In this embodiment, in order to solve the problem of file index synchronization among multiple devices and record the change records of files, when it is monitored that the index information of any file is changed, the embodiment may initialize a file list for storing the change records generated when a user changes the file, so that the index information is not directly modified, but a change record of the index information is generated and the change record is recorded in the file list; wherein, the change record stores the changed index information. When other equipment needs to synchronize the index information of the file, the synchronization can be completed only by acquiring new file index information from the address of the index information of the file acquired last time, so that the synchronization process is simplified, and the synchronization efficiency is improved.
Specifically, when the computer device monitors that the index information of the file is changed, for example, a new file, a new folder, a modified file name, a deleted file or a reconstructed file list and the like, the computer device obtains a change record of the index information, stores the change record into a pre-constructed file list, updates an original version number of the file list to obtain a change version number, and stores the change version number into a pre-constructed version list. For example, when a user modifies a file name, a modification record for modifying the file name is generated, the record is recorded in a file list, an original version number of the file list is acquired, the original version number is updated to obtain a modified version number, and the modified version number is used as a new version number of the file list. When updating, 1 can be added on the basis of the original version number as a modified version number, and if the original version number is a first version, the modified version number is a second version.
When the target equipment needs to synchronize the index information of the file, the version number of a file list adopted by the target equipment in the last synchronization is obtained, whether the version number is consistent with the change version number is judged, if yes, synchronous change is not needed to the target equipment, if not, the file list corresponding to the change version number is obtained, the target file list is obtained, and the target file list is sent to the target equipment, so that the target equipment completes synchronous change according to the change record of the target file list. For example, when the file of the computer device completes the change of the modified file name, a change record of the modified file name is generated and stored in the target file list, and the target device modifies the file name of the file according to the change record of the target file list to complete the synchronous change.
The following takes the example of a reconstructed file list: when the modified version number of the file list of the server is larger than the version number of the file list of the target device, the target device needs to reset the local file list, and then pulls the target file list from the server again, so that the effect that the version data information of the local file list and the version data information of the file list of the server are consistent is achieved.
The version list is a record of the version of the entire file list of the user, and mainly stores the version number of the change of the target file list and the version number of the current file list. The change version number is the total version of the latest file list.

when the version number of a file list adopted by the target equipment in last synchronization is judged to be smaller than the change version number, deleting the synchronization file of the target equipment, executing to obtain a file list corresponding to the change version number to obtain a target file list, and sending the target file list to the target equipment so that the target equipment completes the step of synchronous change according to the change record of the target file list; the synchronous file is a file which needs to be synchronously changed when the target equipment is synchronized last time.
5. The data synchronization method of claim 4, wherein the step of completing the synchronized change according to the change log of the target file list comprises:
extracting the change type of the file from the change record;
when the change type is determined to be a deleted file, deleting the synchronous file of the target equipment, and recording the version number of the deleted synchronous file;
and when the change type is determined to be a new file, the file is newly built on the target equipment, and the version number of the newly built file is recorded.
6. The data synchronization method according to claim 1, wherein the step of updating the original version number of the file list to obtain a modified version number comprises:
and updating the original version number of the file list once when monitoring that the file list stores one change record every time to obtain a change version number.
7. The data synchronization method according to claim 1, wherein after the step of determining whether the version number is consistent with the change version number, the method further comprises:
and when the version number is judged to be consistent with the change version number, synchronous change of the target equipment is not required.
8. A data synchronization apparatus, comprising:
the acquisition module is used for acquiring a change record of index information when the change of the index information of a file is monitored;
the storage module is used for storing the change records into a pre-constructed file list, updating the original version number of the file list to obtain a change version number, and storing the change version number into the pre-constructed version list; the file list is used for storing change records generated when a user changes a file, and the version list is used for storing the version number of the file list;
the judging module is used for acquiring the version number of a file list adopted by the target equipment in last synchronization when the situation that the target equipment needs to synchronize the index information of the file is monitored, and judging whether the version number is consistent with the change version number or not;
and the sending module is used for acquiring a file list corresponding to the change version number when the version number is judged to be inconsistent with the change version number, obtaining a target file list, and sending the target file list to the target equipment so that the target equipment completes synchronous change according to the change record of the target file list.
