Specifically, the method for recovering the recycle bin to delete the files and the directories comprises the following steps:
step S1: and starting the recycle bin service of each node of the distributed file storage system.
And starting a recycle bin service of each node of the distributed file storage system by commanding the icfs-admin-recycle-start.
Step S2: adding an update parameter and a recycle _ time parameter in a recycle bin configuration file of a master node of a distributed file storage system, setting a parameter value of the update parameter and setting a value of the recycle _ time parameter as system time of the master node at a corresponding time point, wherein the parameter value of the update parameter is a time interval between two adjacent times of emptying of recycle bins, and the parameter value of the recycle _ time parameter represents recycle bin time of the master node when the recycle _ time parameter is added.
In the recycle _ conf configuration file (i.e. recycle bin configuration file) under the host node/usr/bin directory of the distributed file storage system, the update and recycle _ time parameters are newly added, and the system time system _ disk _ time of the host node is aligned with the recycle bin time recycle _ time of the recycle bin.
In this embodiment, update is 6000 ms.
Step S3: and synchronizing the recycle bin configuration file added with the update parameter and the recycle _ time parameter to other nodes of the distributed file storage system to align the recycle bin time.
In this embodiment, after synchronizing the recycle bin configuration file to which the update parameter and recycle _ time parameter are added to other nodes of the distributed file storage system for aligning the recycle bin time:

Step S4: and when the time interval corresponding to the parameter value of the update parameter is reached every time, emptying the files and the directories in the node recycle bin once respectively, unloading the emptied files and directories in the emptying process, recording the names and the emptying time of the emptied files, and recording the names and the emptying time of the emptied directories.
In this embodiment, according to a parameter value of an update parameter, files and directories in a recycle bin of each node of the distributed file storage system are completely deleted every 6000ms, and names of the files and directories that are emptied (i.e., deleted) in the recycle bin and an emptied time system _ disk _ time (the time is system time) are recorded, for example, when a file a and a directory B are deleted from the recycle bin in a node of the distributed file storage system, the name of the file a, the name of the directory B, the emptied time system _ disk _ time of the file a, the emptied time system _ disk _ time of the directory B, the name of the file a, the name of the directory B, the emptied time system _ disk _ time of the file a, and the emptied time system _ disk _ time of the directory B are recorded in the same SQ L database.
In this embodiment, the emptied files and directories in each node of the distributed file storage system are transferred to another SQ L database.
Step S5: and after receiving an instruction for recovering the target object, screening out the file name and the directory name with the same time of emptying from the recorded names of the emptied file and directory according to the time of emptying the target object from the recycle bin.
In this embodiment, the target object is a file a.
In this embodiment, the step S5 of screening out the file name and the directory name having the same time of being emptied from the recorded names of the emptied files and directories according to the time of the target object being emptied from the recycle bin includes the steps of:
reading the names and the emptying time of all emptied files and directories from the recycle bin of the distributed file storage system recorded in the SQ L database, and storing the names and the emptying time in a delete _ list;
the file name and directory name having the same cleared time as file a (target object) are screened out in the delete _ list.
For example, the system _ disk _ time when the file a is cleared is time 1, and the delete _ list is screened for the file name and the directory name that have the same cleared time as the file a, that is, the system _ disk _ time (cleared time) in the delete _ list is screened for the file name and the directory name that are the same as the time 1.
Other target objects may be referenced for execution. It should be noted that a plurality of target objects may be used, and the above embodiment may be specifically referred to.
Step S6: and screening out the files corresponding to the file names and the directories corresponding to the directory names from the dumped emptied files and directories, and recovering the files and the directories to the preset file system directories.
In this embodiment, in the step S6, in a specific implementation, a destination parameter is added to the recycle _ conf in advance, and according to the destination parameter value (which is a file system directory), the file corresponding to the file NAME (FI L E _ NAME) screened in the step S5 and the directory corresponding to the screened directory NAME (DIR _ NAME) are restored to the file system directory configured by the destination.
Step S7: and inquiring whether files and/or directories corresponding to the names of the target objects exist under the directory of the file system: if yes, the recovery is successful; if not, the recovery fails.
And inquiring whether files and directories of FI L E _ NAME and DIR _ NAME exist in the destination directory, if so, returning 0 (indicating that the recovery is successful) by the program, and otherwise, returning 1 (indicating that the recovery is failed) by the program.
It can be seen that the method can empty the files and directories in the recycle bin of the distributed file system once every time length set by the update parameter, thereby contributing to improving the operation performance of each node of the distributed file system, and can screen out the file names and directory names with the same empty time from the names of the recorded empty files and directories according to the time for the target object to be emptied from the recycle bin to carry out the restoration of the target object after receiving the instruction for restoring the target object.

and the recovery mechanism checking unit is used for checking whether the recycle bin configuration files of all the nodes of the distributed file storage system are configured with the update parameter and the recycle _ time parameter through commands after the synchronization unit synchronizes the recycle bin configuration files added with the update parameter and the recycle _ time parameter to other nodes of the distributed file storage system, outputting TRUE and continuing to execute the program if the checking result is yes, closing the recycle bin service of the distributed file storage system, outputting FA L SEE and terminating the program if the checking result is not.
8. The system for recovering the delete file and directory of the recycle bin as claimed in claim 7, further characterized in that the recovery mechanism checking unit adds a dynamic parameter in the recycle bin configuration file of the master node of the distributed file storage system in advance, wherein if the check result of checking whether the update parameter and the recycle _ time parameter are configured in the recycle bin configuration file of each node of the distributed file storage system by the command is yes, the dynamic FA L SE is determined if the check result of checking whether the update parameter and the recycle _ time parameter are configured in the recycle bin configuration file of each node of the distributed file storage system by the command is no.
9. The system for recovering a recycle bin deleted file and directory as claimed in claim 6, wherein the name and the time of emptying of each emptied file and the name and the time of emptying of each emptied directory are recorded in the same database.
10. The system for recovering the deleted files and directories in the recycle bin according to claim 9, further comprising a screening unit for screening out the file name and the directory name with the same emptying time from the recorded names of the emptied files and directories according to the emptying time of the target object from the recycle bin, wherein the specific implementation method comprises:
reading the names and the emptying time of each emptied file and directory recorded in the database, and storing the names and the emptying time in a delete _ list;
the file name and directory name that have the same cleared time as the target object are screened out in the delete _ list.
