Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide an optimization method, a device, equipment and a medium for data recovery. Whether the current recovery period is the recovery period of the target file or not can be judged; therefore, the adopted control parameters are determined according to the two conditions of the recovery period of the target file and the recovery periods of other file data, so as to control different recovery speeds; on the premise of ensuring that the working performance of the front end is not affected, the recovery efficiency of the target file and the speed of the whole recovery process are improved, and the requirements of users are better met.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a flowchart of an optimization method for data recovery according to an embodiment of the present invention; as shown in fig. 1, an optimization method for data recovery according to an embodiment of the present invention includes steps S101 to S105:
step S101: setting a target control parameter for controlling the recovery speed of the target file; the target file is a file with a data volume smaller than the specified data volume;
it can be understood that the control parameters are used to control the recovery speed of the file, and different control parameters are used for regulation, which will result in different recovery speeds, i.e. the maximum data amount and the maximum number of objects that can be recovered in one recovery period are different. In one embodiment, a target control parameter for controlling the restoration speed of the target file is set in advance. Specifically, the target control parameter may maximize the recovery speed of the target file in the current application environment without affecting the working performance of the front end. It is understood that the target control parameter is a control parameter corresponding to the maximum restoration speed of the target file. It should be noted that, a person skilled in the art may set the target control parameter according to an actual application situation, and the embodiment of the present invention is not limited.
Step S102: acquiring a preset condition meeting the target period requirement; the target period is specifically a recovery period for recovering the target file;
step S103: judging whether the current recovery period meets the condition; if yes, go to step S104; if not, the step S105 is entered;
step S104: adjusting the current control parameter to a target control parameter to recover the target file;
step S105: and adjusting the current control parameters to the appointed control parameters preset by the user.
In specific implementation, a preset condition meeting the requirement of a target period is obtained; judging whether the current recovery period meets the condition; that is, whether the current recovery period is the recovery period of the target file is judged, if yes, the control parameter can be adjusted to the target control parameter to recover the target file under the target file recovery scene. By adjusting the control parameters to the target control parameters, the maximum number of objects which can be recovered in each recovery period is increased, and the number of objects recovered in each data recovery operation is increased. If not, the file is currently in other file recovery scenes. And when the priority is set by the user, the control is continued according to the preset designated control parameters so as to ensure the working performance of the front end.
In the target file recovery scenario, the target file is to be continuously recovered for a certain period of time. During the data recovery process, each recovery scenario lasts for a period of time, and each recovery period is short in duration, usually set to several seconds. The duration of one recovery scenario takes multiple recovery periods. For example, the recovery period is 2s, the current recovery scenario is 30s, and the next recovery scenario is entered after all data in the current recovery scenario is recovered.
Specifically, since each recovery scenario continues for multiple recovery cycles, for example, in the target file recovery scenario, multiple consecutive recovery cycles are used to recover the data of the target file. Therefore, whether the current recovery period is the recovery period of the target file or not can be judged through the history recovery period adjacent to the current recovery period. If the data recovered by the historical recovery period is the target file, the historical recovery period is in the target file recovery scene, and the current recovery period adjacent to the historical recovery period can be judged to be the target file recovery scene, and the current recovery period is the target file recovery period. It can be understood that, when the recovery scene lasts for a longer time, the shorter the recovery period is set, the more accurate the determination result is.
In one embodiment, the condition is that the ratio of the target files of the historical recovery period adjacent to the current recovery period is greater than a preset ratio; the target file proportion is the ratio of the number of the target files in the historical recovery period to the total number of the objects;
the specific steps of judging whether the current recovery period meets the conditions provided by the invention include:
acquiring a target file ratio;
judging whether the target file proportion is larger than a preset proportion or not;
if yes, the current recovery period is in accordance with the condition.
In specific implementation, whether the current recovery period is the recovery period of the target file is determined by judging whether the current recovery period meets the condition. When judging whether the current recovery period meets the condition, firstly, the target file proportion of the historical recovery period is obtained, namely the ratio of the number of the target files to the total number of the objects in the historical recovery period. And when the obtained target file proportion is larger than the preset proportion, determining that the historical recovery period is the recovery period of the target file. Therefore, the current recovery period is determined to be the recovery period of the target file. It should be noted that, the preset ratio can be determined by various ways according to the actual application situation by those skilled in the art.
In one embodiment, the obtaining the target file ratio specifically includes:
in a historical recovery period, judging whether the data value of each recovery object is smaller than a preset target data value or not;
if so, determining that the recovery object is a target file;
the number of target files is counted and the ratio of the number to the total number of objects restored is calculated.
Specifically, the target file proportion is equal to the ratio of the number of target files in the history recovery period to the total number of objects. Therefore, the number of target files in the history recovery period and the total number of objects are respectively obtained, and the target file ratio can be calculated. When the number of the target files is obtained, each recovery object can be judged according to the target data value, whether the data volume of the recovery object is smaller than the target data value or not is judged, and if yes, the recovery object is determined to be the target file. It will be appreciated that the data size of the target file may be less than the data size of the storage object having the default size into which the file having the large data size is split. In one embodiment, the target data value may be set to the data amount of the storage object of the default size, and when the data amount of the restoration object is smaller than the data amount of the storage object of the default size, the restoration object is determined to be the target file. It should be noted that, those skilled in the art can determine the target data value according to the actual application.
In the specific implementation, counting is carried out in the process of each recovery period, and when the current recovery object is determined to be the target file, the number of the target files is increased by one; each time an object is restored, one is added to the total number of objects. And after the recovery period is finished, counting the number of the target files recovered in the recovery period and the total number of the recovered objects.
The invention provides an optimization method for data recovery, which comprises the following steps of firstly, setting a target control parameter for controlling the recovery speed of a target file; the target file is a file with a data volume smaller than the specified data volume. And according to the acquired condition meeting the target period requirement; judging whether the current recovery period meets the condition; therefore, the current control parameters are determined aiming at the target period and other recovery periods so as to control different recovery speeds; if the target period is the target period, adjusting the current control parameter to be the target control parameter so as to improve the recovery speed of the target file; if the file is recovered in other recovery periods, the current control parameters are adjusted to the appointed control parameters preset by the user, and the file is recovered continuously at the appointed recovery speed. Therefore, in the recovery process, if the current recovery period is the target period, the current control parameter is adjusted to enable the current control parameter to have the recovery speed adaptive to the target file; if in other recovery periods, the control is carried out according to the appointed control parameters of the user, so that the recovery efficiency of the target file and the speed of the whole recovery process are improved on the premise of ensuring that the working performance of the front end is not influenced, a large amount of working time is saved, and the requirements of the user can be better met.

step S201: and generating a log for recording each recovery object of the historical recovery period, the number of target files and the total number of the objects.
By generating logs of the recovery objects, the number of target files and the total number of the objects in the historical recovery period, subsequent workers can check and check conveniently, analysis is carried out according to the recorded content, and all parameters in the subsequent recovery process can be adjusted in time.
As shown in fig. 2, the method for optimizing data recovery according to the embodiment of the present invention further includes:
step S202: and updating the preset proportion and the target data value according to the content recorded in the log.
Specifically, according to information such as the number of recovery objects, target files and the total number of objects in a historical recovery period, whether a preset proportion and a target data value adopted at present need to be updated or not is analyzed, so that the efficiency of the whole recovery process is improved better on the premise of not influencing the working performance of a front end; if the data needs to be recovered, the preset proportion and the target data value are updated, so that the data can be better adapted to the current application environment, the recovery efficiency is improved to the maximum extent, and the requirements of users are met.
As shown in fig. 2, the method for optimizing data recovery according to the embodiment of the present invention further includes:
step S203: judging whether an abnormal condition exists according to the content recorded in the log; if yes, go to step S204;
step S204: a warning prompt is made in the log.
In the recovery process, judging whether an abnormal condition exists according to the content recorded in the log; when the recovery process is found to be abnormal, warning prompt can be carried out in the log, so that workers can find the abnormal problem in time conveniently, the abnormal problem can be found and solved quickly by analyzing the content recorded by the log, and the recovery speed in the whole process is improved.
Specifically, the contact information may be based on a pre-stored contact information of the staff, such as a mailbox or a telephone number. When the recovery process is abnormal, the abnormal information can be notified to the staff according to the contact way, so that the staff can timely process the abnormal information. The whole recovery process is more efficient, the worker is not required to check all the time, and convenience is brought to work.
In one embodiment, the method for optimizing data recovery further includes:
after the target control parameter is set, judging whether the target recovery speed corresponding to the target control parameter is smaller than the designated recovery speed corresponding to the designated control parameter;
If so, keeping the current control parameter as the designated control parameter.
It is understood that the current control parameter is a specific control parameter preset by a user, so as to achieve the recovery speed of the data to reach the specific recovery speed. After the target control parameters are set, whether the target recovery speed corresponding to the target control parameters is smaller than the specified recovery speed corresponding to the specified control parameters or not can be judged firstly, if yes, the current recovery speed is higher, the data recovery efficiency is higher, the recovery can be continued according to the current recovery speed, the subsequent judgment of whether the recovery period is the target file or not is not needed, the flexibility of data recovery is improved, and the requirements of users are met better.
The invention also provides an embodiment corresponding to the data recovery optimizing device, and the data recovery optimizing device is explained based on the angle of the functional module.
