Aiming at the problems of low processing efficiency, easy occurrence of false backup and missing backup when the data is manually re-backed up after the data backup errors in the related technology, a good solution method is not available in the related technology:
based on this, the present application intends to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.
According to an embodiment of the application, a data backup method is provided.
FIG. 1 is a flow chart of a data backup method according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S102, obtaining a backup log of initial data;
step S104, scanning the backup log to obtain first backup result information of the initial data, wherein the first backup result information comprises a first backup information mark;
step S106, based on the first backup result information, judging the backup result of the initial data;
step S108, when the backup result is that the backup fails, determining a first backup failure reason of the initial data and a first processing countermeasure corresponding to the first backup failure reason from a preset processing rule based on the first backup information mark;
step S110, based on the first processing countermeasure, the initial data is backed up again.
After the initial data is backed up, the first backup result information of the initial data can be obtained by scanning the backup log of the initial data, whether all the initial data is backed up successfully or not can be judged based on the first backup result information, and because the first backup result information is obtained by scanning the backup log of the initial data, the corresponding judged backup result can be detailed and comprehensive, for example, which data backup fails can be directly embodied in the backup result information, and in the case that the backup result is the backup failure, the reason of the backup failure of the initial data and the processing countermeasure corresponding to the reason can be determined from the preset processing rule based on the first backup information mark in the first backup result information, then the backup failure data in the initial data can be backed up again based on the processing countermeasure, after the data backup is in error, the backup error data can be directly backed up again according to the preset processing rule table, and each backup work is not required to be manually interfered, the backup processing efficiency is improved, the backup error and error problem of the data is solved when the backup error is easy to be carried out manually, and the error problem of the backup error is low is solved.
If the reason of the failure of the initial data backup and the processing countermeasure corresponding to the reason cannot be determined from the preset processing rule, the manual processing may be shifted to, for example, manually analyze whether the system can perform the re-backup processing by itself, and manually perform the re-backup if the system cannot perform the re-backup by itself.
It should be noted that, the foregoing preset processing rule may expand more backup failure reasons and corresponding processing countermeasures as the backup task proceeds.
Optionally, in the data backup method provided in the embodiment of the present application, the data type of the first backup result information is temporary data, where the first backup result information is cleared after the initial data is finished to be backed up again.
Since a plurality of backup tasks are performed simultaneously, if recording is performed using a regular file, naming of the file is complicated to avoid duplication, and a large number of intermediate files are generated, and cleaning process for these files is complicated after the backup tasks are finished.
In view of the foregoing, in this embodiment of the present application, a manner of making the data type of the first backup result information be temporary data is adopted, for example, log scan results (i.e., the first backup result information) are all set to be system temporary files, and the naming of the system temporary files is automatically generated by the system, so that naming efficiency is improved, and based on the naming of the files automatically generated by the system, the system temporary files can be used only for backup tasks, and after the backup tasks are finished, the system temporary files are automatically cleared without a complex clearing process.
Optionally, in the data backup method provided in the embodiment of the present application, the method for judging the backup result of the initial data may be multiple based on the first backup result information, for example, if the first backup result information further includes the first backup result return code, if the first backup result return code is a number returned when the preset backup fails, the backup result of the initial data is that the backup fails; or if the character at the preset character position in the first backup information mark is the corresponding character when the preset backup fails, the backup result of the initial data is the backup failure.
It should be noted that, the above-mentioned first backup result return code and the first backup information flag may be set according to the actual application requirement when the backup is successful or fails, for example, the first backup result return code may be set to 0 when the backup is completely successful without additional processing, and the first backup result return code may be set to any number (e.g., 8) greater than 0 when the backup is unsuccessful; the last character in the first backup information flag may be used to represent the backup result of the initial data, and different characters may be used to represent different backup conditions or error reasons, for example, character "I" represents that the backup is completed, character "W" represents that the backup is completed but has alarm information, character "E" represents that the backup is wrong, and so on.
It should be noted that, based on the method for judging the backup result, the integrity of the backup data can be improved by adopting a combination of two methods, so as to avoid missing the backup data, for example, after judging that the backup is completed according to the first backup result return code, the first backup information mark corresponding to each piece of data in the initial data can be continuously checked, and the initial data is judged to have completed the backup without error only when the first backup information mark corresponding to each piece of data indicates that the data is successfully backed up.
Optionally, in the data backup method provided in the embodiment of the present application, based on the first processing countermeasure, the re-backup of the initial data includes: determining target data needing to be backed up again in the initial data; writing the target data into the temporary file to obtain a target file; and re-backing up the initial data in a mode of backing up the target file. If the initial data has a backup error, all the initial data is not required to be backed up again, and only the data with failed backup is required to be backed up again, for example, the data corresponding to the first backup information mark containing characters representing the failure of backup or containing alarm information can be determined as target data, and the target data is backed up again.
It should be noted that, when the data volume of the re-backup is large, if the read data exceeds the limit, the direct reading of the target data may cause the error reporting of the backup task, so in the embodiment of the application, the data (i.e. the target data) to be re-backed up is written into the temporary file, and the re-backup is performed by reading the file, so as to avoid the error reporting of the backup task.
Optionally, the method further comprises: in the data backup method provided by the embodiment of the application, second backup result information of the target file is obtained, wherein the second backup result information comprises a second backup result return code and a second backup information mark; judging the backup result of the target file based on the second backup result information; determining a second backup failure reason of the target file and a second processing countermeasure corresponding to the second backup failure reason from a preset processing rule based on a second backup information mark under the condition that the backup result of the target file is that the backup fails; and re-backing up the target file based on the second processing countermeasure. After the re-backup is finished, in order to ensure the correct backup of the data, the backup condition of the target data can be checked again, and the method is similar to the processing of the initial data, the second backup result information can be obtained by obtaining the backup log of the target file, the backup result of the target file is judged according to the second backup result information, and the re-backup is carried out on the data which fails in backup again under the condition that the backup fails.
Optionally, in the data backup method provided in the embodiment of the present application, the method further includes: in the case where the operation of re-backing up the target file reaches a predetermined number of repetitions, the re-backing up for the target file is stopped. If the backup result is still the backup failure after the data which is failed in backup is backed up again for many times, the backup task is prevented from being trapped into long-time circulation by stopping the system to automatically re-backup and sending a method requiring manual intervention prompt in time, and the backup processing is performed manually, so that the complete backup of the data is ensured, and the timely completion of the backup of the data is ensured, so that the timeliness of the backup data is not influenced.
Based on the foregoing embodiment and the optional embodiments, an optional implementation manner is set forth in the present application, and is described below.
The IBM large-scale host data backup is an important link of daily backup of an information system, and is a safe and stable reliable foundation stone of the whole information system. The reasons for error in backup of host data are many, but most of them are due to redefinition of the data by deletion during the backup process. In the initial execution stage of the backup task, the task can read the corresponding relation between the data and the disk from the system and record the corresponding relation in the memory. Because the backup data volume is generally large, the backup tasks are time-consuming sequentially; meanwhile, the data backup is performed online and is completely transparent to the upper layer application. In the backup process, the data may be redefined after being deleted by the application program, so that the corresponding relationship between the data and the disk is changed. When the backup task performs backup, the corresponding relation stored in the memory in advance is read, and the data read from the disk fails to perform backup because the real corresponding relation is changed. The reason for this backup error covers the scenario of most backup errors. Of course, data backup is also subject to other reasons besides the most common backup error reasons, including artificial data name input errors, and the like.
The reasons for the backup errors are not the same, but generally are substantially the same for the post-error processing. In order to ensure the data integrity, the data which is not successfully backed up is backed up again. Based on the above facts, the alternative embodiment design of the present application develops an automatic processing method for data backup errors of an IBM mainframe, and fig. 2 is a flowchart of the automatic processing method for data backup errors of an IBM mainframe provided according to the alternative embodiment of the present application, and as shown in fig. 2, the method includes three modules of log reading, reason judging and re-backup, and the method effectively realizes the automatic processing function after the data backup errors. Meanwhile, in order to standardize the processing range of the backup error, the optional embodiment of the application sets a rule processing list. The list contains the information marks of backup errors which can be automatically processed and accumulated in long-term practice, and can be easily added and automatically matched by programs, so that the automatic backup range is continuously expanded.
The different modules in the method are described separately below.
(1) Module one: log reading module
Fig. 3 is a schematic diagram of a log reading module according to an alternative embodiment of the present application, where the module determines whether a data backup is successful by scanning a backup log. If the backup is completely successful, the backup task return code is automatically set to 0. If the backup task has any warning or error information, the backup task's return code will be greater than 0. According to the alternative embodiment of the application, the backup log is read and the situation of backup errors is analyzed aiming at the situation that the backup task return code is not 0.
Each record is successful or not in backup and generates a piece of information in the log. The information ends with a fixed character, "I" representing that the backup is complete; "W" represents that the backup is completed but there is alarm information; "E" represents a backup error. According to the rule, the completion of the backup is obtained preliminarily by scanning the log, and two types are roughly classified:
1) The backup is all successful while the module return code is set to 0. Since it is important to backup data, in order to avoid missing data, only if all the records of the data backup end with an "I", the backup is considered to be completely successful;
2) There is any backup record ending with "W" or "E", i.e., the backup is considered to fail. And the log result is scanned to obtain the data of the backup error and the corresponding backup error information, and meanwhile, the module return code is set to be 8.
Because the backup tasks are all performed simultaneously, if the conventional files are used for recording, the file naming is complex, a large number of intermediate files can be generated, and the subsequent cleaning is complex. In order to solve the problems, the log scanning results are set to be system temporary files by the log reading module, the system temporary file names are automatically generated by the system, the files can be ensured to be available only in the operation process of the backup task, the temporary files can be automatically cleared once the task is finished, and the temporary files can be shared and accessed by a plurality of modules in the whole operation process of the task.
(2) And a second module: reason judging module
Fig. 4 is a schematic diagram of a reason determining module according to an alternative embodiment of the present application, where the reason determining module mainly completes determining a log reading result, and forms a specific subsequent processing manner, so as to perform a next processing. According to the processing result of the log reading module, the optional embodiments of the present application respectively process:
1) If the module one return code is 0: the backup is completely successful, no additional processing is needed, the whole backup task return code is set to 0, the task is smoothly stopped, and no manual intervention is needed.
2) If the module one return code is 8: indicating that this backup was unsuccessful. In order to ensure that the data is backed up in the absence of errors, an automatic backup process is performed for the error conditions listed in the rule processing list. And according to the information marks corresponding to the data list with failed backup obtained by the log reading module, matching error information marks in the rule processing list one by one, and if each failed information mark belongs to the information mark of the rule processing list, considering that the backup task can automatically process the error backup data. If there is no perfect match, then human intervention is deemed necessary and the backup task return code is set to 13.
The rule processing list lists known scenarios for automatically processing backup errors. These scenarios are experience accumulation from long-term practice and can cover most error scenarios, and as mentioned above, the redefinition of data deletion is the main cause of error reporting of general data backup. After analysis and confirmation, the first data backup error can be automatically processed if the subsequent data backup error is considered to be automatically processed without manual intervention, and the first data backup error can be conveniently and continuously added into the rule processing list. The module automatically matches the rules in the list without excessive intervention.
For example, the error information mark included in the rule list may be ADR321E, ADR905E, ADR380E, etc., and if there is an information mark considered to be automatically processed, only the rule list needs to be added.
(3) And a third module: re-backup module
FIG. 5 is a schematic diagram of a re-backup module according to an alternative embodiment of the present application, although the reasons for the backup error are various, in order to ensure the integrity of the data, the processing manner after the error is to re-backup the data that is not successfully backed up. And the re-backup module performs first re-backup on the error file according to the result obtained by the reason judging module if the backup error can be automatically processed. If the first backup task is completely successful, the task return code is automatically set to 0, and the whole backup task is smoothly stopped without manual intervention.
When the data is re-backed up, if the data volume of the re-backup is larger, the direct reading can lead the read-in data to exceed the limit to cause the error reporting of the backup task. To solve this problem, alternative embodiments of the present application write the file that needs to be reprocessed into a temporary file, and the backup task avoids this problem by reading the temporary file.
And if the backup task return code of the first re-backup is not 0, performing the automatic processing again according to the processing principle. If the backup task of the second backup is still unsuccessful, the optional embodiment of the present application generally sets the entire backup task to return to 11, and the entire backup task is suspended, which indicates that manual intervention is required. The third and fourth re-backup can be performed, and the setting is generally performed according to the actual application requirement.
In summary, the optional implementation manner of the application provides an automatic processing method for backup errors under backup of IBM large-scale host files, which can automatically judge and automatically process various scenes after the backup errors, does not need manual intervention, and greatly improves backup efficiency and backup accuracy.
According to the data backup method, the backup log of the initial data is obtained; scanning the backup log to obtain first backup result information of the initial data, wherein the first backup result information comprises a first backup information mark; judging the backup result of the initial data based on the first backup result information; under the condition that the backup result is that the backup fails, determining a first backup failure reason of the initial data and a first processing countermeasure corresponding to the first backup failure reason from a preset processing rule based on a first backup information mark; based on the first processing countermeasure, the initial data is re-backed up. The method solves the problems of low processing efficiency, easy error backup and missing backup when the data is manually re-backed up after the data backup is in error in the related technology. After the data backup is in error, the data in error can be automatically and re-backed up directly according to the preset processing rule table, each backup work is not needed to be manually interfered, the backup processing efficiency is improved, and the effects of error backup and missing backup are avoided.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.
