Based on the hardware structure, the embodiment of the method for determining the recovery time of the backup data is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for determining backup data recovery time according to a first embodiment of the present invention.
In a first embodiment, the backup data recovery time determination method includes the steps of:
s10: and when a recovery time determining instruction is received, extracting the backup data to be recovered and the current recovery mode from the recovery time determining instruction.
It should be noted that, the user may trigger the recovery time determination instruction through a key on the keyboard, may trigger the recovery time determination instruction through a mouse, and may trigger the recovery time determination instruction through a touch screen, which is not limited in this embodiment.
It can be understood that, as for the recovery time determining instruction, it can be understood that the instruction is an instruction for acquiring time required by the backup data to be recovered when the backup data to be recovered is recovered through the current recovery mode, and therefore, as for the recovery time determining instruction, the backup data to be recovered and the current recovery mode are carried, and therefore, the backup data to be recovered and the current recovery mode can be extracted from the recovery time determining instruction.
S20: and determining a corresponding backup task to be restored according to the backup data to be restored.
In a specific implementation, the backup data to be restored may be understood as a certain backup point of the backup source device, and for the backup source device, it usually has a continuous backup process, such as: the backup mode of the backup source device is one backup for each hour, and if the backup start time is set to be 9 am at 5/3/2020, then normally, one backup needs to be performed every hour, and the continuous backup process needs to be implemented by one backup task, so that one backup task corresponds to one backup source device, and one backup task generates a plurality of backup data, so that after the backup data to be restored is determined, the corresponding backup task to be restored can be determined according to the backup data to be restored.
S30: and determining corresponding target recovery time according to the backup task to be recovered and the current recovery mode.
It should be noted that, after determining the backup task to be restored and the current restoration mode, the corresponding target restoration time may be determined, and therefore, in this embodiment, the corresponding target restoration time may be determined according to the backup task to be restored and the current restoration mode.
In this embodiment, when a recovery time determination instruction is received, the to-be-recovered backup data and the current recovery mode are extracted from the recovery time determination instruction, then a corresponding to-be-recovered backup task is determined according to the to-be-recovered backup data, and finally a corresponding target recovery time is determined according to the to-be-recovered backup task and the current recovery mode.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for determining a recovery time of backup data according to a second embodiment of the present invention, and the method for determining a recovery time of backup data according to the second embodiment of the present invention is proposed based on the embodiment illustrated in fig. 2.
In the second embodiment, step S30 specifically includes:
s31: and searching for target recovery time corresponding to the backup task to be recovered and the current recovery mode in a preset mapping relation, wherein the preset mapping relation comprises the corresponding relation among the backup tasks, the recovery modes and the recovery time.
It should be noted that, in order to improve the efficiency of obtaining the target recovery time, in this embodiment, a preset mapping relationship may be established in advance, where the preset mapping relationship includes a corresponding relationship between each backup task, the recovery mode, and the recovery time, and when the target recovery time needs to be determined, the target recovery time corresponding to the backup task to be recovered and the current recovery mode may be searched in the preset mapping relationship.
It is understood that the recovery modes can be generally classified into volume mount recovery, file recovery, virtual machine takeover recovery, Small Computer System Interface (ISCSI) recovery, and full scene recovery, and thus the current recovery modes are usually volume mount recovery, file recovery, virtual machine takeover recovery, ISCSI recovery, or full scene recovery.

In the third embodiment, before step S10, the method further includes:
s01: and performing recovery drilling on a plurality of historical backup data corresponding to each backup task according to different recovery modes respectively to obtain a recovery drilling result.
It can be understood that, when the current recovery mode is volume mount recovery, the corresponding recovery drilling mode is to mount data backed up in a volume backup mode in backup data to a host for drilling, and determine the corresponding recovery time;
when the current recovery mode is file recovery, the corresponding recovery drilling mode is to recover a single file in the backup data to the original application system and data to perform simulated disaster drilling and determine the corresponding recovery time;
when the current recovery mode is virtual machine recovery, the corresponding recovery drilling mode is to start the backup data in a virtual machine mode for drilling, and determine the corresponding recovery time;
when the current recovery mode is the small computer system interface ISCSI recovery, the corresponding recovery drilling mode is to drill the backup data in an ISCSI mounting mode and determine the corresponding recovery time;
when the current recovery mode is full-scene recovery, the corresponding recovery drilling mode is drilling by using backup data and adopting a full-scene recovery mode, the operation system, the application system, the database, the data and the like are recovered and set up, and the corresponding recovery time is determined.
S02: and generating a preset mapping relation according to the recovery drilling result.
In a specific implementation, the recovering the drilling result includes: and the plurality of historical backup data corresponding to each backup task are respectively subjected to recovery time lengths corresponding to recovery drilling according to different recovery modes.
In order to quickly generate the preset mapping relationship, in this embodiment, the recovery durations corresponding to the same backup task and the same recovery mode may be counted from the recovery drilling result; calculating the average value of the recovery time lengths corresponding to the same backup task and the same recovery mode, and taking the calculated average value as the recovery time corresponding to the same backup task and the same recovery mode; and generating a preset mapping relation according to the recovery time corresponding to the same backup task and the same recovery mode.
For example: a backup task a corresponds to 5 pieces of historical backup data, at this time, it is assumed that recovery drilling is performed on the 5 pieces of historical backup data according to a volume mount recovery mode, and recovery time durations are respectively 10min, 11min, 12min, 10min and 12min, at this time, since the 5 pieces of recovery time durations correspond to the same backup task (i.e., backup task a) and the same recovery mode (i.e., volume mount recovery), an average value 11min of the 5 pieces of recovery time durations can be calculated, and the calculated average value 11min can be used as recovery time for volume mount recovery of the backup task a;
certainly, it is assumed that the 5 pieces of historical backup data are subjected to recovery drilling in a full-scene recovery mode, and the obtained recovery time durations are 21min, 30min, 25min, 24min and 20min, at this time, since the 5 recovery time durations correspond to the same recovery mode (i.e., full-scene recovery) of the same backup task (i.e., backup task a), an average value 11min of the 5 recovery time durations can be calculated, and the calculated average value 11min can be used as the recovery time of the full-scene recovery of the backup task a.
Referring to fig. 5, fig. 5 is a flowchart illustrating a method for determining a recovery time of backup data according to a fourth embodiment of the present invention, and the fourth embodiment of the method for determining a recovery time of backup data according to the present invention is proposed based on the embodiment shown in fig. 3.
In the fourth embodiment, before step S01, the method further includes:
s001: respectively carrying out file consistency verification on a plurality of historical backup data corresponding to each backup task to obtain a file consistency verification result; and when the file consistency result is that the verification is passed, executing the step of performing recovery drilling on the plurality of historical backup data corresponding to each backup task according to different recovery modes respectively to obtain a recovery drilling result.
It should be noted that, since the backup task may have formed a plurality of corresponding historical backup data, but the historical backup data may cause inconsistency between the historical backup data and the data in the backup source device due to problems such as network reasons or data transmission reasons, in order to ensure the security of the data, in this embodiment, before step S01, a file consistency verification may be performed.
In a specific implementation, in order to ensure the validity of the file consistency verification, in this embodiment, the file consistency verification may be performed with the backup source device when the historical backup data is generated.
It can be understood that the file consistency verification can be realized by a file browsing and comparing manner, that is, files in the historical backup data can be browsed, and the browsed files are compared with files of the backup source device, so that the file consistency verification is realized.

s003: respectively performing system application verification on a plurality of historical backup data corresponding to each backup task to obtain a system application verification result; and when the system application verification result is that the verification is passed, executing the step of performing recovery drilling on the plurality of historical backup data corresponding to each backup task according to different recovery modes respectively to obtain a recovery drilling result.
It should be noted that, since the backup task may have formed a plurality of corresponding historical backup data, but the corresponding systems and applications in the historical backup data may not be normally used, in order to ensure that the systems and applications in the historical backup data can be normally used, in this embodiment, before step S01, system application verification may be performed.
In a specific implementation, the system application verification may be performed by determining whether the system can be started, whether a service/process related to the system can be started, whether an application can be started, whether the application can be normally used, and the like.
