Fig. 1 is a flow chart of a disaster recovery method for a data center according to an embodiment of the present application.
As shown in fig. 1, the main flow of the method is described as follows (steps S101 to S103):
step S101, target transmission data information of target transmission data is obtained in response to a disaster recovery instruction sent by a data center to be transmitted.
In this embodiment, the target transmission data information includes a data security level, a data size, and a data type, where the security level is a level of data to be protected, and is associated with a data content of the target transmission data, and is determined according to a data source of the target transmission data, or is manually set by a staff, and the data size is a content size occupied by the data, such as bit, KB, GB and TB, and the data type is a specific type of data, such as video may be classified into a smiling video, a teaching video, a dance video, and the like, and when the data type is displayed, whether the video is a smiling video, a teaching video, a dance video, or the like needs to be displayed, where the data type is a distance specification, and the specific data type needs to be set according to the current target transmission data, which is not particularly limited herein.
Step S102, a target disaster recovery data center is selected based on the target transmission data information.
Aiming at step S102, a storage block of a disaster recovery data center and storage block information of the storage block are obtained; calculating the matching degree of the storage block information and the target transmission data information; sorting the storage blocks based on the magnitude of the value of the matching degree to generate a first matching degree sequence; and selecting a disaster recovery data center based on the first matching degree sequence, and taking the selected disaster recovery data center as a target disaster recovery data center.
When the target disaster recovery data center is selected, a disaster recovery center is not selected randomly and is used as the target disaster recovery data center, and the selection is required according to storage block information and target transmission data information in the disaster recovery data center, wherein the storage block information comprises a storage security level, an idle capacity value and a storage type; generating a first degree of matching based on the storage security level and the data security level; generating a second degree of matching based on the free capacity value and the data size; generating a third matching degree based on the storage type and the data type; and calculating the matching degree of the storage block information and the target transmission data information based on the first matching degree, the second matching degree, the third matching degree and a preset calculation rule.
In this embodiment, the matching degree is calculated from three aspects respectively, the first matching degree is calculated according to the data security level in the target transmission data information and the storage security level in the storage block information, the second matching degree is calculated according to the data size in the target transmission data information and the free capacity value in the storage block information, and the third matching degree is calculated according to the data type in the target transmission data information and the storage type in the storage block information.
In the first aspect, judging whether the data security level is the same as the storage security level, and if the data security level is the same as the storage security level, the first matching degree is the highest value; if the data security level is different from the storage security level, the absolute value of the difference between the storage security level and the data security level is calculated no matter whether the storage security level is higher than the data security level or lower than the data security level, each absolute value of the difference corresponds to one matching degree, and the corresponding matching degree is selected as the first matching degree according to the calculation result.
In the second aspect, judging whether the idle capacity value is not smaller than the data size, and if the idle capacity value is not smaller than the data size, the second matching degree is the highest value; and if the idle capacity value is smaller than the data size, the second matching degree is the lowest value.
In a third aspect, a storage type name of a storage type and a target type name of a data type are acquired; judging whether the storage type name is the same as the target type name; if the storage type name is the same as the target type name, acquiring a storage type level and a target type level; when the storage type level is the same as the target type level, setting the third matching degree to be the highest value; when the storage type level is different from the target type level, acquiring a minimum level containing the storage type level and the target type level, and taking a matching value corresponding to the minimum level as a third matching degree; and if the storage type name is not the same as the target type name, setting the third matching degree to be the lowest value.
In this embodiment, when calculating the matching degree of the storage type and the data type, it is first determined whether the storage type name corresponding to the storage type is consistent with the target type name corresponding to the data type, and when the storage type name is inconsistent with the target type name, it is indicated that no link exists between the storage type name and the target type name, and data disaster recovery cannot be performed, so that the third matching degree is set to the minimum value. When the storage type name is consistent with the target type name, further calculation of the specific matching degree of the storage type and the data type is needed, the storage type name and the target type name are in a level form, each level comprises at least one small level smaller than the current level, each level and each small level are corresponding to one matching degree, and when the storage type level and the target type level are the same, the matching degree is the highest value. When the storage type level and the target type level are different, a minimum level which can simultaneously contain the storage type level and the target type level needs to be searched forward, and a matching value corresponding to the minimum level is used as the matching degree of the storage type and the data type.
For example, when the storage type name and the target type name are the same, the storage type name is a 00A type, wherein the storage type name is a and B, the a contains A1 and A2, the storage type name is further divided into A1, a11, a111, a12, a121, a122, a13, a131, a132 and a133, wherein the matching value of a and B is twenty percent, the matching value of A1 and A2 is fifty percent, the matching value of a11, a12 and a13 is eighty percent, the matching value of a111, a121, a122, a131, a132 and a133 is hundred percent, when the storage type level and the target type level are both a111, the matching value of the storage type level and the target type is hundred percent, and when the storage type level is a121 and the target type a131, the minimum same level is A1 needs to be searched for, and the matching value corresponding to A1 is fifty percent. It should be noted that, the specific level division manner needs to be set by division according to the above-mentioned actual type setting manner, and the matching value needs to be set according to the specific level division number, which is not limited herein.
And respectively obtaining a first matching value, a second matching value and a third matching value according to the first matching degree and the first matching ratio, the second matching degree and the second matching ratio, and the third matching degree and the third matching ratio, adding the first matching value, the second matching value and the third matching value to obtain the matching degree of the storage block information and the target transmission data information, and sequencing the storage blocks according to the numerical value of the matching degree to generate a first matching degree sequence.
In this embodiment, when the disaster recovery data center is selected based on the first matching degree sequence, whether the matching degrees are smaller than a preset matching threshold value is judged; if the matching degrees are smaller than the preset matching threshold, selecting storage blocks with corresponding idle capacity values larger than the data size according to the preset selection number; taking a disaster recovery data center corresponding to a storage block with an idle capacity value larger than the data size as a target disaster recovery data center; if the matching degrees are not smaller than the preset matching threshold, arranging the storage blocks with the matching degrees not smaller than the preset matching threshold according to the matching degree, and generating a second matching degree sequence; and selecting the disaster recovery data center based on the second matching degree sequence and a preset selection rule. The preset matching degree threshold needs to be set according to actual requirements, and the preset matching degree threshold transmitted each time may be the same or different, and is not limited in detail herein.
When the matching degree of all the storage blocks in the first matching degree sequence is smaller than a preset matching threshold value, the storage capacity of the data is used as a first factor, the disaster recovery data center corresponding to the storage block capable of storing the target transmission data is selected as a target disaster recovery data center, firstly, after the disaster recovery data centers corresponding to the storage blocks with the idle capacity value larger than the data size are selected, the disaster recovery data centers corresponding to at least one storage block in the sequence are sequentially selected from large to small and are still arranged according to the descending order of the matching degree, the specific selection quantity is required to be set according to actual requirements, and the specific selection quantity is not limited.
When the disaster recovery data center is selected based on the second matching degree sequence and a preset selection rule, if the storage blocks in the second matching degree sequence belong to the same disaster recovery data center, the disaster recovery data center is used as a target disaster recovery data center; if the storage blocks in the second matching degree sequence do not belong to the same disaster recovery data center, counting the number of the storage blocks with the highest matching degree in the second matching degree sequence and the first storage blocks belonging to the same disaster recovery data center; generating a first duty ratio based on the counted first storage block number and the storage block number in the second matching degree sequence; if the first duty ratio is not smaller than the preset duty ratio threshold, taking the disaster recovery data center of the storage block with the highest matching degree as a target disaster recovery data center; if the first duty ratio is smaller than a preset duty ratio threshold, respectively counting the number of second storage blocks positioned in the second matching degree sequence, which are included in each disaster recovery data center to which other storage blocks in the second matching degree sequence belong; and taking the disaster recovery data center with the most second storage blocks as the target disaster recovery data center, wherein the disaster recovery data center with the most second storage blocks belongs to the storage blocks with the highest matching degree.
In this embodiment, the storage blocks in the second matching degree sequence are all storage blocks with matching degrees higher than a preset matching degree threshold, so as to improve the convenience of the transmission of the target transmission data, reduce the processing pressure of the computer, ensure that the target transmission data can be successfully subjected to disaster recovery backup, and reduce the number of the target disaster recovery data centers as much as possible when the disaster recovery data centers are selected, and if all the storage blocks in the second matching degree sequence belong to the same disaster recovery data center, the disaster recovery data center can be directly selected as the target disaster recovery data center.
Because the storage block with the highest matching degree is the optimal choice of the data disaster tolerance, if the storage blocks in the second matching degree sequence do not belong to the same disaster tolerance data center, the number of the storage blocks, namely the number of the first storage blocks, of the second matching sequence, which belong to the same disaster tolerance data center as the highest storage block, needs to be further counted, and the ratio of the number of the first storage blocks to the number of all the storage blocks in the second matching sequence is calculated to generate a first duty ratio. And if the first duty ratio is greater than or equal to a preset duty ratio threshold, taking the disaster recovery data center of the storage block with the highest matching degree as a target disaster recovery data center, and if the first duty ratio is smaller than the preset threshold, respectively counting the number of second storage blocks positioned in the second matching degree sequence and included in each disaster recovery data center of the storage blocks except the storage block with the highest matching degree in the second matching degree sequence, and taking the disaster recovery data center with the highest number of counted second storage blocks and the disaster recovery data center with the highest matching degree as the target disaster recovery data center.
For example, the second matching degree sequence includes A, B, C, D, E, F six storage blocks, where the storage block a is the storage block with the highest matching degree, the matching degree of the remaining five storage blocks gradually decreases along with the sorting position, if A, B, C, D, E, F the six storage blocks belong to one disaster recovery data center, the disaster recovery data center is directly taken as a target disaster recovery data center, if A, B, C, D, E, F the six storage blocks do not belong to one disaster recovery data center, and if the preset duty ratio threshold is 50%, the number of first storage blocks belonging to one disaster recovery data center with the storage block a needs to be counted, if both the storage block B and the storage block C belong to one disaster recovery data center with the storage block a, the number of the first storage blocks is 3, the first duty ratio is calculated to be 50%, the first duty ratio is the same as the preset duty ratio threshold, and the disaster recovery data centers corresponding to the storage block a, the storage block B and the storage block C are taken as the target disaster recovery data centers; if the storage block B and the storage block A belong to the same disaster recovery data center, the storage block C, the storage block D and the storage block E belong to the same disaster recovery data center, the storage block F belongs to one disaster recovery data center, the number of the first storage blocks is known to be 2, the number of the second storage blocks is known to be 3, the calculated first duty ratio is 33%, and the first duty ratio is smaller than a preset duty ratio threshold value, then the disaster recovery data centers corresponding to the storage block A and the storage block B and the disaster recovery data centers corresponding to the storage block C, the storage block D and the storage block E are used as target disaster recovery data centers. The preset duty ratio needs to be set according to the data size of the actual disaster recovery data center, which is not specifically limited herein.
Step S103, transmitting the target transmission data to the target disaster recovery data center based on the current transmission environment.
In this embodiment, a target data transmission environment is calculated based on a data size and an expected required transmission time length; judging whether the transmission environment accords with the target data transmission environment or not; if the transmission environment accords with the target data transmission environment, transmitting target transmission data to a target disaster recovery data center; if the transmission environment does not accord with the target data transmission environment, storing the target transmission data into a preset local backup space; and when the transmission environment accords with the target transmission environment, transmitting target transmission data in the preset local backup space to a target disaster recovery data center.
Calculating a target transmission rate, namely a target transmission environment according to the data size and the expected demand transmission time length, acquiring the current transmission rate, transmitting target transmission data to a target disaster recovery data center when the current transmission rate is greater than or equal to the target transmission rate, otherwise, arranging the target transmission data which are input into the preset local backup space according to the adding time when the target transmission data are added into the preset local backup space, adding a to-be-transmitted identifier for each target transmission data which are input into the preset local backup space and the source position of the target transmission data in a queue, and deleting the to-be-transmitted identifier when the current transmission rate is greater than or equal to the target transmission rate and the target transmission data are successfully sent out.
In this embodiment, transmission additional information is acquired, and a transmission report is generated based on the transmission additional information; a transmission file is generated based on the transmission report.
Further, the generation time of the transmission report and the report type are obtained; and sequentially arranging the transmission report sheets with the same report sheet type according to the generation time to generate a transmission file.

And then arranging report sheets with the same report sheet type according to the generation time sequence to generate a transmission file, so that a worker can know the data transmission condition in a period of time according to the transmission file.
