Background
Backup is a disaster-tolerant basis, and refers to a process of copying all or part of a data set from a hard disk or an array of an application host to another storage medium in order to prevent data loss caused by misoperation of a system or system failure. The traditional data backup mainly adopts a built-in or external tape unit for cold backup. However, this method can only prevent human failures such as misoperation, and the recovery time is long. With the continuous development of the technology, the amount of data is increased, and a large number of enterprises begin to adopt network backup. Network backups are typically implemented by specialized data storage management software in conjunction with corresponding hardware and storage devices.
The power data is sensitive and important data of the country, and the production and activity conditions of the whole country and local regions can be intuitively reflected through the power data. In order to enable stable storage of power data, effective encryption backup of the power data based on a network is required, and when the backup power data needs to be restored, effective verification is required to prevent others from stealing the backup power data. After verification, the backed-up data is sent to the requesting end that requests the data, but the data transmission is slow due to the large amount of data.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The invention provides a multi-zone information backup verification recovery method suitable for a middlebox, which is applicable to a scene shown in figure 1 and comprises a first backup terminal arranged in a first zone, a second backup terminal arranged in a second zone and a recovery request end arranged in a third zone, wherein the first backup terminal and the second backup terminal respectively store the same backup data.
In an actual data backup and storage scenario, at least two different areas are generally set to backup and store the same information and data. When the backup recovery is needed, the recovery request end sends a verification recovery request and the backup receiving end information to the middle station. The backup receiving end may be the same terminal as the restoration requesting end, or the backup receiving end may not be the same terminal as the restoration requesting end. The backup receiving end may be in the third area or the fourth area, and the present invention is not limited thereto.
The recovery request terminal may be a terminal with an identity acquisition function. The first backup terminal, the second backup terminal and the recovery request terminal can be mobile terminals such as a database, a server and a mobile phone.
The inventor needs to say that, the data sending speed and the data receiving speed of a data end with transceiving function are not the same, that is, the uplink rate and the downlink rate of a data end are different. Generally, the uplink rate and the downlink rate of the data end are normal at a ratio of 1:7 or more, so it can be understood that if the configurations of the first backup terminal, the second backup terminal and the backup receiving end are the same, the backup receiving end can simultaneously receive information and data sent by a plurality of first backup terminals and second backup terminals. Therefore, when the backup receiving terminal in a certain area needs to restore the backed-up information and data, the information and the data are simultaneously sent to the backup receiving terminal through the first backup terminal and the second backup terminal in other areas.
The recovery request end can only collect the identity information and appoint the backup receiving end, and the recovery request end has special purpose by the way, namely when the backup information and data need to be recovered, the corresponding verification recovery request and the backup receiving end information can be sent by the recovery request end. The backup receiving end information is a backup receiving end for specifying the receiving information and the data.
As shown in fig. 2, the middle station performs backup verification recovery by the following steps:
step S110, receiving a verification recovery request and backup receiving end information sent by a recovery request end, and if the verification recovery request passes, determining a backup address of the backup receiving end information, a first address of a first backup terminal and a second address of a second backup terminal.
In the technical solution provided by the present invention, step S110 specifically includes:
and comparing the verification information in the verification recovery request with the preset information, and if the verification information is consistent with the preset information, the verification recovery request passes. The authentication information in the present invention may be current fingerprint information, current login account-password information, current face information, and the like. The preset information may be preset fingerprint information, preset login account-password information, and preset face information.
And determining the backup address of the backup receiving terminal information, the first address of the first backup terminal and the second address of the second backup terminal. The backup address, the first address, and the second address may be IP addresses.
If the current fingerprint information is consistent with the preset fingerprint information, the current login account-password information is consistent with the preset login account-password information, or the current face information is consistent with any one of the preset face information, the verification information is compared with the preset information to be consistent, and the verification recovery request passes.
Step S120, a first transmission channel is established between the backup address and the first address, a second transmission channel is established between the backup address and the second address, a first uplink rate of the first backup terminal in the first transmission channel is obtained, and a second uplink rate of the second backup terminal in the second transmission channel is obtained.
The invention can obtain the first IP address of the first address, the second IP address of the second address and the backup IP address of the backup address. And a first transmission channel is established according to the first IP address and the backup IP address, a second transmission channel is established according to the second IP address and the backup IP address, and backup information and data which are pre-stored in the first backup terminal and the second backup terminal are sent and transmitted through the first transmission channel and the second transmission channel. The first uplink rate and the second uplink rate are transmission rates of information and data sent by the first backup terminal and the second backup terminal to the backup receiving terminal. The first uplink rate, the second uplink rate, and the transmission rate are, for example, 1kb/s, 1000kb/s, and so on.
In the technical solution provided by the present invention, step S120 specifically includes:
the method comprises the steps of presetting a rate acquisition time period, obtaining a first suspension time based on the obtained first current time and the rate acquisition time period, obtaining each first time point from the first current time to the first suspension time and the uplink rate of a first transmission channel of each first time point, and obtaining a plurality of first time point average uplink rates, wherein the average uplink rate of the first transmission channel is the first uplink rate.
According to the technical scheme provided by the invention, when the first uplink rate is obtained, the data transmission rates of a plurality of time points are comprehensively considered, so that the obtained first uplink rate is not the uplink rate at a certain time point and a certain moment.
The rate acquisition time period may be 5 seconds, the first current time may be 16:29:25, the first suspension time may be 16:29:30, and the first time points may include 16:29:25, 16:29:26, 16:29:27, 16:29:28, 16:29:29, and 16:29: 30. Each first time point will have an uplink rate corresponding to it, say 975 kb/s. The invention calculates the average of the uplink rates of the 5 first time points to obtain the average uplink rate, and the average uplink rate of the first transmission channel is the first uplink rate.
And obtaining a second stopping time based on the obtained second current time and the rate acquisition time period, and obtaining each second time point from the second current time to the second stopping time and the uplink rate of the second transmission channel at each second time point to obtain a plurality of second time point average uplink rates, wherein the average uplink rate of the second transmission channel is the second uplink rate.
According to the technical scheme provided by the invention, when the second uplink rate is obtained, the data transmission rates of a plurality of time points are comprehensively considered, so that the obtained second uplink rate is not the uplink rate at a certain time point and a certain moment.
The rate acquisition time period may be 5 seconds, the second current time may be 16:29:25, the second suspension time may be 16:29:30, and the second time points may include 16:29:25, 16:29:26, 16:29:27, 16:29:28, 16:29:29, and 16:29: 30. Each second time point will have an uplink rate corresponding to it, say 975 kb/s. The present invention calculates the average of the uplink rates of the above 5 second time points to obtain the average uplink rate, and the average uplink rate of the second transmission channel is the second uplink rate.
Step S130, obtaining the total downlink rate of the backup receiving end in the first transmission channel and the second transmission channel. The backup receiving terminal is respectively connected with the first backup terminal and the second backup terminal, and sends information and data to the first backup terminal and the second backup terminal. The total downlink rate is the transmission rate at which the backup receiving end receives information and data through the first transmission channel and the second transmission channel. The total downlink rate and the transmission rate are, for example, 1kb/s, 1000kb/s, and so on.
Step S140, determining a first transmission ratio in the first backup terminal and a second transmission ratio in the second backup terminal based on the first uplink rate, the second uplink rate and the total downlink rate, and selecting a first identification number segment and a second identification number segment according to the first transmission ratio and the second transmission ratio.
According to the technical scheme provided by the invention, the first transmission proportion in the first backup terminal and the second transmission proportion in the second backup terminal can be determined according to the first uplink rate, the second uplink rate and the total downlink rate, and the first backup terminal and the second backup terminal can have different working conditions and use states at the current moment, so that the invention can judge the data suitable for transmission of the first backup terminal and the second backup terminal according to the first uplink rate and the second uplink rate, and further ensure that a backup receiving terminal receives the backup information and data in a most efficient and shortest time manner.
In the technical solution provided by the present invention, step S140 specifically includes:
and judging that the total downlink rate is greater than or equal to the sum of the first uplink rate and the second uplink rate. When the total downlink rate is greater than or equal to the sum of the first uplink rate and the second uplink rate, it is proved that the backup receiving terminal can normally receive the information and the data sent by the first backup terminal and the second backup terminal at the first uplink rate and the second uplink rate respectively.
