The target backup disk is a disk which needs to backup partition table information; the disk information may include: the device number of a disk on a local machine (a computer generally has many hard disks, each hard disk is assigned with an independent number by the computer), a descriptor of the device of the disk in the local system, disk types (IDE, SATA, SCSI, SSD), disk partition formats (MBR, GPT), a disk signature (for MBR format), a disk GUID number (for GPT format), the number of disk partitions, the maximum number of partitions supported by the disk (for GPT format), a disk serial number, the location where the first partition of the disk starts, the total capacity of the disk, and the available capacity of the disk; the database may be located in the cloud.
The partition table information records the size and the initial position of each independent physical area of the hard disk, and is a set of specifications established for better managing the data of the hard disk; the partition table information comprises partition information, the partition table can be used as a table, a plurality of pieces of data exist in the table, one piece of data is equivalent to one piece of partition information, and each piece of partition information comprises a plurality of sub items; the disk partition information in different disk partition formats is different, for example, the disk partition information in MBR format mainly includes: the partition number, the starting position of the partition, the capacity size of the partition, the type of the partition (ntfs or fat32 type), the partition activation state and the number of hidden sectors, and the disk partition information in GPT format mainly includes: the partition number, the starting location of the partition, the size of the capacity of the partition, the type of partition (reserved partition MSR, system partition ESP, base data partition, dynamic partition, etc.), the partition attributes, the name of the partition, the GUID number of the partition, and the number of hidden sectors.
The disk partition table information template in the standardized format is a concept of data structured description, and specifies disk information, partition table information and storage positions of the partition information. The standardized format is a published standardized format, such as json format, xml format, and the like.
Specifically, when data on some computer devices is very important and disaster recovery processing is required, thermal backup of data on a server is required at irregular intervals, including omnibearing backup of information such as disk information, partition table information, an operating system, business data and the like, so that data loss caused by abnormal conditions is avoided.

Therefore, the backup partition table information is mainly used for ensuring that the operating system and the software operating environment of the computer can be well restored and rebuilt to the maximum extent, so that the recovery of other data is facilitated.
When the disk partition table information backup is carried out, the disk information of a target backup disk needing the partition table information backup is read, the disk information comprises the disk type of the target backup disk, and the content of the partition information is determined by the disk type, so that after the disk information is obtained, a processing process corresponding to the disk type is called according to the disk type in the disk information, and the partition table and the partition information are further obtained, wherein the information is a component element of the disk partition table information in a standardized format; and then based on the disk information, the partition table information and a disk partition table information template with a standardized format which specifies the storage position of the disk information, the storage position of the partition table information and the storage position of each partition information, obtaining disk partition table information text data with a standardized format and storing the disk partition table information text data into a database, thereby completing the backup process of the partition table information of the target backup disk.

In the backup process, disk information, partition information corresponding to each disk and volume information in a system are read through an agent program on a target backup disk of computer equipment, the information is correlated, and then according to the disk information, the partition table information and a disk partition table information template in a standardized format, partition table information needing to be backed up is converted into disk partition table information text data in the standardized format for storage and transmission, the disk partition table information is convenient to restore.
In one embodiment, the step 202 of reading the disk information of the target backup disk may include:
and searching all local disks, and selecting the disk needing the backup partition table information as a target backup disk.
Specifically, all the disks on the local computer device can be retrieved through windows api, the windows api interface is the most basic function library provided by microsoft to developers, and although microsoft also provides some tool programs that can retrieve and acquire disk information, these tool programs are also developed using windows api interface, such as microsoft's diskpart program. Therefore, for developing the service of partition information backup and restoration, calling the Windows API is the most direct and effective way. After all local disks are retrieved, the disk needing to backup the partition table information can be selected as a target backup disk, and a subsequent partition table information backup process of the target backup disk can be carried out under the condition that the target backup disk is determined.

step 302, based on the partition table information, obtaining the partition information by traversing the partition nodes;
and step 304, according to a json-format disk partition table information template, filling disk information into a disk json object and filling all partition information into a partition json object to obtain json-format disk partition table information text data.
The standardized format can be a json format or an xml format, but the json format is simpler, the efficiency of the json format is higher, and the processing of the Web front end is more convenient, namely the json data format has the characteristics of high generality, strong readability, easiness in expansion and simplicity, so that the json format is preferentially adopted. The json object is an abstraction of a memory data set concept during program operation, and the json data is used for standardizing and textualizing the data in the content through a json format so as to be convenient to store and transmit.
Specifically, under the condition that the disk information and the partition table information of the target backup disk are read, the partition information can be obtained by traversing each partition boundary node based on the partition table information, the disk information is filled in the json object of the disk according to the disk partition table information template in the json format, and the partition information is filled in the json object of the partition, so that the text data of the disk partition table information in the json format can be obtained.

Specifically, in the process of filling the disk information into the disk json object and filling the partition information into the partition json object according to the disk partition table information template in the json format, the partition format of the target backup disk can be obtained based on the disk information, and a corresponding disk json object is created according to the partition format of the target backup disk; and obtaining the type of the partition based on the partition information, and creating a corresponding partition json object according to the type of the partition. Under the condition that corresponding disk json objects and partition json objects are created, filling all sub-item data in the disk information into the disk json objects according to the meanings of all sub-items in the disk information and a disk partition table information template in a json format, and filling all sub-item data in the partition information into the partition json objects according to the disk partition table information template in the json format and the meanings of all sub-items in the partition information, so that self-expressive structured disk partition table information text data in the json format can be obtained.
The json-format disk partition table information text data displays data in a key value pair mode, the front part is used for describing key words, and the rear part is used for describing values, so that binary data of computer data can be converted into text data which can be easily read and understood by a person even if format description does not exist by the json-format disk partition table information text data; aiming at the partition information with different formats, the whole structure of the data is not influenced by adding or changing the data field, and the problem of structure unification can be solved; the partition table information is backed up and restored by adopting the json format, so that the problems that data cannot be mutually identified among different platforms and the conversion frequency is high can be solved. The method and the device adopt the json data format to backup the disk partition table information, the readability of the data is strong, the data content is convenient to expand, and the intercommunication and mutual recognition among different platforms are realized.
Fig. 4 is a schematic flowchart illustrating a method for backing up information of a disk partition table in a specific example.
