Therefore, operators provide users with storage space through disk storage systems, so that users can store more The data.
磁盘存储系统中使用磁盘来存储数据，技术人员会将磁盘封装成多个LUN(LogicalUnitNumber，逻辑单元号)设备。在磁盘存储系统的使用过程中，经常需要对已存储的数据进行备份，这时，需要将磁盘中的某个LUN设备中存储的数据进行备份，存储到其他LUN设备中。In a disk storage system, disks are used to store data, and technicians will encapsulate the disks into multiple LUN (LogicalUnitNumber, Logical Unit Number) devices. During the use of the disk storage system, it is often necessary to back up stored data. At this time, the data stored in a certain LUN device in the disk needs to be backed up and stored in other LUN devices.
在实现本发明的过程中，发明人发现现有技术至少存在以下问题：In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art:
在对数据进行备份时，需要对整个LUN设备进行备份，因此，当需要对LUN设备中的部分数据进行备份时，仍要对该分区所属的整个LUN设备进行备份，这样会占用大量的存储资源。When backing up data, the entire LUN device needs to be backed up. Therefore, when part of the data in the LUN device needs to be backed up, the entire LUN device to which the partition belongs must still be backed up, which will occupy a large amount of storage resources. .

实施例二Embodiment two
本发明实施例提供了一种备份数据的方法，该方法的执行主体为服务器。其中，服务器可以是磁盘存储系统的服务器。如图2所示，为本发明实施例的系统框架图，其中包括磁盘存储系统和终端。The embodiment of the present invention provides a method for backing up data, and the execution body of the method is a server. Wherein, the server may be a server of a disk storage system. As shown in FIG. 2, it is a system frame diagram of the embodiment of the present invention, which includes a disk storage system and a terminal.
下面将结合具体实施方式，对图1所示的处理流程进行详细的说明，内容可以如下：The processing flow shown in FIG. 1 will be described in detail below in conjunction with specific implementation methods, and the content may be as follows:
步骤101，磁盘存储系统接收终端发送的携带有第一待备份分区对应的分区标识和逻辑单元号LUN设备标识的备份请求。Step 101 , the disk storage system receives a backup request from a terminal that carries a partition identifier and a logical unit number (LUN) device identifier corresponding to the first partition to be backed up.
在实施中，用户可以在终端安装用于管理磁盘存储系统的应用程序，用户可以通过该应用程序对终端在磁盘存储系统中对应的存储空间进行分区，也可以通过该应用程序对磁盘存储系统中的分区进行备份。当用户需要将终端在磁盘存储系统中的某分区(即第一待备份分区)进行备份时，可以在终端打开该应用程序，然后在该应用程序中选择该分区，终端则会接收到对应该分区的选择指令，然后向磁盘存储系统发送备份请求，该备份请求中携带有该分区对应的分区标识和LUN(LogicalUnitNumber，逻辑单元号)设备标识，磁盘存储系统则会接收到该备份请求，并对该备份请求进行解析，获取该备份请求中携带的该分区对应的分区标识和LUN设备标识。In the implementation, the user can install an application program for managing the disk storage system on the terminal, and the user can use this application program to partition the corresponding storage space of the terminal in the disk storage system, or use this application program to partition the storage space in the disk storage system. partition for backup. When the user needs to back up a partition of the terminal in the disk storage system (that is, the first partition to be backed up), he can open the application program on the terminal, and then select the partition in the application program, and the terminal will receive the corresponding Partition selection command, and then send a backup request to the disk storage system, the backup request carries the partition ID and LUN (LogicalUnitNumber, Logical Unit Number) device ID corresponding to the partition, the disk storage system will receive the backup request, and The backup request is parsed to obtain the partition identifier and LUN device identifier corresponding to the partition carried in the backup request.
可选的，可以先确定磁盘存储系统的各LUN设备中的各分区在磁盘中对应的起始地址和结束地址。Optionally, the start address and end address corresponding to each partition in each LUN device of the disk storage system on the disk may be determined first.
在实施中，各LUN设备中预先存储有各分区的分区信息，分区信息可以包括各分区在磁盘存储系统中的磁盘中对应的起始地址、结束地址和分区的存储量中的两项或多项。各分区的分区标识及这些分区对应的分区信息可以以分区信息表的形式进行存储。当用户在终端打开用于管理磁盘存储系统的应用程序时，该应用程序可以向磁盘存储系统发送查询请求，磁盘存储系统则会接收到该查询请求，然后可以确定磁盘存储系统的各LUN设备中的各分区在磁盘中对应的起始地址和结束地址。磁盘存储系统中分区的分区格式可以是多样的，如分区格式可以为MBR(MasterBootRecord，主引导记录)分区格式和GPT(GloballyUniqueIdentifierPartitionTableFormat，全球唯一标识符分区格式)分区格式。磁盘存储系统可以先获取各LUN设备的分区格式，然后可以根据不同的分区格式以及该LUN设备的分区信息表，解析出各LUN设备中的各分区在磁盘中对应的起始地址和结束地址，然后将解析出的各LUN设备中的各分区在磁盘中对应的起始地址和结束地址发送给终端，以便用户选择待备份分区。In the implementation, the partition information of each partition is pre-stored in each LUN device, and the partition information may include two or more of the corresponding start address, end address and storage capacity of each partition in the disk in the disk storage system. item. The partition identification of each partition and the partition information corresponding to these partitions may be stored in the form of a partition information table. When the user opens the application program for managing the disk storage system on the terminal, the application program can send a query request to the disk storage system, and the disk storage system will receive the query request, and then can determine the location of each LUN device in the disk storage system. The corresponding start address and end address of each partition in the disk. The partition format of the partition in the disk storage system can be various, such as the partition format can be MBR (MasterBootRecord, master boot record) partition format and GPT (GloballyUniqueIdentifierPartitionTableFormat, globally unique identifier partition format) partition format. The disk storage system can first obtain the partition format of each LUN device, and then analyze the corresponding start address and end address of each partition in each LUN device in the disk according to different partition formats and the partition information table of the LUN device. Then, the parsed start address and end address corresponding to each partition in each LUN device in the disk are sent to the terminal, so that the user can select the partition to be backed up.
例如，磁盘存储系统获取某LUN设备的分区的分区格式为MBR分区格式，则可以先判断该LUN设备上是否有分区，如果该LUN设备上存在分区，则磁盘存储系统可以进一步判断该LUN设备是否包括扩展分区。具体地，磁盘存储系统可以判断各分区信息表中04H位置的标识符是否为0x0F或者0x05，如果是，则说明该LUN设备包含扩展分区，然后可以获取扩展分区的分区格式，进而可以获取扩展分区的分区信息表，分区格式为MBR分区格式的分区中，分区信息表中存储有该LUN设备中所有分区的分区起始地址和分区的存储量，磁盘存储系统可以根据分区起始地址和分区的存储量，计算出各分区的结束地址，磁盘存储系统还可以对获取到的分区格式和分区信息进行存储，以便后续使用。另外，如果分区信息表中04H位置的标识符为0x0F和0x05以外的标识符，则说明该LUN设备中不存在扩展分区，然后可以进行上述计算处理。For example, if the disk storage system obtains the partition format of the partition of a LUN device as the MBR partition format, it can first determine whether there are partitions on the LUN device. If there are partitions on the LUN device, the disk storage system can further determine whether the LUN device has Including extended partitions. Specifically, the disk storage system can determine whether the identifier at position 04H in each partition information table is 0x0F or 0x05, if yes, it means that the LUN device contains an extended partition, and then the partition format of the extended partition can be obtained, and then the extended partition can be obtained In the partition information table of the partition format of the MBR partition format, the partition information table stores the partition start addresses and partition storage capacity of all partitions in the LUN device. The disk storage system can The storage capacity is calculated by calculating the end address of each partition, and the disk storage system can also store the obtained partition format and partition information for subsequent use. In addition, if the identifier at position 04H in the partition information table is an identifier other than 0x0F and 0x05, it means that there is no extended partition in the LUN device, and then the above calculation process can be performed.
又如，磁盘存储系统获取某LUN设备的分区的分区格式为GPT分区格式，分区格式为GPT分区格式的分区中，分区信息表中存储有该LUN设备中所有分区的起始地址和结束地址，磁盘存储系统获取各分区的起始地址和结束地址，然后进行存储，以便后续使用。For another example, the disk storage system obtains the partition format of the partition of a LUN device in the GPT partition format, and in the partition format of the GPT partition format, the partition information table stores the start addresses and end addresses of all partitions in the LUN device. The disk storage system obtains the start address and end address of each partition, and then stores them for subsequent use.
步骤102，磁盘存储系统根据第一待备份分区对应的分区标识和LUN设备标识，确定第一待备份分区的存储量。Step 102, the disk storage system determines the storage capacity of the first partition to be backed up according to the partition identifier and the LUN device identifier corresponding to the first partition to be backed up.
在实施中，磁盘存储系统获取到备份请求中的第一待备份分区对应的分区标识和LUN设备标识后，可以根据第一待备份分区对应的LUN设备标识，确定第一待备份分区对应的LUN设备，进而可以根据第一待备份分区对应的分区标识，在该LUN设备的分区信息表中进行查询，确定第一待备份分区对应的起始地址和结束地址，进而可以确定第一待备份分区的存储量。In implementation, after the disk storage system obtains the partition identifier and LUN device identifier corresponding to the first partition to be backed up in the backup request, it can determine the LUN corresponding to the first partition to be backed up according to the LUN device identifier corresponding to the first partition to be backed up device, and then according to the partition identifier corresponding to the first partition to be backed up, query in the partition information table of the LUN device to determine the start address and end address corresponding to the first partition to be backed up, and then determine the first partition to be backed up storage capacity.
步骤103，在本地的各分区中，确定存储量大于或等于第一待备份分区的存储量的分区，向终端发送携带有确定出的分区对应的分区标识和LUN设备标识的查询消息。Step 103, among the local partitions, determine the partition whose storage capacity is greater than or equal to the storage capacity of the first partition to be backed up, and send a query message carrying the partition ID and LUN device ID corresponding to the determined partition to the terminal.
在实施中，磁盘存储系统确定第一待备份分区的存储量后，可以在本地的各分区中进行查询，确定存储量大于或等于第一待备份分区的存储量的分区，进而可以获取这些分区对应的分区标识和LUN设备标识，然后可以向终端发送查询消息，查询消息中携带有这些分区对应的分区标识和LUN设备标识，终端则会接收到该查询消息，然后可以对该查询消息进解析，获取该查询消息中的分区对应的分区标识和LUN设备标识，并对获取到的分区标识和LUN设备标识进行显示，用户可以根据自身的需要选择分区(即第一目标分区)，终端则会接收到对应该分区的选择指令，然后向磁盘存储系统发送选择消息，该选择消息中携带有第一目标分区对应的分区标识和LUN设备标识。另外，磁盘存储系统还可以确定与自身建立业务关系的其他存储系统中，存储量大于或等于第一待备份分区的存储量的分区，向终端发送携带有这些分区对应的分区标识和LUN设备标识的查询消息。用户可以根据自身的需要选择本存储系统中的其他分区或者LUN设备作为第一目标分区，也可以选择其他存储系统上的分区和LUN设备作为第一目标分区。In implementation, after the disk storage system determines the storage capacity of the first partition to be backed up, it can query the local partitions to determine the partitions whose storage capacity is greater than or equal to the storage capacity of the first partition to be backed up, and then obtain these partitions Corresponding partition IDs and LUN device IDs, and then you can send query messages to the terminal, the query messages carry the partition IDs and LUN device IDs corresponding to these partitions, the terminal will receive the query message, and then you can analyze the query message , obtain the partition ID and LUN device ID corresponding to the partition in the query message, and display the obtained partition ID and LUN device ID. The user can select a partition (that is, the first target partition) according to his own needs, and the terminal will After receiving the selection instruction corresponding to the partition, a selection message is sent to the disk storage system, and the selection message carries the partition identifier and the LUN device identifier corresponding to the first target partition. In addition, the disk storage system can also determine the partitions whose storage capacity is greater than or equal to the storage capacity of the first partition to be backed up in other storage systems with which it has established a business relationship, and send to the terminal carrying the partition identifiers and LUN device identifiers corresponding to these partitions query message. Users can select other partitions or LUN devices in the storage system as the first target partition according to their own needs, or select partitions and LUN devices on other storage systems as the first target partition.
