Description

Backup recovery method and device based on K1 mini-machine operating system

Technical Field

The invention relates to the field of backup recovery of an operating system, in particular to a backup recovery method and device based on a K1 mini-machine operating system.

Background

The current operating system backup and restore methods for K1 mini-servers are not perfect.

There are two main approaches in the prior art: the method I comprises the steps of packaging and compressing a file system of an operating system periodically, and copying and storing a compressed package on a magnetic tape or an external storage. When recovery is needed, starting a server under a simplified version operating system by using a USB flash disk with the simplified version operating system installed, mounting a hard disk with the operating system installed on the server to a file system, copying a previously backed-up operating system compression package to the mounted file system and releasing the content in the compression package, realizing recovery of the hard disk data of the original operating system in such a way, and pulling out the USB flash disk to reboot the server after recovery is finished;

and secondly, backing up the operating system by using third-party backup software (such as NBU), wherein the backup software directly backs up the file system of the operating system to a storage or tape library by backing up the file system of the operating system. When the operation system needs to be restored, the operation system is firstly reinstalled on the server, and then the file system covering the new operation system is restored from the storage or the tape library by the backup operation system files, so that the purpose of restoring the operation system to the original state is achieved.

The two backup recovery methods have the following problems: on one hand, the backup is only at a file level, but not at a mirror image level of the whole operating system, so that the file needs to be restored firstly when the backup is restored, and then the operating system is restored by using the restored file; when the number of computing partitions is large, the backup and recovery operation method is complicated, the recovery time is too long, and the implementation of the backup and recovery method needs to depend on other hardware, such as an SMC (system manager control, a system management control module, and an independent module in a minicomputer for controlling and managing each partition, so that the backup and recovery method is not suitable for a real environment, cannot perform batch operation of backup and recovery of the computing partitions, and is not efficient.

It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the invention.

Example one

As shown in fig. 1, the present invention provides a backup recovery method based on K1 mini-machine os, including:

s1, setting a server backup recovery module in a computing partition of the small-sized computer, setting a client backup recovery module in the computing partition to be backed up and recovered, and connecting the server backup recovery module with the client backup recovery module through a network;

s2, the server side backup recovery module acquires the computing partition to be backed up, and performs mirror image backup operation on the operating systems of the computing partition to be backed up in batch through a first command to correspondingly generate a plurality of backup files;

s3, during recovery, the server side backup recovery module obtains the name of the node of the computing partition to be recovered and the corresponding backup file, and performs defined recovery operation on the backup file corresponding to the operating system of the computing partition to be recovered through a second command; the client side backup recovery module opens the BMC in the computing partition to be recovered, acquires a backup file defining recovery operation through a network, and recovers the backup file into a system disk of the computing partition to be recovered.

In step S1, the computing partition to be backed up and restored and the computing partition where the server backup and restore module is located may be located in the same and/or different K1 minicomputers, that is, the computing partition where the server backup and restore module is located in this scheme may manage backup and restoration of the computing partition in the K1 mainframe itself, and may also manage backup and restoration of the computing partitions in other K1 mainframes. And the server side backup recovery module is in communication connection with the second script through a network. The specific implementation mode of the server side backup recovery module is as follows: packaging a K-Bak-Server program into a first script, wherein the first script is arranged in a calculation partition in the minicomputer; the specific implementation mode of the client backup recovery module is as follows: and packaging the K-Bak-Client program into a second script, wherein the second script is arranged in the computing partition to be backed up and restored.

In step S2, the server-side backup recovery module (first script) connects each to-be-backed computing partition through the network, and the information of each to-be-backed computing partition on which the second script has been installed may be queried through a third command K-Bak-l (-l indicates all to-be-backed computing partitions in which the client-side backup recovery module (second script) has been set), where the computing partition node name (node) is unique.

And executing the backup operation on the operating system of the computing partition to be backed up. The client backup recovery module (second script) uses a first command K-Bak-m node (-m) to back up a partition, the node represents the name of a computing partition node to be backed up, a specific node (node) name can be inquired by using a third command) to carry out mirror image level backup on an operating system of the computing partition, the first command can be executed for multiple times, a backup file generated correspondingly each time has unique ID and time, the server backup recovery module (first script) can acquire the backup file from the computing partition to be backed up through network communication with the client backup recovery module (second script) while executing the backup, and store the backup file in the computing partition where the server backup recovery module (first script) is located, the specific naming format and path can be/K-Bak/node/node _ Bak _ file _00001, in order to enable the computing partition where the server side backup recovery module (first script) is located to have enough disk space, the backup file is stored in an external storage server connected with the computing partition where the server side backup recovery module (first script) is located; in addition, more network read-write flow is occupied during backup, and backup operation is performed when the service is idle.

Examples are as follows: the server side backup recovery module (first script) performs mirror backup of the operating system of the single computing partition orcl01 through a first command (node name orcl 01):

K-Bak-m orcl01

the path command (node name: orcl01) is saved in the computing partition where the server side backup recovery module (first script) is located for the backup file correspondingly generated by the operating system of the single computing partition orcl01 as follows:

/k-bak/orcl01/orcl_bak_file_00001

the first command is specifically that when the operating system of the computing partition to be backed up executes the batch backup operation: K-Bak-mNode01, node02 … node20(-m indicates that partitions are backed up, node indicates the name of a computing partition node to be backed up, and a specific node name can be queried by using a third command), operating systems of a plurality of computing partitions are backed up simultaneously and can be performed in parallel, the first command can be executed for a plurality of times, and each generated backup file has a unique ID and time.

Specifically, when a backup operation needs to be performed on an operating system of a to-be-backed computing partition with a node name of orcl01-orcl05, the first command is:

K-Bak-m orcl01，orcl02，orcl3，orcl04，orcl05

further, if the operating systems of multiple computing partitions are backed up simultaneously, a maximum of 20 partitions may be limited per backup in view of backup efficiency issues.

Managing backup files: and checking all backup files of the computing partition to be backed up by using a fourth command K-Bak-s node (-s) which indicates checking all backup files of the computing partition to be backed up, and a node which indicates checking the name of the node of the computing partition to be backed up, wherein the backup files have unique ID and time, and deleting the backup files with ID of 1 by using a fifth command K-Bak-s node-d 1(-d which indicates deleting the backup files and 1 which indicates deleting the backup files with ID of 1).

In step S3, the operating system is abnormal due to the damage of the server disk, the mistaken deletion of the operating system file, and the like, and the operating system needs to be recovered. The server side backup recovery module (first script) firstly determines the name of a computing partition node to be recovered and a corresponding specific backup file, and then uses a fourth command K-Bak-s node command to query the backup condition of the partition operating system, wherein each operating system backup file has a unique ID number.

And performing definition recovery operation on the backup file corresponding to the operating system of the computing partition by using a second command K-Bak-s node-r 1(-r represents that recovery operation is defined on the partition, and 1 represents that the backup file with the ID of 1 is defined to the node partition) in the computing partition where the server side backup recovery module (the first script) is located.

Examples are as follows: a defined restore is made to a single to-be-restored compute partition orcl01 using a backup file with an ID of 1 (named orcl 01):

K-Bak-s orcl01–r 1

further, the definition restore generally supports sequential operations, and if it is necessary to define restore for multiple to-be-restored computing partitions, it needs to be performed sequentially, where the sequential execution order may be an order of backing up file IDs, or other orders, and this scheme is not limited herein.

If, for example, orcl01 uses a backup file with ID 1, orcl02 uses an ID 2, and orcl03 uses a backup file with ID 5 to define recovery (node names orcl01, orcl02, and orcl03, respectively) for multiple compute partitions to be recovered, the second command is specifically:

K-Bak-s orcl01–r 1

K-Bak-s orcl02–r 2

K-Bak-s orcl03–r 5

the client side backup recovery module (second script) opens the BMC in the computing partition to be recovered, starts the computing partition to be recovered, and the BMC in the computing partition to be recovered designates the IP information of the computing partition where the server side backup recovery module (first script) is located, so as to ensure the normal communication of the network, so that the client side backup recovery module (second script) can obtain a backup file defining the recovery operation through the network and recover the backup file into a partition system disk.

Further, the method can support simultaneous recovery operation for a plurality of different to-be-recovered computing partitions in batch, and only needs to additionally open the BMC in the to-be-recovered computing partition and start the to-be-recovered computing partition, and operates according to the step S3, specifically, considering the recovery efficiency problem, and restricts up to 10 computing partitions by simultaneous operation each time. And after the recovery is finished, the operating system of the computing partition can be normally logged in.

It should be noted that in this embodiment, the computing partition to be backed up and restored, the computing partition to be backed up, and the computing partition to be restored correspond to the same computing partition, and only the corresponding task stages have different steps, before the computing partition to be backed up and restored corresponds to the computing partition for backup restoration, a client backup restoration module (a second script) is set inside the computing partition, and the server backup restoration module is connected with the client backup restoration module through a network; the computing partition to be backed up is provided with a client backup recovery module (a second script) corresponding to the computing partition, and the server backup recovery module is connected with the client backup recovery module through a network to prepare for executing backup operation; the computing partition to be restored has completed the backup operation corresponding to the operating system of the computing partition, and is ready to perform the restore operation.

According to the invention, the server side backup recovery module (first script) and the client side backup recovery module (second script) are respectively arranged in different calculation partitions, and the server side backup recovery module (first script) is communicated with the server side backup recovery module (first script), so that the backup recovery time is short, and the backup recovery is independent of hardware such as an SMC (sheet molding compound) module, and the efficiency of the backup recovery of the K1 mini-type computer operating system is effectively improved.

The backup file has the unique ID, so that the backup file corresponding to the operating system can be accurately and quickly positioned when the backup file is restored conveniently, and the restoring time is further saved.

The backup file is stored in the external storage server connected with the computing partition where the server side backup recovery module (first script) is located, so that the computing partition where the server side backup recovery module (first script) is located can have sufficient storage space, and the backup operation of the invention is operated when the service is idle because more network read-write flow is occupied during the backup.

The backup and recovery operations of the invention can realize batch simultaneous operation through commands, thus improving the backup and recovery efficiency.
