Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, fig. 1 is a schematic flowchart illustrating a step flow of an embodiment of a backup and recovery method based on a K-UX system according to an embodiment of the present invention; fig. 2 is a schematic flowchart illustrating steps of another specific implementation of a backup and recovery method based on a K-UX system according to an embodiment of the present invention.
In a specific embodiment, the method for backup and recovery based on the K-UX system includes:
step 1, connecting a hard disk externally on a server as a backup disk, and backing up a K-UX system of the server to the backup disk by adopting dd and tar;
step 2, thoroughly destroying the K-UX system;
and 3, restoring the K-UX system through dd and tar.
By adopting a mode of combining dd and tar for backing up the K-UX system, the compressed backup space can be considered, the reliability of system recovery can be improved, the maintenance efficiency of the system is improved, and the maintenance cost is reduced.
In order to further improve the efficiency of the system backup, in an embodiment of the present invention, the boot efi file in the system disk and the file of the root partition (containing data) are backed up in two areas of the backup disk, respectively, that is, step 1 includes:
externally connecting a hard disk on the server as a backup disk, and dividing the backup disk into a first area and a second area;
copying a boot efi file of a K-UX system of the server to a first area of the backup disc by dd;
and compressing the root partition file of the K-UX system of the server by adopting tar and copying the compressed root partition file to a second area of the backup disc.
By partitioning the backup disc, the start guide efi file and the root partition file are copied to the designated area of the backup disc, so that the two files can be simultaneously executed due to different operation areas in the operation process, the backup efficiency is greatly improved, the time required by backup is reduced, and the maintenance efficiency of the system is improved.
In the present invention, in the process of backing up and recovering a system, the original system needs to be damaged and removed, so that the original system does not affect the normal operation of the new system, and the utilization efficiency of the storage space can be reduced, therefore, in an embodiment of the present invention, the step 2 includes:
uninstalling the backup disc from the server;
and completely damaging the K-UX system by using rm.
The backup disc is unloaded from the server first, so that the possible damage to the backup system in the backup disc when the K-UX system is completely damaged by the rm in the follow-up process is avoided, the original K-UX system can be directly executed with all deletion instructions without area division and selection, and the reliability of the backup system is improved.
In order to improve flexibility and security of operation, in an embodiment of the present invention, the step 3 includes:
connecting a second storage with a second system installed with the server;
starting the server, and mounting the damaged second system and the backup disc on the second system;
copying the boot efi file backed up on the first area of the backup disc to an area of the system disc that is damaged using dd;
and decompressing the root partition file of the second area on the backup disc to the damaged second area of the system disc by adopting tar.
By adopting the second memory installed with the second system to operate independently, the flexibility of system recovery can be improved. The second system herein copies the startup boot efi file backed up in the first area of the backup disc to a damaged area of the system disc by dd after the damaged system disc and the backup disc are hung; and decompressing the root partition file of the second area on the backup disc to the damaged second area of the system disc by adopting tar, so that the recovery of the K-UX system can be realized.
It should be noted that, in the present invention, K1 is a high-end fault-tolerant server in the wave tide, K-UX wave is a Linux operating system developed by self, dd is a replication technique in the K-UX system, tar is a compression command in the K-UX system, and rm is a deletion command in the K-UX system.
The method for backing up and recovering based on the K-UX system is not only suitable for the Linux operating system, but also suitable for backing up and recovering other systems.
In order to further implement the detection of possible operation errors in the backup and recovery of the system and improve the efficiency of system maintenance, after the step 3, the method further includes:
and 4, taking dd copying, tar compressing and decompressing and rm deleting of the K-UX system as log records and outputting the log records.
By recording and outputting the instructions received by the K-UX system in the whole process of carrying out system backup and recovery, the fault reason can be quickly positioned when a new system fault occurs, and the reliability of system recovery is improved.
After the step 4, judging whether operation instructions of dd copying, tar compressing and decompressing or rm deleting for the K-UX system occur;
and if so, verifying the operation instruction, and executing the operation instruction after the verification is passed.
By performing instruction verification in the process of system backup and recovery, it is clear that the operator with the authority is performing system backup, but other operators do illegal operations, the possibility of system data loss can be reduced, and the safety of system data is ensured.
The second memory is a U disk or the hard disk.
In order to further improve the flexibility of system recovery, the second memory is a U disk, and the storage space of the U disk is 8-16G. Of course, the space of the usb disk herein refers to the space that can be used actually, and the storage space thereof can be reasonably selected according to the total amount of data of the boot file and the root partition. The U disk is used for system recovery, the U disk system operates independently, and the flexibility and the safety of operation are improved.
In summary, according to the method for backing up and recovering based on the K-UX system provided by the embodiment of the present invention, the K-UX system is backed up by combining dd and tar, so that not only the backup space can be compressed, but also the reliability of system recovery can be improved, the maintenance efficiency of the system is improved, and the maintenance cost is reduced.
The backup and recovery method based on the K-UX system provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts.
