Description
Technical Field
The invention relates to the technical field of computers and information, in particular to a backup restoration method for a Linux desktop operating system.
Background
Fsarchiver is a system archive tool that can compress the contents of an entire file system into one file and then restore the contents of the file system on partitions of different sizes, even systems of different files. Unlike the tar archive tool, fsarchifter also creates a file system when restoring data to a partition.
In order to protect the data at the time of archiving, fsacrcoverer checks the contents of all data. If a file is corrupted during archiving, fsearchiever discards the file and archives other files.
However, Fsarchiver can only back up the contents of the partition that is not mounted or is only read-mounted during the backup, and it cannot back up the contents of the partition that is mounted by reading and writing, so Fsarchiver cannot be used to back up a system that is being used.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides a backup restoration method of a Linux desktop operating system, which comprises the following steps:
s1: modifying an entrance interface of an installation program of the Linux desktop operating system to provide an entrance of a backup restoration interface, so that when an optical disc is inserted, a pop-up interface comprises a window button for backup restoration;
s2: writing a backup button and a restore button;
s3: compiling a backup window;
s4: compiling a window which is being backed up, and compiling a backup function by using Fsarcover;
s5: writing a restored window based on step S2;
s6: and writing a window being restored, and writing a restored function by using Fsarcover.
In step S1, the partition of the backup file is mounted while the optical disc is inserted.
In step S3, the file name generated by the backup is displayed in the window of the created backup.
In step S4, after the backup is completed, all the mounted partitions are unloaded, and then the completion of the backup is prompted through a window.
In step S5, the backup node is displayed in the written restore window.
In step S5, the backup file of the designated node is selected and restored.
Wherein the step S6 further includes: and regenerating grub for guiding the restored Linux desktop operating system, unloading all mounted partitions after restoration is finished and prompting that restoration is finished.
In the invention, the term "Fsarchiver" refers to a safe and flexible file system backup and deployment tool.
The backup restoration method of the Linux desktop operating system provided by the invention can start a LiveCD system environment by using an optical disk when backing up the system, and then backups the system on the partition which is not mounted. The backup and restoration function of the linux desktop operating system is realized.

Detailed Description
In order to further understand the technical scheme and the beneficial effects of the present invention, the following detailed description of the technical scheme and the beneficial effects thereof is provided with the accompanying drawings.
Fig. 1 is an operation flow chart of a method for backup restoration of a Linux desktop operating system according to the present invention, and as shown in fig. 1, the present invention provides a method for backup restoration of a Linux desktop operating system, including the following steps:
s1: modifying an entrance interface of an installation program of the Linux desktop operating system to provide an entrance of a backup restoration interface, so that when an optical disc is inserted, a pop-up interface comprises a window button for backup restoration;
s2: writing a backup button and a restore button;
s3: compiling a backup window;
s4: compiling a window which is being backed up, and compiling a backup function by using Fsarcover;
s5: writing a restored window based on step S2;
s6: and writing a window being restored, and writing a restored function by using Fsarcover.
Preferably, in step S1, the partition of the backup file is mounted while the optical disc is inserted.
Preferably, in step S3, the file name generated by the backup is displayed in the window of the created backup.
Preferably, in step S4, after the backup is completed, all the mounted partitions are unloaded, and then the completion of the backup is prompted through a window.
Preferably, in step S5, the written restore window displays the backed-up node.
Preferably, in step S5, the backup file of the designated node is selected to be restored.
Preferably, the step S6 further includes: and regenerating grub for guiding the restored Linux desktop operating system, unloading all mounted partitions after restoration is finished and prompting that restoration is finished.
In the present invention, the term "grub" refers to a multiple os boot manager.
When the method for backup restoration of the Linux desktop operating system provided by the invention is specifically implemented, the inventor provides the following two specific embodiments:
example 1: and realizing a backup and restoration function on the operating system of the winning kylin desktop.
S1: and modifying an inlet interface of an installation program of the winning bid kylin operating system, wherein the interface comprises a window for backup and restoration, and the window can be popped up when the optical disc is inserted. Then the sda4 partition in the system is mounted, which partition was created at installation time. A backup directory is created on the sda4 partition to save the backup-generated files.
S2: two window buttons are written for backup and restore. If the user selects the backup button, the system will be backed up, and if the user selects the restore button, the backed-up file will be restored.
S3: and writing a backup window, and displaying a file name generated by backup, such as Neokylin-backup-20160910.fsa, in the window.
