Description
Technical field
The invention belongs to operating systems to back up field, and in particular to a kind of operating system backup and reduction based on Linux
Method and system.
Background technique
As technology develops, computer, server, industrial personal computer and Embedded Hardware Platform should be increased significantly, and be grasped
As system it is the basis of all hardware platform operation, therefore produces many operating system installations and backup tool, applies at present
It is more widely to be installed by iso mode, system backup is carried out by third party's tool.But this method often has ignored
System safety problem, on the one hand needs to install third party's tool, and operation is also more complicated when on the other hand making iso tool shelf.
This is the deficiencies in the prior art, therefore, in view of the above-mentioned drawbacks in the prior art, is provided a kind of based on Linux's
The method and system of operating system backup and reduction, are necessary.
Summary of the invention
It is an object of the present invention to which complicated defect is installed and backed up for above-mentioned existing operating system, one kind is provided
The method and system of operating system backup and reduction based on Linux, to solve the above technical problems.
To achieve the above object, the present invention provides following technical scheme:
A method of operating system backup and reduction based on Linux include the following steps:
S1. the second operating system is set for server；
S2. (SuSE) Linux OS is backed up；
S3. start (SuSE) Linux OS and judge whether to start successfully；
If so, entering step S6；
If it is not, entering step S4；
S4. start the second operating system；
S5. (SuSE) Linux OS is restored under the second operating system；
S6. terminate.
Further, specific step is as follows by step S1:
S11. the system file of the second operating system is fabricated to image file；
S12. the starting guidance file of the second operating system is made；
S13. file and image file is guided to be burnt in USB flash disk the starting of the second operating system.USB flash disk is made simultaneously as boot disk
For system disk, the safety using third party's tool is avoided.
Further, image file uses the image file of iso format.The image file of iso format is common operation
System image file.
Further, specific step is as follows by step S4:
S41. setting server starts from USB flash disk；
S42. the second operating system in the second os starting guidance file Boot Server starting USB flash disk.Server is set
Start from USB flash disk, while USB flash disk is inserted into server, guarantees USB flash disk starting.
Further, specific step is as follows by step S2:
S21. start (SuSE) Linux OS；
S22. hard disk backup (SuSE) Linux OS needed for selecting.The hard disk where selection (SuSE) Linux OS is had to, may be used also
Select important hard disk.
Further, specific step is as follows by step S22:
S221. file name after the hard disk being backed up under acquisition (SuSE) Linux OS and backup；
S222. fixed disk file catalogue is created, carry is backed up hard disk under fixed disk file catalogue；
S223. it will be backed up after fixed disk file is packaged and compress, and generate backup harddisk file, be named as filename after the backup of acquisition
Claim；
S224. unload carry is backed up hard disk, and deletes the All Files under fixed disk file catalogue.Hard disk as mount point
It can just be used, after backup file generated, to unload the hard disk as mount point.
Further, it will be backed up in step S223 after fixed disk file is packaged with gzip format compression.
Further, specific step is as follows by step S5:
S51. subregion details under the second operating system are checked；
S52. the hard disk where carry backup harddisk file；
S53. enter the hard disk catalogue where backup harddisk file；
S54. the non-concealed file and catalogue under the hard disk catalogue where backup harddisk file are shown；
S55. the hard disk that obtains backup harddisk file and need to restore；
S56. the write-in of backup harddisk file need to be restored into hard disk under the second operating system.
Further, specific step is as follows by step S56:
S561. subregion is carried out to hard disk need to be restored, and define subregion sheet format；
S562. output need to restore fdisk, and need to restore formatting hard disk；
S563. the write-in of backup harddisk file need to be restored into hard disk.
Further, the second operating system is using the debain system after simplifying.
The present invention gives following technical solution:
A kind of system of operating system backup and reduction based on Linux, including
Second operating system setup module, for the second operating system to be arranged for server；
(SuSE) Linux OS backup module, for backing up (SuSE) Linux OS；
(SuSE) Linux OS starts judgment module, for starting (SuSE) Linux OS and judging whether to start successfully；
Second os starting module, for starting the second operating system；
(SuSE) Linux OS recovery module, for restoring (SuSE) Linux OS under the second operating system.
The beneficial effects of the present invention are:
The present invention backs up the hard disk where (SuSE) Linux OS in advance, when (SuSE) Linux OS can not start, passes through second
Operating system carry hard disk, quickly restores to (SuSE) Linux OS, easy to operate simple, practical.
In addition, design principle of the present invention is reliable, structure is simple, has very extensive application prospect.
It can be seen that compared with prior art, the present invention implementing with substantive distinguishing features outstanding and significant progress
Beneficial effect be also obvious.
