Based on the hardware structure, the embodiment of the operating system restoration method is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the operating system restoring method according to the present invention.
In a first embodiment, the operating system restoring method includes the steps of:
step S10, when the storage space required by the backup data of the operating system partition is larger than that of the boot disk, storing the backup data of the operating system partition into a target non-boot disk, wherein the storage space of the target non-boot disk is larger than that required by the backup data of the operating system partition.
It should be noted that, the os partition backup data is data that needs to be backed up and restored, when a storage space required by the os partition backup data is larger than a storage space of a boot disk, that is, the storage space of the boot disk is not enough to store the os partition backup data, at this time, the os partition backup data may be stored in a target non-boot disk, where the target non-boot disk is a disk that is predetermined to store the os backup data, the storage space of the target non-boot disk is larger than the storage space required by the os partition backup data, that is, the target non-boot disk meets a condition for storing the os partition backup data, the boot disk and the target non-boot disk are computer software objects or hardware objects that can store data, and a common hardware disk includes: memory, flash memory, hard disk, etc.; common software disks are: a virtual memory linear access space, a file system volume, a hard disk partition, a Logical Unit Number (LUN), and the like, which is not limited in this embodiment; the backup data of the partition of the operating system may be default data or data updated in real time, which is not limited in this embodiment.
Further, before the step S10, the operating system restoring method further includes the following steps:
when the restoration process of the backup data starts, acquiring the data capacity of the backup data of the partition of the operating system;
and judging whether the backup data of the partition of the operating system is larger than the storage space of a guide disk or not according to the data capacity.
It should be understood that, the capacity of the backup data of the operating system partition, which is the capacity of the storage space required by the data in the restored operating system partition, may be obtained and recorded from the backup source when the backup data is generated, or may be obtained by analyzing the backup data; and simultaneously, the space capacity of a boot disk of a target computer can be acquired in real time from the target computer, whether the boot disk can store the partition backup data of the operating system can be judged according to the data capacity, if the partition backup data of the operating system can be stored, the partition backup data of the operating system is directly backed up to the boot disk, if the partition backup data of the operating system is found to be stored in a storage space larger than that of the boot disk, the partition backup data of the operating system is stored in a target non-boot disk, and the target non-boot disk performs subsequent backup data restoration operation.
And step S20, writing the target storage address of the backup data of the operating system partition into a boot program in the boot disk.
It can be understood that, after the operating system partition backup data is stored in the target non-boot disk, a current storage address, that is, a target storage address of the operating system partition backup data may be acquired, and after the target storage address is written in a boot program of the boot disk, preparation may be made for importing the subsequent operating system partition backup data.
And step S30, when an operating system starting instruction is received, redirecting the operating system partition backup data in the target non-boot disk by the boot program in the boot disk according to the target storage address.
It should be understood that the os boot instruction is an instruction sent by a target user to boot an os, and when the os boot instruction is received, a redirection operation may be performed, that is, a bootstrap program in the boot disk redirects the os partition backup data in the target non-boot disk according to the target storage address; the operating system starting instruction may be a corresponding disk selection instruction input by a target user through a terminal device, or may be an instruction directly triggered by touching or clicking, or may be an instruction input by other means, which is not limited in this embodiment; the bootstrap program is a preset program for guiding the called operating system partition backup data, and the operating system partition backup data can be accurately acquired through the bootstrap program; the method is convenient for calling the partition backup data of the subsequent operating system, accelerates the data backup speed, and improves the efficiency and the accuracy of the data backup.
It can be understood that the original data backup path is imported from a local disk to the boot disk through the boot program, but since the storage space of the boot disk is not enough to store the operating system partition backup data, the calling disk of the operating system partition backup data can be effectively stored after being redirected from the boot disk to the target non-boot disk, so as to prepare for restoring the subsequent backup data.
And S40, acquiring a system starting program from the operating system partition backup data, and calling the system starting program to start and restore the operating system.
It can be understood that the system boot program is a data file necessary for booting the operating system, and the operating system can be booted and restored by obtaining the system boot program from the backup data of the operating system partition and calling the system boot program, so that the operating system operates normally.
According to the scheme, when the storage space required by the backup data of the operating system partition is larger than that of the boot disk, the backup data of the operating system partition is stored in the target non-boot disk, and the storage space of the target non-boot disk is larger than that required by the backup data of the operating system partition; writing a target storage address of the backup data of the operating system partition into a boot program in the boot disk; when an operating system starting instruction is received, a bootstrap program in the bootstrap disk redirects operating system partition backup data in a target non-bootstrap disk according to the target storage address; acquiring a system starting program from the backup data of the operating system partition; the system startup program is called to start and restore the operating system, the system backup data can be correctly restored without being limited by the size of the system backup data and the size of the magnetic guide disk of the restoration target computer, the consistency and the safety of the restoration of the backup data are ensured, a user can more conveniently restore the backup operation, and the user experience is improved.
Further, fig. 3 is a schematic flowchart of a second embodiment of the operating system restoring method of the present invention, and as shown in fig. 3, the second embodiment of the operating system restoring method of the present invention is proposed based on the first embodiment, and in this embodiment, the step S10 specifically includes the following steps:
and S11, when the storage space required by the backup data of the operating system partition is larger than that of the boot disk, generating and displaying data recovery reminding information.
It can be understood that the data recovery reminding information is reminding information for reminding the target user to store the operating system partition backup data to the target non-boot disk, when the storage space required by the operating system partition backup data is larger than that of the boot disk, the data recovery reminding information can be generated in time, the data recovery reminding information is fed back to the terminal device of the user, and the user can know that the boot disk does not have enough space to store the operating system partition backup data through the data recovery reminding information displayed by the terminal device.
And S12, storing the backup data of the operating system partition into a target non-boot disk after receiving a confirmation instruction of a user.
It should be understood that after receiving a confirmation instruction from a user, the operating system partition backup data may be directly stored in the target non-boot disk, and due to the confirmation of the user, a situation that a user experiences a bad experience due to an autonomous replacement of a storage disk is avoided.
Further, the step S12 specifically includes the following steps:
acquiring the disk capacities of other disks in the target host except the boot disk, and taking the disk with the disk capacity larger than the storage space required by the partition backup data of the operating system as a non-boot disk;
when the number of the non-boot disks is single, taking the non-boot disks as target non-boot disks;
and when the number of the non-boot disks is multiple, respectively calculating the capacity difference between the storage space of each non-boot disk and the storage space required by the backup data of the operating system partition, and taking the non-boot disk with the capacity difference matched with the target capacity difference in the preset disk selection strategy as the target non-boot disk.
It can be understood that the target host is a host capable of running the operating system partition backup data, the target host includes a plurality of disks, and by obtaining disk capacities of other disks in the target host except the boot disk, a non-boot disk whose disk capacity is larger than a storage space required by the operating system partition backup data can be screened out, and then when the number of the non-boot disks is single, the non-boot disk is directly determined as a target non-boot disk, and when the number of the non-boot disks is multiple, a capacity difference between the storage space of each non-boot disk and the storage space required by the operating system partition backup data is respectively calculated, and then the non-boot disk whose capacity difference matches a target capacity difference in a preset disk selection policy is taken as the target non-boot disk, where the preset disk selection policy may take the non-boot disk with the largest capacity difference as the target non-boot disk, may also take the non-boot disk with the smallest capacity difference as the target non-boot disk, and may also determine that the non-boot disk with the largest capacity difference satisfies the target storage space as the target non-boot disk, and this embodiment of course, and this embodiment does not restrict the non-boot disk; the partition backup data of the operating system can be effectively stored, the storage space is saved, the waste of the storage space is avoided, and the data backup cost is saved.
According to the scheme, when the storage space required by the backup data of the partition of the operating system is larger than that of the boot disk, the data recovery reminding information is generated and displayed; after receiving a confirmation instruction of a user, storing the partition backup data of the operating system into a target non-boot disk, particularly when the number of the non-boot disks is multiple, respectively calculating a capacity difference between a storage space of each non-boot disk and a storage space required by the partition backup data of the operating system, and taking the non-boot disk with the capacity difference matched with a target capacity difference in a preset disk selection strategy as the target non-boot disk, so that the condition that bad experience is caused to the user due to the independent replacement of the storage disk is avoided, the backup data reduction efficiency is improved, and the cost for reducing the backup data is saved.
Further, fig. 4 is a schematic flowchart of a third embodiment of the operating system restoring method of the present invention, and as shown in fig. 4, the third embodiment of the operating system restoring method of the present invention is proposed based on the second embodiment, and in this embodiment, the step S20 specifically includes the following steps:
step S21, obtaining a data logical address of the operating system partition backup data in the target non-boot disk, and using the data logical address as a target storage address.
It should be noted that after the operating system partition backup data is stored in the target non-boot disk, there is a corresponding data logical address, and after the data logical address corresponding to the operating system partition backup data is obtained, the data logical address may be used as a target storage address to prepare for subsequent data calling.
And S22, writing the target storage address into a boot program in the boot disk.
It should be understood that, by writing the target storage address into the boot program of the boot disk, subsequent data call can be more convenient and accurate, and the speed and efficiency of restoring the backup data are further increased.
Correspondingly, the step S22 specifically includes the following steps:
and writing the target storage address of the backup data of the operating system partition into the configuration parameters of the bootstrap program in the bootstrap disk.
It should be understood that, writing the target storage address into the boot program, specifically, writing the target storage address of the operating system partition backup data into the configuration parameters of the boot program in the boot disk, and in actual operation, writing the target storage address into the configuration data of the redirection boot program, thereby increasing the speed of storing the backup data.
Further, after the step writes the target storage address of the backup data of the operating system partition into the configuration parameters of the boot program in the boot disk, the operating system restoring method further includes the following steps:
and restarting the bootstrap program in the bootstrap disk so as to enable the configuration parameters of the bootstrap program in the bootstrap disk to take effect.
It can be understood that, by restarting the boot program in the boot disk, the configuration parameters of the boot program in the boot disk can be enabled to take effect, and the operating system is rapidly started and restored by using the operating system partition backup data; in a specific implementation, the bootstrap program is restarted, so that after the configuration parameters take effect, the restored operation partition can be directly known from the configuration parameters, and then the system boot program and the parameters of the system boot program can be acquired from the operation partition, and then the system boot program can be executed according to the parameters, so that the operation system can be started quickly; the redirected bootstrap program can read the system start program with copied and corrected configuration information from the bootstrap disc, and the system start program is executed via the parameters of the system start program to start the operation system fast.
Correspondingly, the step S30 specifically includes the following steps:
and when an operating system starting instruction is received, redirecting the operating system partition backup data in the target non-boot disk by the bootstrap program in the boot disk according to the target storage address in the configuration parameters.
It can be understood that, when an operating system start instruction is received, the boot program in the boot disk redirects the operating system partition backup data in the target non-boot disk according to the target storage address in the configuration parameters, thereby ensuring that the operating system obtains the corresponding configuration parameters required by the operating system start in time when starting, so that the subsequent data call is more convenient and accurate, the subsequent backup restoring operation is facilitated, and the speed and efficiency of the backup restoring data are increased.
According to the scheme, the data logic address of the operating system partition backup data in the target non-boot disk is obtained, the data logic address is used as the target storage address, and the target storage address is written into the boot program in the boot disk, so that subsequent data calling is more convenient and accurate, the speed and the efficiency of backup data restoration are further increased, the time of backup data restoration is saved, and the user experience is improved.
