It should be noted that, the source computer may be a computer that provides data to be migrated when performing the data migration method, the boot disk may be a disk that performs a booting function when a program is executed, for example, in general, the system is started from a hard disk, when the system is damaged (a virus or a mishandling is deleted), the system is started by using the boot disk, and then the system is repaired or set, where the preset area may be an area of a preset size in the boot disk, the system data may be data in the preset area in the boot disk, and the data disk may be other disks in the source computer except for the boot disk.
Step S20: and recording the position information of the system data in the data disk of the source computer.
It should be noted that the location information may be storage information of the system data in the data disk of the source computer, for example, the first 512MB of the system data is stored in a 1GB area of the data disk, the second 512MB is stored in a 1GB to 2GB area of the data disk, the third 512MB is stored in a 2GB to 3GB area of the data disk, and the fourth 512MB is stored in a 3GB to 4GB area of the data disk, or may be sequentially stored or separately stored in different data disks, and the location information of the system data in the data disk of the source computer may be recorded.
In specific implementation, a data migration program on a source computer searches for available space on the data disk, acquires a data disk with the largest available space in the source computer, creates a temporary file on the data disk with the largest available space, migrates system data in the preset area into the temporary file, and records the position of the temporary file as the position information.
Further, in order to avoid the problem that the system data is lost due to the change of the data in the process of migrating the system data to the data disk, the embodiment further includes monitoring whether the system data in the preset area of the boot disk is changed, and synchronously migrating the changed data to the data disk when the system data is changed, so as to ensure that the system data in the boot disk is consistent with the data migrated to the data disk.
Step S30: and transmitting the position information, the first effective data of the guide disk of the source computer and the second effective data of the data disk of the source computer to a target computer, so that the target computer receives the position information, the first effective data and the second effective data through a preset operating system, and after the first effective data and the second effective data are received, migrating the system data to a preset area of the guide disk of the target computer through the position information, wherein the preset operating system is stored in the preset area of the guide disk of the target computer.
It should be noted that, the target computer may be a computer that receives migration data, the first valid data is valid data in a boot disk in the source computer, the second valid data is valid data in a data disk in the source computer, the preset operating system may be a reduced operating system installed in the target computer for data migration, the preset area may be an area of a preset size in the boot disk in the target computer, and an area of a preset area of the target computer may be the same as an area of a preset area of the source computer.
It should be understood that, during the data migration process, the system is stored in the preset area of the boot disk of the target computer, if the system data is migrated in advance during the migration process, the operating system of the target computer is destroyed, and in this embodiment, after the first valid data and the second valid data are received, the system data are migrated to the preset area of the boot disk of the target computer through the location information. In some cases, the system data of the preset area of the source computer may be migrated, which is not limited herein.
Further, in order to enable the target computer to better receive the migration data sent by the source computer, disk information of a boot disk and a data disk in the source computer can be obtained, and the disk information is sent to the target computer, so that the target computer creates the boot disk and the data disk on the target computer according to the disk information. The disk information may be the number and space size information of the boot disk and the data disk in the source computer, for example, the boot disk in the source computer has 60GB, the data disk has 80GB, 60GB and 40GB, and then the disk information is sent to the target computer, so that the hard disk of the target computer is also configured as the corresponding boot disk 60GB, the data disk is 80GB, 60GB and 40GB, respectively, and during the migration process, the boot disk data in the source computer is migrated to the boot disk of the target computer, the data disk of the 60GB space of the source computer is migrated to the data disk of the target computer, which occupies 60GB space, and so on, in some cases, for example, the hard disk space of the target computer is far greater than the hard disk space of the source computer, and the corresponding disk may also be created reasonably according to the number of the source disk, which is not limited herein.
Further, in order to avoid the problem that data is lost due to the change of data in the migration process, the embodiment further includes monitoring whether the data in the data disk is changed in the migration process, and synchronously migrating the changed data to the target computer when the data is changed.
In the embodiment, system data of a preset area in a boot disk of a source computer is migrated to a data disk of the source computer; recording position information of system data in a data disk of a source computer; the method comprises the steps of sending position information, first effective data of a guide disk of a source computer and second effective data of a data disk of the source computer to a target computer, enabling the target computer to receive the position information, the first effective data and the second effective data through a preset operation system, and after the first effective data and the second effective data are received, migrating system data to a preset area of the guide disk of the target computer through the position information.

It should be noted that the area size may be the space size of the boot disk occupied by the preset operating system installed in the target computer.
It should be understood that, in the migration process, in order not to destroy the original operating system of the target computer, a reduced operating system is installed for the target computer, and the reduced operating system is stored in a preset area of the target computer, in the migration process, if data in the preset area is migrated in advance, the reduced operating system of the target computer is destroyed, and subsequent migration cannot be performed or fails, so in the migration process, in order to implement final migration of the system data in the preset area, the source computer receives the area size of the preset area sent by the target computer, migrates the system data in the preset area to a data disk, and when migration of the first valid data and the second valid data is completed, migrates the system data in the preset area.
Step S02: and determining a preset area of the boot disk of the source computer according to the area size.
It should be understood that the determining the preset area of the boot disk of the source computer according to the area size may determine a specific disk space at the front portion of the boot disk calculated by the source according to the area size, for example, the area size is 2GB, and then the front 2GB space of the boot disk of the source computer is taken as the preset area.
According to the method, the device and the system, the area size sent by the target computer is received, the area size is determined by the target computer according to the space size of the guide disk occupied by the preset operating system, the preset area of the guide disk of the source computer is determined according to the area size by acquiring the area size determined by the target computer according to the space size of the guide disk of the target computer occupied by the preset operating system, and therefore the system data in the preset area of the target computer are not destroyed before the position information, the first effective data and the second effective data are migrated, and the migration process can be smoothly carried out.
