Abstract
The invention relates to the field of cloud computing, in particular to a method for backing up and restoring a Windows virtual machine system disk. The method includes powering off a Windows virtual machine, performing internal snapshotting, and generating backup files; performing system restoration according to a snapshot name, restarting up the Windows virtual machine after restoration is successful, and restoring the system disk of the Windows virtual machine to a state of a backup time point, wherein incremental backup is adopted for the backup files, so that storage space occupied by each backup file is relatively small, repeated snapshotting can be realized, and restoring to any backup point can be realized. By the method, the problems of crashing and breakdown of an operating system due to the fact that the Windows virtual machine is poisoned or attacked maliciously are solved, and stop time of applications and services is reduced as much as possible by restoring the backup files of the virtual machine to enable the virtual machine to restore to the state of the backup point; the method can be applied to backup and restoration of the Windows virtual machine system disk.
Description
Technical field
The present invention relates to cloud computing field, refer in particular to a kind of Windows dummy machine system dish backup and restore method.
Background technology
Under the megatrend of cloud computing development, no matter be physical host or fictitious host computer, particularly moved the Windows main frame of application and service, often face the danger of virus and malicious attack, the probability of delay machine and operating system collapse is higher; Therefore, need to carry out schedule backup to the system disk of Windows, to can quickly recover to the state of backup point after operating system collapse, the time that application and service is stopped shortens as far as possible.
The method of typically Windows host computer system dish being carried out to backup-and-restore is to use ghost software, and the step of backup method is as follows:
1, " a key ghost " software is installed on Windows main frame;
2,, after restarting, when selecting to need the operating system of startup, select " a key ghost ";
3, open ghost, select local->partion->To image, the name of then filling in standby system, as: win2003_r2, selection need to be placed the subregion of Backup Images;
4, after backing up successfully, will see win2003_r2.GHO backup file;
The step of restoration methods is as follows:
1, restart Windows operating system, when login system is selected to start mirror image, select a key ghost;
2, enter ghost interface, after hit OK enters, select local->partion->From image, find win2003_r2.GHO image file, reduction backups to original system dish;
3, after reducing successfully, Windows main frame is normally restarted, and enters after operating system state when C dish returns to backup.
Under cloud computing environment, because the virtual machine of needs backup is more much more than the quantity of physical machine, consider the feature of ghost class software backup method of reducing, can produce following problem:
1, the storage space that backup file takies is larger, because ghost class software adopts full backup, though the space that backup file, through overcompression, takies also reaches 70% of system disk space, in a physical machine, many virtual machines repeatedly back up, and the storage space of use will be very large;
2, the time that virtual machine need to shut down is longer.Because backup file is large, the time that backup recovers is relatively also long, and needs to shut down in backup rejuvenation, and the time that application and service stops will be corresponding elongated;
3,, under mbr damaged condition, can not recover.Because ghost class software itself relies on dos, therefore, when mbr damages, dos can not guide, and ghost also just can not start, and cannot carry out recovery operation.
Therefore, need a kind of special system disk backup-and-restore method for Windows virtual machine.
Summary of the invention
The technical matters that the present invention solves is to provide a kind of Windows dummy machine system dish backup and reduction side
Method, system disk quick backup and the reduction problem of a large amount of Windows fictitious host computers of solution cloud computing environment, the time shorten that application and service is stopped.
The technical scheme that the present invention solves the problems of the technologies described above is:
Backup-step comprises:
Step 1, the Windows virtual machine of outside snapshot operation at host with image file, during establishment, in virtual machine image file all for creating system disk;
Step 2, virtual machine shutdown, fill order, the inside snapshot of establishment virtual machine;
Step 3, checks the SNAPSHOT INFO of virtual machine, confirm back up successfully after virtual machine start continuation move;
Reduction step comprises:
Step 1, in the time of reducing the system disk of virtual machine, shuts down virtual machine;
Step 2, checks the SNAPSHOT INFO of virtual machine, selects the snapshot of certain backup point, carries out snapshot restore order;
Step 3, after being successfully recovered, virtual machine is started shooting again, and the system disk of virtual machine reverts to the state of BACKUP TIME point.
The described virtual machine method of operation is outside snapshot operation, and outside snapshot is that an increment with respect to virtual machine image carries out, and all immediate record is in this outside snapshot to changes all in mirror image for virtual machine, and it is constant that virtual machine image remains;
What described virtual machine backup mode adopted is inner snapshot, is the increment mirror image changing with respect to virtual machine image file sometime, and the data of only preserving dummy machine system increment, do not comprise all files.
Described outside snapshot be one all the time at the file changing, inner snapshot is a mirror image sometime; Outside snapshot only has one, and inner snapshot, as backup file, can exist a plurality of simultaneously.
The inventive method has following beneficial effect:
What 1, the backup mode of the inventive method adopted is incremental backup, do not comprise all files, so the storage space that backup file takies is relatively less.
2, the time that the inventive method backup and reduction needs is relatively less, so the time that the application and service on virtual machine stops is also shorter; Also make in addition timed backup become possibility, little on the impact of business continuance, the practicality of the method is higher.
3, the inventive method, because carry out the outside that backup and reduction operates in VME operating system, is not therefore subject to the restriction of virtual machine interior condition, even if virtual machine image file is damaged completely, can reduce yet.
