Abstract
The invention provides a backup virtualization-based method. The method provides a unique backup solution, and real-time backup of a virtual image can be realized without pausing system IO reading-writing; a Windows virtual machine image does not depend on a shadow volume, Linux image backup does not depend on a VM snapshot, a backup format is compatible with a VMDK of a virtual machine, is immediately recovered after backup and is completely consistent with a format of the VM snapshot, and multi-version automatic management of the virtual machine image is realized. The recovery of a single data file in an image volume can be realized. A new method is provided for secure and quick recovery of information.
Description
Technical field
The present invention relates to a kind of method based on backup virtualization, belong to Computer Data Security process field.
Background technology
One day becoming more and more important at data message, data increasingly become enterprise, indispensable in public institution's daily operation
Few part and the foundation of managerial decision.But, the arrival of big data also brings some losses to us, that is, data
Lose and destroyed.In order to prevent loss and the damage that computer data and application etc. cause because of computer glitch, thus
In original text, program or the duplicate of the document of independent independent storage just referred to as back up.Based on virtualized backup recent research table
Bright, virtualization not only research, test and the deployment to Novel Internet architecture has great importance, to NE
The virtualization of (such as router) also can improve its fault redundance, persistently provides the ability of network service, meanwhile, based on standby virtual
The technology changed can utilize the existing transmittability of network, transfers data in the storage system of far-end so that backup is no longer
Need two identical equipment, effectively reduce hardware and put into.So a kind of method based on backup virtualization meet the tendency and
Raw.The method of this data protection is that enterprise provides a kind of means intelligent, automatic, safe and reliable.
The feature of backup virtualization：
1. cloud backup granularity is timed backup task, and after timed backup task generates new BACKUP TIME point, system can
Automatically newly-increased BACKUP TIME point is synchronized to high in the clouds.
2. support cloud backup data store strategy, by arranging the copy sum backuping to high in the clouds, the storage of control high in the clouds
Backup Data total amount.
3. support reversely to replicate, return to high in the clouds data in local medium server.Recover granularity and support backup tasks
All time points or appointment time point data.
4. support breakpoint transmission, when the situation of accidental interruption occurs in Backup Data synchronizing process, the automatic record of system
Lower break period point, when next time initiates synchronization, will be synchronized from breakpoint location, promote synchronous efficiency.
Content of the invention
The invention provides a kind of method based on backup virtualization, this method provide the backup solution of uniqueness,
In the case of not needing Break-Up System IO read-write, it is possible to achieve backing up in realtime of virtualization reflection；Windows virtual machine image
Being independent of shade volume, Linux reflection backup is independent of VM snapshot, and backup format is compatible with virtual machine VMDK, extensive immediately after backup
Multiple and completely the same in accordance with the form provided soon with VM, it is achieved virtual machine image multi version manages automatically.It is capable of single number in reflection volume
Recovery according to file.Recovery safely and fast to information provides a kind of new method.
The framework of backup virtualization can increase and decrease function easily, provides the support to numerous application, as virtual in VM Ware
Machine, Oracle, Sybase and etc..For the applied environment of user, backup virtualization possesses backup outstanding, powerful, manageable
And storage function, it is mainly manifested in following aspect：
1. soft or hard integral structure, integrate backup disaster tolerance, filing, storage, heavily delete, VTL, cloud management function be in integrally.
2. form of backing up in realtime keeps completely the same with virtual disk VMDK form, and to Vmware, Hyper_v etc. is virtual
Changing platform, the open platform such as the KVM under openstack environment carries out data backup disaster tolerance protection.By without proxy backup, it is achieved
The quick backup of virtualized environment data and recovery, by there being proxy backup, it is achieved the accurately backup of virtualized environment data and
Fine granularity is recovered, and can recover single virtual machine, single file or single table space.
3. this method based on backup virtualization is when specified file system write data file, is automatically uploaded to
Cloud platform, as：Baidu's cloud, Kingsoft cloud.
4. possessing data de-duplication ability, data to back up can be split as several data blocks, to these by it
Data block carries out redundancy check, compares it with the data on Already in storage medium, for the data repeating only
Preserving portion, this mode can not only save the disk space of user greatly, also can shorten backup and the time recovered, maximum limit
The financial cost of the saving user of degree and time cost.
5. the various information of graphically managing, including the state of storage device and performance information, various number within a governance context
According to Protection parameters, the configuration information of various backup job, the execution state statistical information of various backup/restoration operation, backup plan
The monitoring of summary and backup job, daily record.
The technical scheme of this method is realized in：
Access 4 ESXI servers and backup virtualization device backup virtual equipment in lan network.
Use instant inserted and instant using type design, keep completely the same with virtual disk VMDK form, fast by calling backup VMDK
According to point, it is not necessary to increase any hardware such as independent backup server, media server, it is not required that at VM Ware virtual machine or
On other media servers of person, any program is installed, data backup work can be carried out.
When there is corrupted data, from storage medium, recover data.Set by backup virtualization device backup virtualization
Standby administration interface, recovers database data by web interface.
Both of which is had to virtual machine Backup and Restore：
The first pattern：It is directly returned to magnetic disk of virtual machine file VMDK in ESX by VMware ESX interface remote,
New virtual machine can be created recover, it is also possible to recover in original VMDK disk file.Backup virtualization equipment can be from any one
Individual snapshot point realizes that full virtual machine recovers.
The second pattern：Duplicate volume directly can be mounted on a physical server or in virtual machine, will backup
Volume becomes a local disk subregion.Can directly recover certain data directory of magnetic disk of virtual machine kind or database file.
Brief description
Fig. 1, a kind of flow chart based on backup virtualization
Detailed description of the invention
In order to make the purpose of the present invention, technical method is clearer, in conjunction with accompanying drawing, to the present invention further specifically
Bright.It should be appreciated that this method is only used for explaining the present invention, be not limited to the present invention.The technical scheme of this method is such reality
Existing：
Access 4 ESXI servers and backup virtualization device backup virtual equipment in lan network.
Use instant inserted and instant using type design, keep completely the same with virtual disk VMDK form, fast by calling backup VMDK
According to point, it is not necessary to increase any hardware such as independent backup server, media server, it is not required that at VM Ware virtual machine or
On other media servers of person, any program is installed, data backup work can be carried out.
When there is corrupted data, from storage medium, recover data.Set by backup virtualization device backup virtualization
