The content of the invention
The invention aims to ensure that the data after backup virtualization are not lost completely and fast quick-recovery.Virtual machine online backup, not traffic affecting normally run；The fast quick-recovery of virtual machine, can tackle the requirement to data safety under extreme case.
In order to reach the purpose of virtualization backup, the technical proposal of the invention is realized in this way：
Data backup software is installed and configured on each virtual server, then the target end equipment including tape library, VTL and hard disc library is backed up, whole process is with traditional data backup.The continuity of whole backup procedure can so be ensured, simplify data recovery, and specific application program can be backed up.If, can be with usually very easily by single file access pattern into virtual server using the backup software based on agency.If backed up whole virtual server system, need to recover whole system during that recovery, then by its carry under a path, not usually production environment, the then file of user again in recovery system.
Comprise the following steps that：
Data backup software is installed and configured on each virtual server first.
Secondly the target end equipment to disk array is backed up, it is ensured that the continuity of whole backup procedure.The copy of OS files, patch and application program can be reduced using data de-duplication technology, simplifies data recovery, and specific application program can be backed up.If, need to be by single file access pattern into virtual server using the backup software based on agency.If backed up whole virtual server system, need to recover whole system during recovery, after recovery by its carry under a path, not usually production environment, the then file of user again in recovery system.
Finally in standby virtual server, the medium of virtual server backup is with as traditional data backup.But, data retention over time will carefully confirm, it is not necessary that all preserve long time to all snapshots.Virtual snapshot is typically a new file, because it is full backup, without considering difference of the last time snapshot with current snapshot.Each snapshot can all use full backup window and use identical disk/tape space.The interior backup setting to virtual server is checked at a fixed time, it is ensured that all data can be backuped to, and normally data can be recovered.When recovering every time to some file or program, backup can be also verified accordingly.
Data de-duplication in said process, also referred to as single example storage, it is possible to reduce the memory space needed for backup.But data de-duplication can't shorten the time of backup, because data backup can just carry out data de-duplication after completing.
Brief description of the drawings
Fig. 1 one kind is based on virtualization redundancy technique scheme
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, once with reference to accompanying drawing, the present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
In order to reach the purpose of virtualization backup, the technical proposal of the invention is realized in this way：
Data backup software is installed and configured on each virtual server first.
