Abstract
The invention provides a method and a system for multi-node incremental backup. The method includes the following steps: a. systematacially detecting virtualized states and data, conducting once full data backup on a virtual machine after the detection; b. systematacially detecting whether the full backup data are available or not, if the full backup data are available, entering the step c; if not, returning to the step a; c. comparing present data with the full backup data, judging whether the data have incremental quantity or not, if the data have the incremental quantity, entering the step d; if not, entering the step e; d. conducting backup on data which have the incremental quantity, and saving a backup point at the last moment; and e. identifying current time, and turning a backup indicator to the full backup data. The method and the system for multi-node incremental backup can achieve backup of data without third party permission, conduct repeated backup aiming at one virtual machine, and meanwhile recover to any backup point of the backup. Meanwhile, the method and the system for multi-node incremental backup can conduct backup on incremental quantity of data nodes and are low in cost and easy to achieve.
Description
Technical field
The present invention relates to technical field of virtualization, relate in particular to a kind of method and system of multinode incremental backup.
Background technology
Server virtualization, desktop virtual and applying virtualization are three big Intel Virtualization Technologies in now computer virtualized.It also is an important technology of following cloud computing.At present, begun the popularization of virtualized technology at the industry-by-industry in the whole world, and in the IT industry, coming into one's own gradually.
Present virtual market is progressively the big department space that occupies IT market, is virtualized into the mainstream technology into the IT world, and virtual machine begins to replace physical machine to come operational system and application, for the terminal user provides desktop services and application service.In order to guarantee safety of data, the existing backup mode that is directed to virtual machine has the third party software backup mode, comprises normal backup and incremental backup.The virtual producer of industry carries backup functionality, only comprises the normal backup mode, and the cost that adopts the third party software backup mode needs to buy third party's permission than higher.The backup functionality that virtual producer carries can only satisfy the demand of normal backup, realizes that the effect of incremental backup is not clearly or very big restriction is arranged.
Summary of the invention
The object of the present invention is to provide a kind of method and system of multinode incremental backup, need not third party's permission, can realize backup data.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method of multinode incremental backup comprises step:
A: system detects virtualized state and data, detects the back that finishes virtual machine is carried out a complete data backup;
B: whether system detects above-mentioned complete Backup Data available, if available, enters step c; Otherwise, return step a;
C: current data and complete Backup Data are compared, and judgment data has or not increment, if having, enters steps d; Otherwise, enter step e;
D: back up for the data that incremental portion is arranged, and preserve last backup point constantly;
E: current time is identified, and will back up pointer and point to complete Backup Data.
Preferably, step a specifically comprises: system detects the integrality of running status, hard disc data and the system data that will carry out the virtual machine of multiple spot snapshot, scans by the data of detection pointer to virtual machine, checks the integrality of its data; After finishing, detection carries out a complete data backup to setting virtual machine; And with the total system file backup to this locality or far-end be in the data storage.
Preferably, complete Backup Data comprises configuration file and disk file data described in the step b.
A kind of multinode incremental backup system comprises: server, client, and server establishes a communications link by network and client;
Desktop integrated machine system unit, a plurality of virtual machine are installed on the server,
Virtual desktop and client operating system are installed on the client, storage unit is installed in the client operating system;
Server is used to provide virtual machine physics running environment;
Client is used for the terminal user and connects the use virtual desktop;
Virtual machine is used for providing the virtual desktop environment to the terminal user;
Desktop integrated machine system unit is used for arriving client with the virtual machine Backup Data and by Network Transmission, and the cell stores in the client operating system is arranged.
Preferably, on the described virtual machine application program unit, VME operating system are installed.
The embodiment of the invention compared with prior art, the method and system of multinode incremental backup provided by the invention need not third party permission, can realize the backup for data; And can repeatedly back up at a virtual machine, simultaneously can one return to any backup point of backup; Also can the increment of data node be backed up simultaneously, cost is low, realizes simple.
