Problems solved by technology

[0008] In order to solve the deficiencies in the prior art, the present invention provides an index-based VMware virtual machine synthesis backup method, which solves the problem that the existing virtual machine synthesis backup method uses data content as the synthesis target, and the backup time is long and the efficiency is low. Flexible, does not support dynamic synthesis of arbitrary backup sets, cannot specify the problem of arbitrary backup set recovery

Embodiment Construction

[0037] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0038] An index-based synthetic backup method for a VMware virtual machine, the steps comprising:

[0039]Step 1, establish an index database through existing database technology, carry out full backup to the VMware virtual machine, and write the full backup information into the index database;

[0040] Said step one, the specific complete backup steps include:

[0041] 1) Use an application programming interface (hereinafter referred to as vSphere API) provided by VMware vSphere to establish a connection with the VMware virtual machine, and back up the configuration information of the virtual machine;

[0042] 2) Use the vSphere API to create snapshots, often creating Quiseced snapshots to ensure application or file system consistency; ...

Abstract

The invention discloses an index-based VMware virtual machine synthetic backup method. The method comprises the steps of establishing an index database, performing complete backup on a VMware virtualmachine, and writing complete backup information in the index database; performing incremental backup on the VMware virtual machine, and writing incremental backup information in the index database; in the index database, querying a latest backup index table, obtaining each latest sector block index record according to a backup time point, and storing the index records in a new synthetic backup index table; and querying the index database, obtaining a latest index record before a specified time point of each sector block, obtaining the position of each sector block in a storage medium backup set, reading contents of the sector blocks in the corresponding backup set, and writing the contents of the sector blocks in the corresponding positions of a virtual machine disk again, thereby finishing restoration. The efficiency is high and the consumed time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of computer data backup, in particular to an index-based synthetic backup method for a VMware virtual machine. Background technique [0002] Virtualization products are widely favored by customers. At present, virtualization products are widely used in fields with large data volumes such as finance, Internet, and medical care. VMware virtual machines have become the most used in the world due to their ease of use, rich functions, and high reliability. Wide range of virtual machines. [0003] Although VMware has a powerful virtualization function, in practical applications, if the hard disk is damaged or the hard disk file of the virtual machine is damaged, the VMware virtual machine cannot run normally, causing heavy losses to customers. Therefore, in view of the above situations, it is necessary to VMware virtual machine hard disk files for backup. [0004] At present, VMware backup mainly obtains the cha...
