Embodiment 1

[0035] An embodiment of the present invention provides a disaster recovery device, such as figure 1 As shown, the device includes a first information receiving unit 101, an information merging unit 102, and an information sending unit 103; wherein, the first information receiving unit 101 is used to acquire the operation information of the local file system; the information merging unit 102 is used to The operation information is combined; the information sending unit 103 is configured to send the combined operation information to the remote end.

[0036] In this embodiment, the operation information refers to the record of the user's operation on the file in the client, data server or metadata server in the local file system, which may include the operation on the file, operation time, file identification and other information. The operation on the file may include file creation, update, truncation, deletion, and addition of file content. The operation time refers to the tim...

Embodiment 2

[0046] An embodiment of the present invention provides a disaster recovery device, such as figure 2 As shown, the device includes a first information acquiring unit 101, an information merging unit 102, and an information sending unit 103, the functions of which are similar to those in Embodiment 1 and will not be repeated here.

[0047] In this example, if figure 2 As shown, the device further includes a storage unit 201, and the storage unit 201 is configured to store the acquired operation information. And the information combining unit 102 combines the stored operation information according to the preset time.

[0048] In this embodiment, the information combining unit 102 can combine the operation information according to the granularity of the file, and the last operation on the file shall prevail, that is, when more than one operation is performed on the same data area of ​​a file, the Combining the operation information according to the granularity of the files ref...

Embodiment 3

[0053] The embodiment of the present invention also provides a disaster recovery device, such as image 3 As shown, the device includes a second information receiving unit 301 and an operation execution unit 302; wherein, the second information receiving unit 301 is used to receive the operation information corresponding to the local file system; the operation execution unit 302 is used to execute the operation information in the operation information operation.

[0054] In this embodiment, the disaster recovery device is set on the side of the remote file system, and by receiving the operation information corresponding to the local file system, the data in the local file system can be backed up to the remote end; the operation execution unit 302 executes the The operation in the operation information can restore the data in the local file system, so as to achieve the purpose of disaster recovery.

[0055] In this embodiment, the hardware device of the remote file system does...

Abstract

The embodiment of the invention provides a disaster recovery method, a disaster recovery device and a disaster recovery system. The method comprises the following steps: acquiring operation information of a local file system; combining the operation information; and transmitting the combined operation information. The method can collect and combine the operation information of operations of a local user or server, and transmits the combined operation information to a remote server, so that the remote server performs corresponding operation synchronization according to the operation information to achieve the aim of remote backup.

Description

technical field [0001] The present invention relates to communication network technology, in particular to a disaster recovery method, device and system. Background technique [0002] Today, when information systems generally become the lifeblood of enterprise operations, business continuity can be ensured by building a remote disaster recovery mechanism. Among them, disaster recovery refers to protecting users' applications and data from failures and disasters to ensure continuous use. [0003] At present, there are online remote disaster recovery, such as host-based remote disaster recovery, through the data replication software installed on the server, or the data replication / disaster recovery tool provided by the application, using the TCP / IP network to connect to the remote backup server to asynchronously way to replicate data. However, the inventor found that the defects of this remote disaster recovery method are: in an environment with a large number of servers, th...
