Embodiment 1

[0031] Such as figure 2 As shown, it is a flow chart of the data remote backup method in Embodiment 1 of the present application, and its specific processing process is as follows:

[0032] Step 21, after the database server reaches the first specified time point or receives the local backup notification signaling, perform local backup of the data that needs to be remotely backed up;

[0033] The local backup notification signaling may be, but not limited to, sent to the database server by the backup server managing the database server.

[0034] The database server can perform data backup regularly, or perform data backup after receiving the local backup notification signaling. If the data backup is performed regularly, the database server will automatically perform local backup as long as it reaches the first specified time point. The first The specified time point can be periodic or aperiodic.

[0035] Step 22, the database server compresses the locally backed up data;

Embodiment 2

[0045] Based on the data remote backup method proposed in Embodiment 1 of the present application, Embodiment 2 of the present application provides a database server whose structure is as follows image 3 As shown, it includes a local backup notification signaling receiving unit 31, a local backup unit 32, a data compression processing unit 33, a backup data acquisition signaling receiving unit 34 and a data sending unit 35, wherein:

[0046] The local backup notification signaling receiving unit 31 is configured to receive the local backup notification signaling;

[0047] The local backup unit 32 is used to perform local backup of the data that needs to be remotely backed up when the first specified time point is reached or after the local backup notification signaling receiving unit 31 receives the local backup notification signaling locally;

[0048] The data compression processing unit 33 is used for compressing the data after the local backup after the local backup unit 3...

Embodiment 3

[0054] Such as Figure 4 As shown, it is a flow chart of the data remote backup method in Embodiment 3 of the present application, and its specific processing process is as follows:

[0055] Step 41, the backup server sends a local backup notification signaling to the database server it manages;

[0056] The specific steps for the backup server to send the local backup notification signaling to the database server it manages may be but not limited to the following:

[0057] When the backup server reaches the second specified time point, it determines the time period of the second specified time point, and then obtains the start time point of each database server managed by it to perform remote data backup, and determines among the obtained start time points After the start time point within the above time period, send a local backup notification signaling to the database server corresponding to the determined start time point, and obtain the start time point can be the start ...

Abstract

The invention discloses a remote data backup method, equipment and system. The method comprises the following steps: a database server locally backs up data to be remotely backed up after a first specified time point is reached or a local backup notice signal is received, compresses the data which is locally backed up and transmits the compressed data to a backup server managing the database server after receiving a backup data acquisition signal. By adopting the technical scheme provided by the invention, the problems of lower processing efficiency and higher consumption of transmission resources during remote data backup in the conventional remote data backup process are solved.

Description

technical field [0001] The present application relates to the technical field of data backup, in particular to a method, device and system for remote data backup. Background technique [0002] In the database system, the backup server is used to manage, schedule, and store the remote backup data of each database server. Each backup server is responsible for managing at least one database server. For example, backup server A is responsible for managing database server 1 and database server 2. The backup server A regularly backs up the data in database server 1 and database server 2 to itself remotely, usually in a serial manner, such as figure 1 As shown, the specific process is as follows: [0003] Step 11, the backup server A determines the databases in all databases of the database server 1 that need to perform remote data backup by searching the backup information list stored by itself, for example, the database server 1 includes database 1A and database 1B, and the back...
