Embodiment 1
[0035] This embodiment provides a method for controlling database backup performance. The database generates a control process for controlling the backup during the backup process, and the control process includes a generation function for performing backup to generate backup piece data, and / Or an acquisition function for acquiring the backup piece data; the method for controlling database backup performance includes the following steps:
[0036] Create a data object with the same name as the backup piece data according to the name of the backup piece data generated by the generating function;
[0037] Creating a memory block for storing backup piece data, and returning the memory address of the memory block to the obtaining function;
[0038] Calling the acquiring function, acquiring the data block in the data object from the acquiring function, and filling it to the memory address of the memory block;
[0039] Send the data block at the memory address of the memory block to a media...
Embodiment 2
[0078] This embodiment provides a database backup performance control system 1, and the media management layer process runs the database backup performance control system. See figure 2 , Shown as a schematic diagram of the principle structure of a control system for database backup performance in an embodiment. Such as figure 2 As shown, the database backup performance control system 1 includes an initialization module 11, a first creation module 12, a second creation module 13, a processing module 14, a data sending module 15, a closing module 16, a judgment module 17, and an end module 18. .
[0079] The initialization module 11 is used to initialize the MML process.
[0080] The first creation module 12 connected to the initialization module 11 is configured to create a data object with the same name as the backup piece data according to the name of the backup piece data generated by the generating function (sbtbackup). Specifically, the first creation module 12 obtains the ...
