Database expansion method and database

Abstract

The embodiment of the invention provides a database expansion method and a database, the method comprises the following steps that: a control server applies a first cloud hard disk for a database instance; the database instance comprises a cloud host and a second cloud hard disk; the control server mounts the first cloud hard disk on the cloud host and copies data in the second cloud hard disk to the first cloud hard disk; the database comprises the control server used for applying expansion for the database instance, mounting the first cloud hard disk on the cloud host, and copying data in the database instance to the first cloud hard disk, the database instance used for storing and managing the data, and expanding according to the instruction of the control server, and the first cloud hard disk used for being mounted to the database instance, and expanding the database instance.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a database capacity expansion method and a database. Background technique [0002] The database is a warehouse that organizes, stores and manages data according to the data structure, which was born in the 1960s. With the rapid development of computer technology, communication technology and network technology in the past 50 years, the amount of data generated by enterprises and companies has exploded, making modern enterprises strongly rely on databases to save extremely important records. Therefore, database technology has also been rapidly developed and has become one of the most important supporting technologies in the information society. [0003] However, due to the rapid growth of the data volume of enterprises and companies, new requirements are constantly put forward for the capacity of the database. The capacity estimated during the establishment of the database will...

Therefore, the backup is more complicated and needs to be realized with the help of a special backup tool

[0008] In the above two methods of database expansion, the hard disk is a part of the server itself. Adding a hard disk or replacing a hard disk, or even directly replacing the server, all involve the original operating system, so the simple copy process cannot realize the expansion. Re-paste the data back to the new hard disk; only special backup software can be used for data backup and recovery

However, judging from the data storage capacity of general databases, it takes a long time to backup and restore data according to the above method, resulting in low efficiency.
