This topic describes the data sources supported by Database Backup (DBS). Data source categories can include files as well as databases such as MySQL, SQL Server, PostgreSQL, Oracle, MongoDB, and Redis. Supported databases include Alibaba Cloud databases, self-managed databases, and databases of third-party cloud service providers.

Data sources are databases or file paths to be backed up. The data source information includes data source names, regions where data sources are located, database engines, and database accounts and passwords.

You can use one of the following methods to add data sources:
