Restoring Data to a New DB Instance

Function

This API is used to restore data to a new DB instance.

Before calling an API, you need to understand the API in Authentication.

Constraints

The DB engine of the original DB instance must be the same as that of the target DB instance. For example, if the original DB instance is running MySQL, the target DB instance must also run MySQL.
The constraints on the original and target DB instances are as follows:
- For RDS for MySQL and RDS for PostgreSQL, the DB engine versions of the original and target DB instances must be the same.
- For RDS for SQL Server, the time zones of the original and target DB instances must be the same. Otherwise, data inconsistency may occur.
For RDS for MySQL and RDS for PostgreSQL, the total volume size of the target DB instance must be at least equal to that of the original DB instance.

**Table 8** restore_point field data structure description
Name	Mandatory	Type	Description
instance_id	Yes	String	Specifies the DB instance ID.
type	Yes	String	Specifies the restoration mode. Enumerated values include: backup: indicates restoration from backup files. In this mode, backup_id is mandatory when type is not mandatory. timestamp: indicates point-in-time restoration. In this mode, restore_time is mandatory when type is mandatory.
backup_id	No	String	Specifies the ID of the backup used to restore data. This parameter must be specified when the backup file is used for restoration. NOTICE: When type is not mandatory, backup_id is mandatory.
restore_time	No	Integer	Specifies the time point of data restoration in the UNIX timestamp. The unit is millisecond and the time zone is UTC. NOTICE: When type is mandatory, restore_time is mandatory.
database_name	No	Map<String, String>	This parameter applies only to Microsoft SQL Server databases. If this parameter is specified, you can restore all or specific databases and rename new databases. If this parameter is not specified, all databases are restored by default. You can enter multiple new database names and separate them with commas (,). The new database names can contain but cannot be the same as the original database names. Note the following when you are specifying new database names: New database names must be different from the original database names. If they are left blank, the original database names will be used for restoration by default. The case-sensitivity settings of the new databases are the same as those of the original databases. Make sure the new database names are unique. New database names must be different from any database names on the original DB instance. The total number of new databases cannot exceed the database quota specified by rds_databases_quota. New database names cannot contain the following fields (case-insensitive): rdsadmin, master, msdb, tempdb, model, and resource. New database names must consist of 1 to 64 characters, including only letters, digits, underscores (_), and hyphens (-). If you want to restore data to multiple new databases, separate them with commas (,). Example: "database_name":{"Original database name":"New database name"} Correct example: "database_name":{"A":"A,A1,A2","B":"B1,B2","C":""} Wrong example: "database_name":{"A":"A","B":"B1,B2","C":"B1,C1","D":"D1,d1"}, Error causes are as follows: The new database name (A) is the same as the original database name (A). The new database name (B1) is not unique. When the database name is case insensitive, the database names D1 and d1 conflict. CAUTION: Before the restoration, make sure that the size of the restored data does not exceed the purchased disk capacity.
