What are the differences between default RDS backups and Data Disaster Recovery - ApsaraDB RDS

ApsaraDB RDS generates backups called default backups. When default backups do not meet your requirements, you can use Data Disaster Recovery to implement advanced backup features.

	Restore data to an RDS instance by using backup files	✔️	✔️	Restore data to a new instance Restore full data Restore individual databases and tables Restore data to the original instance Method 1: First restore data to a new instance, verify the data, and then migrate some or all databases and tables to the original instance. Method 2: Use the database and table restoration feature to restore full data to the original instance. Method 3: Use the logical backup created by Data Disaster Recovery to restore data to the original instance. Restore data to another existing instance Method 1: First restore data to a new instance, verify the data, and then migrate the data to another existing instance. Method 2: Use the logical backup created by Data Disaster Recovery to restore data to another existing instance. Restore data to a self-managed database Method 1: First restore data to a new instance, verify the data, and then migrate the data to a self-managed database. Method 2: Use the logical backup created by Data Disaster Recovery to restore data to a self-managed database. Method 3: First download backup files, and then restore the backup files to a self-managed database.
