Migration Overview

For security reasons, it is often necessary to hide the real IP address of your database. Migrating data through dedicated connections is an option, but it is expensive. DRS supports backup migration, which allows you to export data from your source database for backup and upload the backup files to OBS. Then, you can restore the backup files to the destination database to complete the migration. This method lets you migrate data without exposing your source databases to the Internet.

You can use backup migration when you want to migrate on-premises databases to the cloud.

Without connecting to your sources, DRS can help you complete data migration.
