What Are the Differences Between All, Tables, and Databases During DRS Object Selection?
You can select objects for DRS real-time migration and synchronization tasks. Real-time DR is performed by instance and does not support the selection of specified databases or tables.
During real-time migration, you can select All, Tables, or Databases for the migration objects.
During real-time synchronization, you can select Tables or Databases for the synchronization objects.
- All: This option is available only for real-time migration tasks. All objects in the source database are migrated to the destination database. After the migration, the object names will remain the same as those in the source database and cannot be modified.
- Tables: The selected table-level objects will be migrated or synchronized. New tables in the source database are not automatically added to the migration or synchronization objects. For a synchronization task, you can edit the synchronization objects to add new tables. Migration objects cannot be edited after the migration task is started.
- Databases: The selected database-level objects will be migrated or synchronized. Tables cannot be selected separately. New tables in the selected database will be automatically added to the migration or synchronization objects.
