PrerequisiteSame-Site Restoration
Before attempting to restore a backup, make sure you meet the following prerequisites for same-site restoration:
- The VantageCloud Enterprise site must be set up with Query Service and is configured for self-service support. If not available, raise a change request.
- You must be a Console administrator (have TD-CUSTOMER-ADMIN role) to create partial backups or restore backup jobs.
- Make sure the Console user exists in the database. Use Teradata username field on the User Settings tab of the Your account page. If the user does not exist, create one and grant permissions using the following commands respectively:
- CREATE <username> as password=<password>, perm=<desired perm space>;
- GRANT LOGON ON ALL TO <username> WITH NULL PASSWORD
- You have restore access rights on all databases and all tables on the system. This is to view all the objects in a backup. Use the following commands to grant privileges.
- DIAGNOSTIC ALLOWDUMPRESTOREALL ON FOR SESSION;
- GRANT DUMP, RESTORE ON "ALL" TO <td-username>;
- Grant create, alter, and drop permissions to the user.
You should have the database credentials of the user, that is, <td-username> and its <password>. Make sure the <td-username> has drop/create/alter permissions on the target database to restore data to the target system. For example, to restore data to a database named dbcmngr on the target system, use the following command to give drop/create/alter permissions.
- GRANT all on "dbcmngr" to <td-username>;
For Cross-Site restoration, in addition to meeting the prerequisites of same-site restoration on the source site, you must also fulfill the following:
- You must have Vantage 2.4.2 on both source and target sites.
- Make sure the Console user exists on the target site. If the user does not exist, create a user using the steps mentioned in the same-site restoration prerequisites.
- Grant create, alter, and drop permissions to the user on the target site.
- The logged in user must have restore access rights on all databases and all tables on the target site.
