Cloud Backup:Before you begin

Last Updated:Jun 20, 2026

Cloud Backup can back up and restore an Oracle database on an ECS instance or an on-premises server. This topic describes the required preparations.

Step 1: Verify prerequisites and obtain credentials

  1. (For ECS instances only) Verify or install Cloud Assistant Agent.

    The Cloud Backup client requires Cloud Assistant Agent to be running on the ECS instance.

    • Instances created on or after December 1, 2017: The agent is pre-installed. No action is needed.

    • Instances created before December 1, 2017: You must install the agent manually. For instructions, see Install the Cloud Assistant agent.

  2. Obtain the username and password for the Oracle database.

    These credentials are used to log on to the Oracle database.

Step 2: Create a backup account and grant permissions

If you do not have a dedicated backup account, contact your administrator to create one. The backup account must have the sysdba role, and connect and resource permissions. The following steps show how to create a backup account named backupadmin.

  1. Log on to the Oracle database server and run the SQL*Plus tool as sysdba.

    sqlplus / as sysdba;
  2. Create a backup account named backupadmin.

    create user backupadmin identified by your_password;
  3. Grant the sysdba role to the backupadmin account.

    grant sysdba to backupadmin;
  4. Grant the connect and resource permissions to the backupadmin account.

    grant connect,resource to backupadmin identified by your_password;

    After completing these steps, use the new backup account's credentials to register the Oracle database instance. On the Register Oracle Database Instance page, in the Authentication section, turn on Use instance password authentication. Then, enter backupadmin for Database Username and the account's password for Password.
