Restoring Data to a New DB Instance

Scenarios

GaussDB(for Cassandra) allows you to restore the existing backup to a new DB instance.

Procedure

  1. Log in to the GaussDB NoSQL console.
  2. Restore a DB instance from the backup.

    Method 1

    1. On the Instance Management page, click the target DB instance.
    2. On the Backups & Restorations page, locate the target backup and click Restore.

    Method 2

    On the Backup Management page, locate the target backup and click Restore.

  3. In the displayed dialog box, confirm the current instance details and restoration method and click OK.

    • The default API type and DB engine version are the same as those of the original instance and cannot be changed.
    • GaussDB NoSQL automatically calculates the minimum storage space required for restoration based on the size of the selected backup file. The storage space depends on the instance specifications, and must be a multiple of 10 GB.
    • You need to set a new administrator password.
    • To modify other parameters, see the description of creating DB instances of other DB engines in the Getting Started.

  4. View the restoration results.

    A new DB instance is created using the backup data. The status of the DB instance changes from Creating to Available.

    After the restoration, the system will perform a full backup.

    The new DB instance is independent from the original one.
