Can I Encrypt the Disk After Purchasing a GaussDB Instance?

You can enable disk encryption when purchasing a GaussDB instance. For details, see Buying a DB Instance.

After an instance is created, the disk encryption status and the key cannot be changed.

If you want to configure disk encryption for a created instance, perform the following operations:

• Restore instance backup to a new instance and enable disk encryption for the new instance.
• Use the Data Replication Service (DRS) migration function to migrate instance data to other encrypted instances.
