Restoring a Backup to a New Instance

Scenarios

You can restore an existing backup to a new GeminiDB Redis instance.

Usage Notes

• The new instance must contain at least as many nodes as the source instance.
• When you restore a backup to a new instance, the ACL account information of the source instance is not inherited.

Billing

This operation will create an instance and generate fees.

• Pay-per-use instances are billed based on how long they have been used. For details, see Pay-per-use Billing.
• Yearly/Monthly instances are billed based on your subscription period. For details, see Yearly/Monthly Billing.

   • The default API type and DB engine version are the same as those of the original instance and cannot be changed.
   • The new instance must have no less than nodes than the original instance.
   • GeminiDB automatically calculates the minimum storage space required for restoration based on the size of the selected backup file. The storage capacity depends on the instance specifications, and must be an integer.
   • You need to set a new administrator password.
   • You can adjust other parameters by following the parameter description in "Buying an Instance."

4. View the restoration results.

   A new instance is created using the backup data. The status of the new 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.

After the backup is restored to a new instance, you can release the source instance if it is no longer needed.
