Restoring a Backup

Prerequisites

• You have created a backup for an enhanced Hyperledger Fabric instance.
• You have unsubscribed from or deleted the enhanced Hyperledger Fabric instance.

Creating a Restoration Task

1. Log in to the BCS console.
2. In the navigation pane, click Restoration Management.
3. Click Create Restoration Task.

   

4. Configure task parameters.

   

   Table 1 Task parameters

   Parameter	Description
   Task	Name of a restoration task. Enter 4 to 24 characters. Only letters, digits, and hyphens (-) are allowed. Do not start with a hyphen (-).
   Source BCS Instance	The BCS instance to be restored
   Backup	The instance backup to be restored
   Billing Mode	This is set by default based on the billing mode of the selected BCS instance.
   Cluster	The cluster where the BCS instance will be deployed. You can use an existing cluster or create a new one. NOTE: CCE clusters of v1.19 or earlier are supported. If the BCS instance uses Fabric v1.4, the CCE cluster must be v1.15 or earlier. The memory usage of instantiated containers varies depending on the chaincode language. On each peer, a Go chaincode container takes up 10 MB for running, and a Java chaincode takes up 110 MB. For example, if 100 Java chaincodes need to be instantiated, a 16 vCPUs and 32 GB CCE node is preferred.
   Required Duration	This is required if Billing Mode is set to Yearly/Monthly.

5. Click Create Restoration Task.
6. On the payment page, confirm the order amount, and make the payment. Then return to the BCS console to view the instance that is being created.
   

   If a restoration task is finished, the BCS instance configuration and block data are restored.

Deleting a Restoration Task

1. Log in to the BCS console.
2. In the navigation pane, click Restoration Management, then click Delete in the Operation column of a restoration task.

   

3. Click Yes.
