A protection group can contain multiple Elastic Compute Service (ECS) instances. This allows you to use a plan to perform centralized operations on multiple ECS instances. If you use EBS async replication for disaster recovery, you must create a protection group. This topic describes how to create a protection group.
Prerequisites
vSwitch mappings and security group mappings are configured. For more information, see Step 3: Configure network and security settings.
Procedure
Log on to the Cloud Backup console.
In the left-side navigation pane, choose .
If you are not using EBS Async Replication, click Switch to EBS Async Replication.
On the Site Pairs tab, click the site pair, and then click the Protection Group tab.
On the Protection Group tab, click Create Protection Group.
ImportantBefore you create a protection group, you must create vSwitch mappings and security group mappings. For more information, see Step 3: Configure network and security settings.
In the Create Protection Group dialog box, configure the parameters and then click OK. The following table describes the parameters.
Parameter
Description
Name
The name of the protection group. Specify a recognizable name. The name must meet the following requirements:
The name must be 2 to 128 characters in length.
The name must start with a letter and cannot start with
http://orhttps://.The name can contain letters, digits, colons (:), underscores (_), and hyphens (-).
Expected RPO
Set the value to 15. Unit: minutes. The expected recovery point objective (RPO) of the protection group. An RPO is a time-based measurement of the maximum amount of data loss that is tolerable to a business system.
Zone of Production Site
The zone where the production site is deployed.
Zone of DR Site
The zone where the disaster recovery site is deployed.
After the protection group is created, you can find it on the Protection Group tab. The protection group is in the Initializing state.
What to do next
After you create a protection group, you can perform the following operations.
Operation | Description |
Manage Protected Instance | Add an instance to the protection group or remove an instance that no longer requires protection from the protection group. |
Enable Replication | After you add an instance to the protection group, click Enable Replication to replicate data from the protected instance to the disaster recovery site. |
Disable Replication | Stop replicating data to the disaster recovery site. |
Manage Protection Group | Modify or delete the protection group that contains no instance. After an instance is added to the protection group, you cannot modify the protection group information. |
Forward Protection |
|
Enable Reverse Replication | After the disaster recovery site takes over the business and the production site has recovered, replicate data from the disaster recovery site to the production site to prepare for the failback. |
Reverse Protection |
|
Clear Protection Group | You can delete a protection group if you no longer need it. |
Fault Drill | Start a fault drill for the protection group. Note You can perform a fault drill if the protection group is in the Replicating Incremental Data state or has a recovery point. For more information, see Fault drill. |
Delete Fault Drill Group | After the fault drill is complete, delete the fault drill group. |
