A consistency group is a collection of discovered applications from the same host. Create a consistency group to back up application data of all member applications together to preserve consistency of data across the member applications. You apply a common policy to the members of a consistency group.
Use these instructions to access consistency groups:
Click App Manager and select Applications from the drop-down menu.
The Applications page opens.
From the left panel, select Consistency Group.
The backup/recovery appliance provides a consistent application data capture that undergoes snapshotting at the same moment in time for Windows applications on the same host, including SQL Server, and local file systems.
For all other configurations, a consistency group can be defined and an image of its member applications run as one job on the host but snapshots of each application is independent and not from the same point in time.
When creating a snapshot of these applications, the backup/recovery appliance resolves all of the applications into a collection of volumes.
Consistency groups are managed in the same way that applications are managed.
Create a consistency group
A consistency group is a group of applications on the same host that are quiesced and captured together using a single policy. As the name implies, consistency groups ensure consistent point-in-time capture and recovery across multiple applications. Capturing application data with a consistency group consumes fewer system resources than capturing applications individually. For this reason, it is common to see groups of SQL server databases placed into consistency groups.
Use these instructions to create a Consistency Group from the App Manager page:
Click App Manager and select Applications from the drop-down menu.
The Applications page opens.
Select one or more applications.
Right-click and select Add to Consistency Group from the drop-down list. The Add/Create Consistency Group dialog opens. By default, the Add to Consistency Group option is selected.
Click Create Consistency Group.
In Group Name, enter a name for the Consistency Group.
In Description, optionally add a brief description about the group.
Click Create.
Once the Consistency Group is created, a success message opens.
To protect the Consistency Group, click the Click here to manage group option. Otherwise, click Okay to close the success message.
Best practices for protecting consistency groups
All applications in a consistency group must exist on the same application server. You cannot place applications from different servers into the same consistency group.
A consistency group cannot contain multiple Oracle databases. However, a single Oracle database can be included in a consistency group with other applications.
Add applications to a consistency group
Use these instructions to add applications to an existing consistency group:
Click App Manager and select Applications from the drop-down menu.
The Applications page opens.
Select one or more applications you want to add to the consistency group.
Right-click and select Add to Consistency Group from the drop-down list.
The Add/Create Consistency Group dialog opens. By default, the Add to Consistency Group option is selected.
Select the group and click Add to add the selected applications to an existing group.
Once the applications are added, a success message opens.
Click Click here to manage group to protect the applications added. Otherwise, click Okay to close the success message.
Edit a consistency group
Use these instructions to edit an existing consistency group:
Click App Manager and select Applications from the drop-down menu.
The Applications page opens.
Click Consistency Groups in the left panel to access the Consistency Groups list.
Select the consistency group you want to edit and then select Edit from the drop-down list.
Make the necessary modifications to the consistency group from the Create Consistency Group window. These modifications are described in Create a consistency group.
Remove an application from a consistency group
Use these instructions to remove an application from a consistency group:
Click App Manager and select Applications from the drop-down menu.
The Applications page opens.
Select the applications you want to remove.
Right-click and select Remove from Consistency Group from the drop-down list.
The applications are removed from the group.
Delete a consistency group
Use these instructions to delete an existing consistency group:
Click App Manager and select Applications from the drop-down menu.
The Applications page opens.
Select Consistency Groups in the left panel to see the Consistency Groups list.
Select the consistency group you want to delete and then select Delete from the drop-down list.
Click Confirm in the confirmation dialog. The group appears as an orphan in the Applications window if there are any active images corresponding to that application.
