Performing a rollback for clusters and cluster nodes

A rollback is the process of restoring the volumes on a machine from recovery points. For a server
cluster, you perform a rollback at the node, or machine, level. This section provides guidelines for
performing a rollback for cluster volumes.

Performing a rollback for CCR (Exchange) and DAG clusters

To perform a rollback for SCC (Exchange, SQL) clusters:
1. Turn off all nodes except one.
2. Perform a rollback using the standard AppAssure procedure for the machine as described in
Performing A Rollback
3. After the rollback is finished, mount all databases from the cluster volumes.
4. Turn on all other nodes.
5. For Exchange, navigate to the Exchange Management Console, and, for each database, perform the
Update Database Copy operation.

Performing a rollback for SCC (Exchange, SQL) clusters

To perform a rollback for SCC (Exchange, SQL) clusters:
1. Turn off all nodes except one.
2. Perform a rollback using the standard AppAssure procedure for the machine as described in
Performing A Rollback
3. After the rollback is finished, mount all databases from the cluster volumes.
4. Turn on all other nodes one-by-one.
NOTE: You do not need to roll back the quorum disk. It can be regenerated automatically or by
using cluster service functionality.

Replicating cluster data

When you are replicating data for a cluster, you configure replication at the machine level for the
individual machines in that cluster. You can also configure replication to replicate the recovery points for
shared volumes. For example, if you have five agents that you want to replicate from source to target.

Removing a cluster from protection

To remove a cluster from protection:
1. Do one of the following:
• In the Core Console, click the Machines tab, and then select the cluster that you want to remove
• In the left navigation area, select the cluster that you want to remove to view the Summary tab.
2. Click the Actions drop-down menu, and then click Remove Machine.
3. Select one of the following options.
