Normally, clustered data is backed up by creating a backup plan on the management server (centralized backup plan). However, if you need to back up a specific data that is hosted entirely on a single cluster node, you can connect to this node directly and create a regular (local) backup plan. The drawback of this approach is that the backup task will fail if the data migrates to another cluster node or if the node becomes unavailable.
To configure backup of Exchange cluster data
Details. To access the Exchange cluster data, a domain user account that has administrative privileges on each of the cluster nodes is required.
When entering the name of an Active Directory user account, be sure to also specify the domain name (DOMAIN\Username or Username@domain).
In Data to back up, select one of the following:
In the catalog tree below Data to back up, select the Exchange cluster and specify data items to back up. The cluster databases or storage groups are displayed as single instances regardless of the number of copies they have within the cluster.
Naming the archive. Acronis Backup generates a common name for the new archive and displays it in the Name field. The name looks like [Application Instance Name]_Archive(N), where the [Application Instance Name] variable is a substitution for the Exchange server's or cluster's name, and N is a sequence number. If you are not satisfied with the automatically generated name, you can construct another name. Note that the use of the [Application Instance Name] variable at the beginning of the name is mandatory.
This mode is available for selection if Agent for Exchange is installed on each node of the cluster.
In this mode, the software will back up data from the active copy of the database or the storage group. If the active copy is not available at the moment, the backup will fail.
Backing up data from active copies may slow down the Exchange server performance, but the backed-up data will be in the most up-to-date state.
This mode is available for selection if Agent for Exchange is installed on each node of the cluster.
In this mode, the software will back up data from one of the available passive database or storage group replicas (if several). Also, specify what to do if all the passive copies are unavailable at the moment: either Back up active copy, or Fail the task.
Backing up passive copies does not affect the Exchange server performance and allows you to extend the backup window. However, passive copies may contain information that is not up-to-date, because such copies are often set to be updated asynchronously (lagged).
This mode is available for selection if all items selected for backup are hosted on a single node or if the console is directly connected to the agent.
In this mode, you specify the cluster node manually. Choose this mode only if you are absolutely sure that the data will not be relocated to another cluster node. If the data changes its location before or during the backup, the task will fail.
When entering the name of an Active Directory user account, be sure to also specify the domain name (DOMAIN\Username or Username@domain).
