2. On the High Availability page, select a failover server and click Cleanup Replication
3. Click OK when prompted to proceed with the cleanup.
4. Repeat step 2 and 3 for each failover server.
If you are on a version of DSM that is v6.2 or higher, see "Upgrading an HA Cluster" on page142.

Backup current DSM configuration
A wrapper key is required to create a system level backup of the DSM.
1. Log on to the Management Console as a System/All Administrator.
2. Select System > Wrapper Keys from the menu bar.
3. On the Wrapper Keys page, select Operation > Create, then click Apply to create the wrapper key.
4. You will see a confirmation message stating that the key exists. The same confirmation message is also
displayed on the Manual Backup and Restore page with a message saying that you can proceed with creating
a backup.
You must export this wrapper key in order to use it,
1. Select Export from the Operation menu to export key shares.
2. Set a number for both the Minimum Custodians Needed and the Total Number of Custodians. This setting
splits the wrapper key value among multiple custodians.

Minimum value required for Minimum Custodians Needed: 2
o
Maximum value required for Minimum Custodians Needed: 10
o
Minimum value required for Total Number of Custodians: 3
o
Maximum value required for Total Number of Custodians: 10
3. Select the check box next to the DSM administrators who will serve as custodians for the wrapper key shares.
Administrators of type System Administrator and All are listed. Any of these administrators, with the exception of
the default initial log-on administrator admin, can be selected as a custodian.
If more than one custodian has been selected, each of them is given a share of the wrapper key. The wrapper key
share is displayed on their Dashboard page when they log into the Management Console. Each administrator
must see a unique wrapper key share displayed on the dashboard beneath the fingerprint for the CA.
4. Click Apply on the bottom right hand corner. The generated wrapper key or key shares are exported and is visible
on the Dashboard, beneath the fingerprint for the CA. The Wrapper Key Share displayed in the Dashboard
window is a toggle. Click Show to display the wrapper key share value. Click Wrapper Key Share value to
display the string Show.
