Restoring or retrieving data during a failover

When the client fails over to the secondary server, you can restore or retrieve replicated data from the secondary server.

Before you begin

Before you begin to restore or retrieve data during a failover:

Ensure that the client is configured for automated client failover.
Ensure that you are connected to an IBM Spectrum® Protect server that replicates client nodes. For more information about failover requirements, see Requirements for automated client failover.

Restriction: In failover mode, you cannot back up or archive data to the secondary server.

Procedure

To restore or retrieve data during a failover, complete the following steps:

Verify the replication status of the client data on the secondary server. The replication status indicates whether the most recent backup was replicated to the secondary server.
Restore or retrieve your data as you would normally do from the client GUI or from the command-line interface.
Tip: Restartable restore operations function as expected when you are connected to the secondary server. However, restore operations that are interrupted when the primary server goes down cannot be restarted after the client fails over. You must run the whole restore operation again after the client fails over to the secondary server.

Results

If the replicated data on the secondary server is not current, you are prompted to continue or to stop the restore or retrieve operation.

For example, to restore the build.sh directory at the command-line interface, you issue the following command: Mac OS X operating systems

dsmc res /build.sh

dsmc res C:\build.sh

The following output is displayed:

If you respond with N, the following message is displayed:

ANS1074W The operation was stopped by the user.

If you respond with Y, restore processing continues as normal, but the data that you restore might not be the most current.
