Creating a Group for Migration Clients

You should create a group for your migration clients. The start time for this group determines when automatic premigration activities take place. When Backup backs up a group containing migration clients and save sets, premigration occurs for qualifying files. Premigration happens automatically and is not controlled by high and low water marks. For automatic premigration to occur, Backup requires that files be premigrated as part of a group.

Since premigration is a resource-intensive process, you should designate a start time for the group when other system demands are low. See "Backup Group Configuration " for details about how to configure Backup groups.
