create backup in 12c Grid Control

I create backups in grid control and use that backup to duplicate on another server. It always seems that I need prior archivelogs available to make it happen. This is the backup script that grid creates for me when doing a custom backup. Would  alter switch archivelog solve that. I can't try it till next week, when my scheduled clone happens, just want to be ready when it happens next week.

backup device type disk tag '%TAG' database;

backup device type disk tag '%TAG' archivelog all not backed up delete all input;

allocate channel for maintenance type disk;
