In older articles I often wrote about Bare Metal Recovery, a feature included in Data Protector without any additional costs and called Enhanced Automated Disaster Recovery (EADR) – see https://www.data-protector.org/wordpress/?s=eadr. To recover the Cell Server (see link) I always told to use tape devices with a block size of 64K. With Data Protector 9.0X and Windows 2008 / Windows 2012 this is no longer required, the limitation is no longer listed in the Data Protector handbooks. Sebastian Köhler (see http://www.syncer.de) has tested EADR for a Cell Server with a higher block size. He made the tests with SAS / FC libraries, StoreOnce and file libraries. So, you no longer need separate tape drives to backup your Cell Server, this makes the administration more easier.
And an additional comment from Sebastian, the parameter -anyobj for the command omniiso is back and available with Data Protector 9.0X. For additional details, please review the article https://www.data-protector.org/wordpress/2014/04/eadr-cell-server-dp-8-1x-windows-2012-r2/.
