I have a BE 12.5 box with a LTO2 Autoloader (HP StorageWorks 1/8 G2 Autoloader)and at least 3 Terabytes worth of Disk-to-Disk storage.  We are exploring Disaster/Recovery options where we would like to duplicate our LTO tape sets to another LTO Library (Dell PowerVault 132T 22 Tapes) at another site in case of a disaster.  I have the extra BE server all setup and functioning.  I am trying to figure out on how this setup would work.  I presume I would have to purchase an additional agent or some sort.  Any help would be appreciated.  Thanks
