Duplication or Replication??

I have two sites. - LOCAL site has one NBU 7.6 Master/Media a Tape Library with two LTO6 Drives - REMOTE (DR) site has one NBU Master/Media a Tape Library with two LTO6 Drives NOTE: Local Site and...

    if you would like to setup the DR only with Tape Library , configuring both sites under one master server is the better option.

    make sure you have very good bandwith to duplicate the backups from one site to another site...

    take backups to local tape library  and use SLP to duplicate the data to remote tape library.

    yes..you can perform all backup restore opeatioins as same as you are doing now in one site...

    the biggest thing you need to consider is network connectivity and bandwidth.

    since you have tapes... all data has to duplicate over the wan, it can not do optimized duplications.( its for DD and MSDP)

What is the bandwidth between your two sites? And is it used only for backup or shared across your organization?

If you have DataDomain with replication to DR, I would suggest using SLP to create a copy from DR-DataDomain to your DR-TapeLibrary. Here how it will look in action:

Backup-To-DataDomain (Copy1) => Replicate-To-DR_DataDomain (Copy2 - Optimized duplication using WAN) => Duplicate-To-DR_TapeLibrary (Copy3 - created using Copy2)
