Based on the information posted you looked to only do the DR work as needed, and initiate same by transporting the tapes to the alternate site.
The function for this is the normal phase1/phase2 style of image importation at the alternate at such time as you have a need to make use of the backups on the tape. Under these circumstances your alternate site is unaffected until such time as you are doing the actual DR work. Note that this will cause a time stand-off until the data has been completely imported to the alternate site.
And, as noted by others, you can make use of automated image replication (AIR) to do the data transfer automatically from the primary site to the alternate site. The backup images are copied to the alternate DR site as part of the normal workload of the Master Server. Te data becomes resident at the alternate DR site almost immediately. It becomes completely local to it. Even the BMR data is copied over to the site and the BMR clients are automatically registered there. The easy advantage to the AIR soluitio is that you will have backup image data available to both sites at the same time and can perform data recovery independent of each other. Using the default action, only the site with the tapes can do that.
