You have some options:

  * Consider an offsite DD appliance and have "corporate" update their 
policy to require offsite backup, rather than tape backup.
    * Consider a DD "replication" software license (one needed for each 
appliance) to automatically copy your local DD data to the offsite 
machine.  Note, however, that the offsite copy is not known to NetBackup 
if the DD replication software does the copy (without OST).  DD or your 
VAR will be able to calculate the bandwidth you'll need between 
appliances (but don't trust them!).  DD wants $$$ for their replication 
license.
    * Without the replication license, consider a Vault license to copy 
the data from the local DD to offsite DD.  However, this may require 
significantly more network bandwidth.
    * Consider an OST license to go with your replication license, as it 
allows the DD appliances to replicate your NetBackup images, while 
NetBackup knows about both copies.  Both DD and Symantec want $$$ for 
the OST licenses.  Too bad. :-(
  * Consider a Vault license to copy NetBackup images from your DD 
appliance to your local tapes for trucking offsite.

IMHO, don't give more than a passing glance at advice to roll your own 
scripts to do the offsite copies; ... use the Vault option of NetBackup 
(or whatever the current licensing is that includes vault.

If yours is a multi-site company, consider using the DD appliance on 
another site, with them using yours are their offsite backup.

Don't consider VTL as a solution to your requirement to store backups 
offsite. It isn't a solution for that and will only complicate your 
life, IMHO.

Anyone have experience with the the performance improvement of OST?  
I've heard everything from "small" to "it's the only way to come close 
to the rated speed of a DD appliance".

Finally, you or someone mentioned "basic disk".  A NetBackup marketing 
manager recently told me that the only option for new licenses is the 
"per TB" method when stored on DataDomain.  I forget his name for the 
license, as I was too upset reading his "company bull":

    *The introduction of deduplication technology enables customer to
    retain data for significant periods of time on disk and is not
    consistent with the intended role of Basic Disk.*

Just makes you want to hug Symantec marketing management, doesn't it?
