For years I've been asked by my customers if they could have many versions for 
files in their primary pools while limiting the versions in their copy pools to 
1 for disaster recovery.
   
  In reading up on the new TSM V5.4 feature "Active-Only Storage Pools" it 
looks like this is now a reality. I could create an Active-Only storage pool 
(limited to backup data, no archive data). This new pool would now become my 
new destination pool for my backup storage pool command.  I could even go one 
step further and choose to collocate this data by node. The end result would be 
a set of tapes at DR that would not have to skip over any files when performing 
a restore.
   
  I realize great consideration has to be done before implementating something 
like this because if the active file is corrupt you wouldn't be able to recover 
a previous version. Still, in the case of DR I know I have many customers that 
would accept the risk in order to reduce the amount of data they have offsite 
and to speed up their restores.
   
  I know that you can set a tape in an active only storage pool to offsite so 
I'm assuming that it will be included with move drm.  I still haven't completed 
testing myself yet though.
   
  I'm wondering if anyone out there is considering this as well?
