John,

     I'm not sure about the single image bit, I think it's unique for Stac.
     Veritas's backup product for mobiles (tele?something?) has the same
     feature but as I said it' made specifically for mobile backup/restore.

     What I do know is that besides TDP for W uses Stac technology, TDP for
     W will in the near future be able to backup to a *SM server. This has
     tha advantage of being able to do NT image backup's and thus a
     fast(er) NT disaster restore (BMR) thru the network.

     just some extra info.

     regards Walter Ridderhof.

Subject: Tivoli Data Protection for Workgroups vs. Stac Replica

  Do I understand correctly that Tivoli Data Protection for Workgroups is
designed to provide fast backup and recovery for Windows environments as
well as 'bare metal restore'?
  I am having a discussion with an associate about Stac Replica and 'bare
metal restore'. It seems that BMR is required here. It looks like the only
advantage Stac Replica might have is that it will retain only one copy of a
given file no matter how many images of that same file exist in the
environment. That is, if you and I both have the same file, DSMADMC.EXE on
our systems, the backup service will only keep one copy if they are in fact
the same.
  Is this feature available, coming or never going to be in TSM? Could Stac
Replica be used in conjunction with TSM to minimize network traffic? I am
thinking that Stac Replica could be used to 'filter' data in a small area
and use TSM to backup the Replica server? Any experience with this?
Pro's/Con's?

TIA
