Are you aware of any plans for a future release of the BA client to take 
advantage of this?
Obviously a concern is restoring rehydrated data and the disk space 
requirements needed to do it on a large scale.

Thanks again.....

Hi Rick,

You can use the backup-archive client to back up files on volumes that are 
deduplicated by Windows. The files are backed up in their rehydrated
(non-deduplicated) state. (Note: The files are not rehydrated on the volume, 
but the rehydration occurs transparently as the file is read by TSM for backup.)

During restore, the volume will need to have enough space to contain the 
non-deduplicated files until Windows can re-deduplicate them.

TSM 6.4 client users will want to make sure they have the fix for IC92388
(6.4.1 or later) installed. This APAR does not occur in 7.1.

Best regards,

- Andy
