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
