Dan,

Thanks for the comeback.......I think those conversations got mixed up with
the EMC SRDF feature which my customer happens to be a sacred user of. EDM
is supposedly to be used as Enterprise Data Manager providing
backup/recovery of files/partitions/disks (?? not sure which it is)  to a
backup copy on tape.

I will keep u in the picture. Sources remain protected though. I think u
will understand that.
