Hi Les:
Trust you to always come up with an interesting suggestion or two. I
will have a further look at this but, on first blush, I do not think
that this will be very effective in our environment. We will be backing
up several small databases 1-8 GB each along with the related programs
from our development system, out users home directories which include
their Outlook PST files, Word/Excel files, etc. While the compression
should work for all files I can not see the dedup working for much
beyond the Word/Excel files. We will definitely have a look at it.
Thanks for you suggestion.
Regards, Hugh
