Thanks paul,

but the requirement is to upload to the backup server (from database
server),

"rsync -a --compare-dest=../$YESTERDAYS_BACKUP $TODAY $REMOTESOURCE
#change the src and dest"

this command does not seem to work for me !! I mean that the whole file is
getting transferred !

Any thoughts on this ?

Thanks again,
rssrik
