we are running robocopy script for backing up data from one server to other server.
It looks like it is doing full backup at scheduled time and it is taking very long time and not getting finished till work hours in morning.
The robocopy script is
robocopy "\\server1\share" \\server2\share /E /MIR /Z /R:5 /W:10 /NP /LOG:d:\robocopy\share_backup.log
Can anyone suggest what option should we use in script so that it runs differential backup rather than full backup every night.
Thanks in advance.
