EMcopy issues

Hi

We are runing into some issues while migrating  Windows file servers

When we copy the data the last access time stamp is lost.We need that info because we are going to use rainfinity to archive and access time is one of the params we would like to key on 

We get the following errors during our copies.

Unable to set the directory \\\ time stamp
Error (5): Access is denied

We are going to migrate close to 100 hundred file systems and we are not feeling that emcopy is the tool for so many file systems with these 2 issues any ideas?
