I'm using RoboCopy to back up between two hard drives.
I have noticed that the log is highlighting files that its copied to the destination folder even though they haven't changed since the last back up?
The new copies of this file are appearing in the source and destination folders and the file names have been changed from a standard name e.g. ParkFields.....xls to PARKF~1.xls. The next time I run RoboCopy it creates another copy of the original file and create an incremental increase in the file name e.g. PARKF~2.xls
Please can someone help to explain why RoboCopy is doing this and what can be done??
