im running win7
i have a folder on my computer with the files i want to backup, being "T:\my user files", the destination is the "V:\" drive
if i moved or delete a file in T:\my user files and execute the backup to destination drive of V:\ it copies the moved file again but it still leaves it in its old location (in the backup) and if a file is deleted it doesnt delete it from the backup
the /U switch is to only update files in that directory where i want to add new ones aswell and if the files moves it then wouldnt update it anyway..
XCOPY "T:\my user files" "V:\" /D /E /C /R /I /K /Y
looks like i will have to use one of those other ones you suggested
