Tip to copy the directory tree under Windows XP Vista Seven I have 2 NAS at home (System and User) and a Mediacenter (video NAS). When I'm not (often) at home, I use my laptop and I always downloads new files or people give me a lot. Then I backup my NAS directories but never correspond with my backup software (SynBackPro) and I forget the name of directories and files stored on my NAS. I decided that the best way to manage my backups is to copy on the hard drive of my laptop the directory tree of my NAS without copying files. I tried using xcopy but I had known the problems of those old DOS commands (insufficient memory, directories not copied, slow ...) xcopy source target / I / T / E / Z The solution is robocopy (Robust File and Folder Copy => Standard Windows 7/Vista command) that is available in Seven / Vista and XP/2003 (XP Resource Kit). Here is my code to copy directories on my laptop. Creates \ _NAS \ directory.NAS on HD @echo off set NAS1=\\dns323 set HD=D: set arbre=_NAS set ext1=%NAS1:~2% for %%a in (old_system materiel system hotfix) do ( robocopy %NAS1%\%%a %HD%\%arbre%\%%a.%ext1% /S /E /CREATE /NP /LOG+:"%HD%\log.txt" /XF *.* /R:3 /W:1 /XA:RASHCNETO ) Fantastic, it works and in addition, there is a LOG file. I can now save files on my laptop and save them in the right directories of my NAS, then use my backup software.
