Batch Help - Copying

Hi,

Hopefully you can all help.

I have been using the xcopy command for a while now to transfer over files using the appropriate switches. I now feel with my data storage growing that its time to up the anti a little and make this a more complete batch file.

What i basically do currently,

Copy certain folders across multiple drives across to a external HD over night using scheduled tasks.

What i want to do now however is every time i insert my external hd (currently set using computer management to Z:) automatically call a batch file to begin the copy process. Due to my collection growing i would like to only copy updated on new file in their specified directories rather than everything with an overwrite switch.

Hopefully someone will have the answer/solution to this.

Thanking in advanced,

Regards,

Steve.

More about batch copying
  1. You might like to have a look at the "robocopy" command (it's part of Vista and 7, but I think you need to get in from the Windows Resource Kit for XP). This is a far more intelligent and versatile copy tool than xcopy.
  2. You can create an autorun file to call your batch file and instead of using xcopy use robocopy. here are the list of switches for robocopy:

    Robocopy Options and Switches

    I have higlighted the one you need to use.
  3. if you want to use Xcopy then use the Autorun file on the root of the external drive as suggested by Lembi2001 and then to only copy new/modified files do the following

    In the souce dir use the attrib command to set the Archive attribute to all files "Attrib +a *.* /s"

    add the /m switch to your current xcopy command "xcopy c:\SOURCE-DIR\*.* X:\DEST-DIR\*.* /s/m

    The first time you run the command the whole folder will be backed up. from that point on only new/modified files will be copied.
  4. Hi,

    Sorry its taken so long to get back to you its been one busy week!

    Thanks for the kind replys, the robocopy idea seems the most sensible as i am currently on windows 7.

    For some reason i cannot seem to get this command to work in any way, shape or form.

    I have tried the following line,

    robocopy I:\data K:\robo

    Both of the above directory's exist. The one labelled I:\data contains files and the 'robo' directory does not.

    All i want to do is copy from one to the other? Even with switches added before and after the directory's i still cannot seem to copy.

    What am i doing wrong?

    Thanks again,

    Steve
  5. What output do you get from that command? (I've just tried it on my PC and it works as expected.)

    I used to use this as a way of replicating huge directories from one server to another and it was ideal for that purpose.
  6. C:\Users\Administrator>robocopy I:\data K:\robo

    Is there a log file i can look at to see why it has been skipped?
  7. I suspect that you only have directories immediately under I:\data. Use the /S switch to copy the subdirectories also (or /E to include empty ones). You might also look at the /R switch to handle open files.

    If that fails, try the /V, /X and /L to get more information.
