  • The easiest way to do a backup is to use the Windows Backup tool. It lets you choose individual files and folders and select your external hard drive as destination:

    Other alternative is to use robocopy /MIR command, so only the modified files since the last backup are copied:

    robocopy C:\MyData D:\MyBackup /MIR

  • If you would not like to delete files on the external disk which are no longer present on the local one, it seems ok. In other case, the /MIR should serve better than /copyall.

    I also suggest you to preview the changes before you really use the command - see the Logging options in the command-line help. For example /L switch to the preview mode which just lists the changes which would have been made, but still not touching anything.

  • The Windows 7 Backup and Restore feature does not fit you? You can manually select folders to backup on schedule.

    You can also study options of the xcopy command-line tool. For example, /D switch might help you.

  • Can I setup multiple backups with Windows Backup and Restore?.. at different locations and of different folders??? like, suppose, I have a huge chunk of photos.. AND... videos... AND... my work related files.

    NOW, i want all my Work related files to be in Drive1, Videos in Drive2, and photos in Drive3??? .. can i do that?

    AND, im afraid, robocopy is new to me, and i read abt it on wiki, sounds extremely helpful for me.. Can u please suggest me some link to read about it in detail? thanks. :)

  • No, Windows Backup and Restore supports only one backup plan, schedule and target location.

  • For Robocopy: will this work for my purpose? plz check:

    robocopy "source" "destination" /copyall /e

    ????

    OR will I have to add anything else at the end to get what I want, i.e, to only copy the changed and new files...??
