    Robocopy very slow, even if I do not copy anything and just create a list /L


    I want to create a backup with the "robocopy" command.I created a local directory with several junction points which all point to the different folders I want to backup and a network drive, which is a SMB share on the Internet cloud hosting provider.I use this command:robocopy D:\backup\ M:\ /COPYRobocopy very slow, even if I do not copy anything and just create a list /L :DAT /DCOPYRobocopy very slow, even if I do not copy anything and just create a list /L :DAT /MIR /COMPRESS /R:2 /W:1 /UNICODE /FFT /DST /UNILOGRobocopy very slow, even if I do not copy anything and just create a list /L :D:\backup.log /TEE /LThis does only list the files which would be synchronized. It takes more than 25 minutes. Doing the same sync with "TotalCommander" takes only 6 minutes. There are 212,142 files.Is this normal for robocopy? Or

    :)

    Robocopy vs Copy-paste

    Robocopy "D:\Folder" "H:\Folder" /L /Mir

    The above command lists thousands of files, including the ones not to be copied.
    Is there a command which lists only the ones to be copied, excluding the ones to be skipped?
    There is no need to view the skipped ones.

    Actually, that command won't list files that are not being copied BUT it lists all the directories that it traverses. To suppress that. simply tack on a /NDL (No Directory Listing).

    In the sample output below, note that the folder I am mirroring has 820 directories and 2708 files. The folders are already synced so not a single file or directory is displayed in the output.
