      @JaredBusch said in Windows 10 Junciton on UNC path:

      When trying to use a /J I get this error.

      C:\>mklink /J C:\Backup \\server01\share\Backup
      Local volumes are required to complete the operation.
      

      Map \\server01\share\Backup to a Z: and then mklink /J C:\Backup Z:\Backup?

          If you're trying to link a path to a drive, I think that subst might work or even psubst. I haven't used it in years.

            I know for a fact that I used mklink years ago when I set this up. Just apparently, I did something else also.

                That results in: Local NTFS volumes are required to complete the operation.

                Using UNC or mapped drive letter.

                Found an old post on here, and I used /D in that example.

                  When using /D, Windows works as expected, but Crashplan shows it as a 0 byte file.

                    My hunch is that your symlinks are not fully enabled.

                    Run this on the both sides (your computer running crashplan, and also the server you want your backups to reside on)

                    fsutil behavior query SymlinkEvaluation
                    

                    You will likely find this:
                    Local to local symbolic links are enabled.
                    Local to remote symbolic links are enabled.
                    Remote to local symbolic links are disabled.
                    Remote to remote symbolic links are disabled.

                    The "remote to" are your problem.

                    Run this to enable them:

                    fsutil behavior set SymlinkEvaluation R2R:1
                    

                    The quick way through is to just run this on both, but you may wish to run it on your workstation and try the backup, and then run it on your server is it still doesn't work.

                    If this is a complete failure, I apologize 😉

                    Edit: R2L at the other end....

                      Why isn't "Remote to" not enabled by default? Security?

                        No difference, but seriously good idea to check. Thanks.

                          Yes, I can copy the files to the local machine and let the backup take it from there. But I never had to previously. It, the script to copy the files, would just be one more point of failure.

                            You can use BareMetal VHD loader to mount a vhd/vhdx on a network drive at startup, and Crashplan will see that as a local drive. link

                              Is Crashplan running as a particular user?

                              If it's running as "System", it won't see the junction, will it?

                                Ok, so junction points don't support mapping to network path, symlinks do, and hardlinks can only be created for files, not folders. Try creating symlink and then create junction to the symlink and see if Crashplan can be fooled that way. So mklink /D C:\fake-Backup \\server01\Share\Subfolder and mklink /J c:\backup c:\fake-backup .
