User Case

"Setting up a new cloud-sharing environment involves syncing a data set from a mapped drive to OneDrive. To avoid moving the entire mapped drive into the OneDrive folder, I explored using the mklink function to join a directory to a folder within OneDrive. However, after testing, there seem to be sync issues when the data set remains on its current drive with the junction target set to the OneDrive folder:

  • Some changes in the mapped drive folders cannot be synced to OneDrive folders.
  • Folders cannot be saved on the mapped drive individually but like a shortcut of the OneDrive folders."

If you encounter the same issues above, you may try another 2 automatic workarounds in this post to sync network drive OneDrive by MultCloud or AOMEI Backupper. You may find them more suitable for your needs.

How to Sync Network Drive with OneDrive via MultCloud

An automatic task is always better than a manual task especially if you have many files to sync from a network drive to OneDrive. If you use a NAS device as your network drive, here comes the best sync solution - using MultCloud Cloud Sync. MultCloud, a professional cloud management service, allows you to manage your network drive and OneDrive files in one place. The Cloud Sync function is designed for cloud-to-cloud sync. It can help create an automatic sync task and then transfer files between NAS and OneDrive with 10 customizable sync modes.

  • Normal Sync: Just transfer files from one cloud to another cloud once.
  • One-way Sync: Sync from the source cloud to the target cloud without going back.
  • Real Time Sync: Constantly sync files from one cloud to another in real time.
  • Two-way Sync: The sync process will go both ways between the source and target.
  • Update Sync: The sync task aims to save the newest file version in the target cloud.
  • Mirror Sync: Always keep files the same in both the source and target by syncing.
  • Move Sync: Move the files and then delete them in the source after syncing.
  • Incremental Sync: Only sync the modified or added files to the target.
  • Cumulative Sync: The sync task will not sync the deletion to the target.
  • Full Backup Sync: All the files will be synced to the target each time.
