  1. Once saved, from the next backup run, inSync will no longer scan the folder path that you have mentioned in the above Global Exclusion section.

❗ Important

  1. Files On-Demand - was introduced by Microsoft to save disk space on the user devices, such that the files are physically present in the OneDrive cloud and not on the disk.

  2. By disabling this feature, the files from OneDrive will also be present on the user’s device physically.

  3. Although this will allow inSync to back up the files from the OneDrive folder, it will also lead to high disk usage by OneDrive files on the user’s machine.
