However I have yet to find OneDrive documentation stating this is the case.

** Files with neither of 'Always Keep On Device' nor 'Free Up Space', - In these cases the files are mainly on the machine (not in all cases), but I presume OneDrive decides when to free up space, and not store locally unless required, and when required, the 'Files On Demand' feature will be utilised and retrieve the file.

** 'Free Up Space' - These files by default appear only in the Cloud.** 'Always Keep On Device' - These files will always be on the machine.- The files within the machine's OneDrive folder are a mixture of files, set to:.Attempted recovery of a file from a backup resulted in a zero sized file in the recovery location.All files which were in the machine's OneDrive Folder were all present in the Acronis True Image backup.There was no exclusions for OneDrive in the 'Exclusions' tab of the TrueImage backups.The machine's OneDrive settings is/was set to allow for 'Files on Demand'.There seems to be a long history of backup issues with respect to OneDrive folders, and various workarounds and potential solutions. Ī general high level comment would be Acronis should from the outset warn users if it discovers OneDrive on partition/disk and inform the user that these files will not be correctly backed up. I am a relatively new user of TrueImage (less than 12 months), and I discovered the same issue only when attempting restore from a TrueImage backup an older version of a file (a file that had been located under a OneDrive folder).

Hi, just a few (rather very long) notes from my experience, as I discovered the same issue, in that files on OneDrive were not being backed up TrueImage, however they initially appeared to being backed up.
