Acronis has issued KB6132 dealing with this issue. Unfortunately it is a workaround rather than a solution. 

"Solution

To resolve the issue, do the following:

  1. In OneDrive Settings disable the option Save space and download files as you use them
  2. Wait until all files in OneDrive are syncronized to the computer. Note that synchronization may take considerable time if there are many files to process.
  3. Create a new backup task and run the backup. You can also continue to use existing backup task but please be aware that recovery from old backup slices will not be possible."

I would not call this a solution, it is a workaround that assumes you device has sufficient storage to store all files. My ancient HP Windows Table (has Window 10 Home on it but not latest build) would not have sufficient storage to do this. Also the second sentence of point 3 is unclear - can you do a disk restore, I cannot see why not. However trying to do a file recovery may be a different matter.

From doing some Google searching, this issue looks to be the way that reparse points are handled in backup software, i.e. whether they are treated as symbolic links or not?  This issue looks to have been introduced back in the Fall Creators Update #1709 and perhaps tightened up with the latest Spring Creators Update #1803.

Some suggestions that appear to have worked for some users include:

  • Omitting / excluding the OneDrive folders from Cloud backups (not likely to be popular given why users want to protect these folders / contents in the first place!).
  • Moving the OneDrive folder to a different location then back again, followed by making a new backup task?
  • Moving the OneDrive folder to a FAT32 filesystem that does not support the new reparse points (then back to the original location again).
  • Stop using the OneDrive Files on Demand feature and allow all files to return to the local drive location.  Again unlikely to be popular given why users want to use Files on Demand to reduce or maximise space on their local drives.

I suspect that the longer term answer is to wait for Acronis to produce an Update that fixes this issue by handling the new reparse points correctly.  Note: reparse points are not new in themselves as have been around since Windows 2000 was introduced.  The issue looks to be in the processing of these reparse points where they may be 'protected' by the owning application.

Steve, many thanks for providing this information. My preliminary testing indicates that the suggested work-around does not work for me.

Update I can confirm that it is not working for me. Not impressed!

Ian, just hit this one on my Insiders build of Win 10 where MS decided that I should use the OneDrive Files on Demand feature without my agreement!

I was testing another issue and using my OneDrive folder as source and got this exact problem - turned off Files on Demand, waited for all files to synchronise back to the local folder, then re-ran the OneDrive backup task and all worked fine!

Log examples: (starting with the failed backup with Files on Demand enabled).

Hi Steve, as far as I can work out I have the correct settings for OneDrive (see above). There is no corresponding setting for OneDrive for Business (which I discovered yesterday had not been properly installed on either of the systems on which I was having problems.

The error messages you provide are different to the ones I am getting (for cloud backup).

You will notice that it restarts the process three times before apparently aborting. I will check to see if there is a completed backup or nothing happened

Ran backup to local HDD. At first I thought it had not worked, but it seems to have done so:

Not sure what to conclude from this - works locally but not to the cloud.

Ian, this issue looks to mainly affect Cloud or network based backup tasks more than local drive ones from what I have read.

One observation, I have never allowed OneDrive (or Dropbox, Box etc) to store its files as sub-folders of C:/Users[myuseraccount]/ - I have always put these folders into the root of another partition, so my backup tasks show the Source as being From: E:\OneDrive\

Steve, as I do not use OneDrive I have not bothered to shift the location. In the past I have relocated DropBox but for some reason I did not do so when I did my last system rebuild. I have not checked to see if there is an issue when backing up to NAS. The system I am using at the moment is not backed up to the NAS as local + cloud has been sufficient. There is very little data on the system that is not also on my main system.

Hello

I had the same problem with Win10 ver 1803 and ATI. I solved the problem on a PC and a Laptop. I uninstalled Microsoft OneDrive for Business and then reinstalled it. The backup with ATI is perfect again ?
