Symptoms

Attempting to recover backed-up OneDrive files using the Web Restore console fails with the following error message:

Restore error... Unsupported file type..

Example of full error message:

"code": 99,

  "text": "ArchiveReader. Restore error. PC-LOURDES2020-5AFFA6CB-0184-4743-AAAC-35DBBFAD292D-F34590AC-E8D2-4CCB-928C-5639C5421E34A.tibx.  <- Unsupported file type.. Code = 0x40021 (module 4; code 33). Error occurred at c:/jenkins_agent/workspace/agents-archive-reader/1484/product/core/file/filesys/ntfs/ntfs_file.cpp:166 (InitializeData) Tag: 4b5d8963cbce44a6  $module = archive_reader_lxa64_1484"

 

Cause

The files being recovered are located in a local OneDrive folder on the user's PC. Because of this, the folder becomes an NTFS reparse point, which makes the recovery impossible.

Solution

To resolve the issue, disable the Files On-Demand option in OneDrive:

1. Make sure you are signed in to OneDrive.

2. Select the OneDrive cloud icon in the Windows taskbar notification area.

3. In the OneDrive window, click the gear icon in the top right-hand corner.

4. Select Settings from the drop-down menu.

5. In the Settings window, in the Sync and backup tab, click the Advanced settings link to expand the settings list, then disable the Files On-Demand option.
