Restoring files from an image-based backup or offline drives of a OneDrive folder can result in files appearing corrupted or inaccessible. This issue is often due to OneDrive's Files On-Demand feature, which stores placeholder files instead of the actual data locally. Additionally, even when files are fully downloaded, they may retain reparse point attributes that can prevent the files from opening correctly.
This problem can occur with image-based backup solutions or when restoring files from offline drives if the backup includes placeholders instead of the actual file data. The following software are examples of those which may be impacted.
- Acronis True Image or Cyber Protect
- Macrium Reflect
- Veeam Backup & Replication
