Hi Alex, great question! Any files that are UNsync’d will not be effected, as odrive uses “placeholders” and is not a fully mounted virtual drive. Files that are currently sync’d will indeed fall victim to the encryption as they are open to manipulation, and will reflect any local changes to the cloud. Luckily, most of better cloud storage services have file versioning which would allow you to roll back to a pre-encrypted state. Please check the details of any cloud service you use to see if they support versioning.
