Hello everyone,
Can confirm this is a real concern.
I recently experienced massive data corruption with files stored in OneDrive, and assumed OneDrive was at fault. Opening one file often resulted in viewing a completely different file, or losing the ability to view the file altogether (presumably because the extension had been changed to the wrong filetype).
The source of the problem was installing a copy of OneDrive on each of my personal PCs, and a copy on my storage server with the intention of synching each instance together. The problem, as it turns out, was OneDrive being mapped to a pool on my server controlled by DrivePool.
Unfortunately, I have lost some files completely, as OneDrive proceeded to overwrite all of the synched copies as well as the online copy. Since they weren't deleted, they weren't placed in the OneDrive recycle bin.
Lesson Learned: Do not use any two-way synching service with Drivepool. I don't fully understand the mechanics of all of this, but I will only perform one-way syncs to my pool from now on.
Edit: I was fortunately, able to roll-back my OneDrive account to recover everything.
