For a long time I’ve used OneDrive to sync all of my files and keep them safe, but I’ve been really getting into self hosting all my own services, so today I set up NextCloud to replace it. I told it to sync my OneDrive folder, and it did it’s best. It copied the file structure and had all the directories and everything but emptied every folder, it deleted every single file I had on my OneDrive, now all I have is empty folders.
Luckily OneDrive has a file recovery system where I can give it a time and date to revert back to so my data should all be safe, but why on earth did it do that in the first place? This was incredibly stressful and terrifying I thought I lost all my work. What did I do wrong?
Edit: I’ve identified the issue and have learned from this experience, it is now a non issue and was completely my own doing. Wary reader, learn from my cautionary tale
Because you pointed 2 programs at the same directory to sync the content with an external directory structure.
In my experience adding an already existing directory structure to a sync program is a bad idea. Create the directory and then move the existing structure into it to be safe or/and at the very least have a backup.
Not having a backup is on you. You got lucky this time.
