Nextcloud client just deleted all of my files, why did it do this?

Submitted ⁨⁨1⁩ ⁨day⁩ ago⁩ by ⁨bpt11@sh.itjust.works⁩ to ⁨selfhosted@lemmy.world⁩

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

Wary reader, learn from my cautionary tale

I’m not sure what to learn exactly. I don’t get what went wrong or why…

  That you should keep backups :P

  My answer was from @EmoPolarbear@lemmy.ca, who said pointig two different services that can provide digital files to the same folder is never a good idea. Even though I turned off OneDrive which I thought would avoid anything going wrong, it was still pretty bad, so just don’t do it in the first place. Probably read their whole comment though to make sure you understand fully

    Can you put the relevant comment link in the OP?

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.

it is now a non issue

IMHO it’s still a big issue that might lead to data loss to someone else. The Windows client should be hardcoded to refuse syncing in onedrive folder.

Someone should reproduce this in a VM and open a GitHub issue
