My phone's storage has filled up, so I opted to use Google Photo's option to delete local files from the device. I've had Sync setup on my phone with the built-in Camera backup to my Linux server. However, when Photos deleted the local files, Sync deleted them from the server as well! From what I read in the documentation, this shouldn't happen, nor did it happen when I tested deleting some photos on the phone ahead of time. This isn't quite catastrophic, as I keep versioned backups of my camera folder, but it's pretty bad. Why did Sync do this? How can I prevent it from doing it again in the future?
edit- to expand on this, sync moved all of the files to "/srv/sync/camera/.sync/Archive/Camera". It's been caught by my other backup (Crashplan), but this is pretty bad.
edit 2- Ah crap, now I see that the share on my server had "Overwrite any changed files" checked. Am I correct in understanding that this is what the problem was? I tried to copy a file back into the sync directory on the server. When that option is checked, Sync instantly deletes it. When it's unchecked, it seems to leave it alone. So I should be able to just move all of the files in .sync/Archive back into my normal directory on the server, and Sync will leave them alone, now and in the future?
