I switched from (paid) Resilio Sync to Syncthing. Very happy so far, but I ran into one issue that I’d like your help on.
I back-up phone photos to my NAS. Have been doing it for years.
On NAS:
/mnt/data/GalaxyS8/Camera
/mnt/data/GalaxyS8/Whatsapp
On my phone I configured two send only folders: Camera and Whatsapp Images. On my NAS I pointed the folder to the existing location (a.k.a where my 8+yrs archive is).
The sync is working, but Syncthing deleted my entire archive and replaced it with the content that is on the phone right now. I meant to only add the phone content and of course preserve everything that was on the NAS. I have a backup, so I didn’t lose anything, but how do I configure this correctly?
The behaviour I’m looking for is the same as the backup functionality in Google Drive and Dropbox on a phone. The ability to sync your mobile pictures to a folder that keeps growing. If content is deleted from phone it should remain in the folder on my NAS. Is this possible? I know for sure this is a use case that works on any other sync platform (Resilio, Dropbox, Drive, OneDrive).
