I am looking at a way to use syncthing as a way to archive data from a laptop with limited diskspace to a desktop with lots of space.
So on laptop if I have a folder ‘Archive’. I move files/folders there, wait for them to be synced. Then delete them on the laptop to free up space, knowing they are saved on the desktop.
I’m not sure if “Send & Receive Folder” are for this use-case.
You need to have some kind of a backup solution on the desktop that would properly move/archive the files. Otherwise, they will be gone as soon as you delete them on the laptop. As said above, you can use Versioning in Syncthing to keep the deleted files around temporarily, but you will still likely need to move them somewhere else later.
If you want to do everything though Syncthing, you can also set the Versioning to use a custom folder to keep the deleted files in, or alternatively you can use the External Versioning to move the files to a completely different location.
@JungleSync why don’t you turn your idea around?
Create folder “MoveToArchive” (send/receive) and sync it with Syncthing to desktop.
On desktop create script that moves all files to real archive outside of syncthing folder.
Now whenever you need space all you have to do is move files to this folder on laptop.
