I am running SyncThing on a Synology NAS, to which 5 devices are syncing, each to their separate folders. Everything works just fine, and I am quite satisfied. But as the external devices are running (very) remotely, I would be very sad, if for some reason I would have to get a hold of them to get data out. The made-up scenario is this: The NAS crashes, burns, gets stolen or something. Then what? I am aware that it is of course possible to back up the already synced data regularly, so this is not lost, but what if the crashed/lost NAS is replaced with an identical NAS, perhaps even with the config file from the old NAS?
- Will the remote units be able to sync to the new NAS with the restored config file?
- What happens to the (old and perhaps new, as in generated since the crash) data on the remote devices? Do they see the server as now having been emptied, and delete their local files (=new data is lost)?
I read this post: https://forum.syncthing.net/t/epic-mixup-of-files-after-disk-restoration/13492 and found it to be almost the same issue, although not as such resolved and not concerning the exact same matter.
