Why would you want this? What's the point of the server if you mirror deletes?
replyI have the opposite problem, well, my partner does. Her phone regularly fills up completely with pictures so I want to copy them to a server and then delete them from the phone, but for some reason this doesn't seem to be supported. My theory is Apple wants you to keep buying newer phones with exorbitantly priced storage upgrades.
Immich has an app that just needs to connect to an Immich server, which this would effectively be. It does the background sync, though I don't think it does the delete part.
replyThe one caveat here is that, because Apple only really allows certain apps the privilege of running in the background without being interrupted or killed, I could never get the iOS version of Immich to reliably sync photos without having to manually open it and leave the app open until sync finished.
replyThis was a few years ago, and was one of several "iOS breaks our crucial workflows" problems that motivated switching our last device over to Android, so the situation might be better now...but I've never had that problem with the Android client, so I know it's not an Immich problem.
