Does there exist an Android app that will backup SMS messages to a private Nextcloud 21 instance?
I tried “Nextcloud SMS”, but it doesn’t seemingly work with NC21, and appears stale – last release was 2018, as far as I can tell. Last bug report was 1 year ago. This app appears to connect successfully, but doesn’t transfer any data, nor generate any errors or other messages.
I searched this forum for “SMS”, but struck out. Surely this seemingly-common use case has an existing solution?
Replying to myself with an update. I found and installed “Phone Sync”. Early returns are not good – it throws a server error when I try to access it through the Nextcloud web, which was literally the first step I tried. I have not yet checked the log file for details, but if it fails on step 1, I doubt I can rely on it.
