Yes, I do run ownloud server (for the department), which I can trust as myself (or rather I trust myself ;-). Owncloud client can back up regular stuff that file manager on android has access to (that is photos, documents). However, owncloud client is just a regular application on android, and it has no access to /data/data - this is the place which android applications use by default for their, and some of them are not configurable to use different place to store their data. Example: offline maps (e.g. maps.me). What I discovered on the version of android my new cell phone runs is: every application runs under its own username (Hooray from security point of view!), and stores data into its own directory under /data/data accessible to that (only) username application runs under. Apart from that, unlocking bootloader, but not rooting the device allows me to back up everything (except for /data/data where application data are stored). > radicale - open source CALDAV/CARDDAV service - I keep my contacts on this > using davx5 on the Android side. > > There are also Android implementations of rsync - I use one > (arcosync) that is no longer in the play store That is my impression, several things that give you more freedom (== more owneship of "your" device) were eradicated from "play store". > to backup photos and a > selection of application files. > >> I just had to get new smartphone, and discovered that short of rooting >> device or unlocking bootloader and flashing one of "un-googled" android >> builds I can not find the way to back up everything.

Hm. Just went whole way: wiped it and flashed LineageOS. Though google code is still there in binary only "blob" of kernel, and likely in proprietary binary drivers and components firmware, it feels good for the moment. Thanks, everybody, for all your advises!!
