Dear All,

My apologies for OT question.

I wonder if someone of Android smartphone owners backs up their device 
and user/application data NOT to google cloud.

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. To my storage, NOT 
TO GOOGLE CLOUD that is. adb lets me back up system and applications 
(and data on add-on flash card), but not application data stored in 
internal storage (say, off-line maps downloaded by offline map application).

I knew when buying android ("gogloid") I'm not becoming an owner of the 
device. I also know that after flashing one of "un-googled" systems 
(waiving off the warranty on that device) I will not get rid of all 
google code. There is proprietary chunk of it the android kernel... Plus 
proprietary drivers ("blobs" is the word android people use if I'm not 
mistaken). I also have seen google "appliances" on several "big" (say, 
class B) networks, not registered in DNS, carrying non-routable 
("private address space") IP addresses, which are resolved as google by 
DNS servers provided to DHCP clients inside these networks... So, no, I 
have no illusion about getting away from almighty big brother.

I just want my data backed up to my device, accessible to me and usable 
for recovery without need of network access, and existence of some third 
party servers on the network.

I know, Apple iDevices are a bit better data wise, and Apple has [quite] 
a bit better reputation, though these are still Apple devices, not yours ;-)


Any advise, anybody?

Thanks a lot in advance!
