Hmm… I would say… this is not a very good error message.

Anybody want to give me advice on how to back up everything important from an Android phone? Assume I have about… eight hours and somewhere in there I have to sleep.

I guess I'm using adb, but I barely know what I'm supposed to be grabbing, also neither adb pull nor the https://github.com/jb2170/better-adb-sync tool google says to use is like… y'know… doing anything…

What I really really REALLY need is an android file extraction tool that, when it hits a permission error on trying to download a file, will skip that file and download everything else instead of hard aborting
Failing that, what I'd really really REALLY like is a way to back up my Element/Signal keys/conversations without uploading them to the Element or Signal server. And also ideally without my phone having a screen

Me: I would like to back up my files to my laptop

EVERY SINGLE PHONE, APP, OPERATING SYSTEM, APPLICATION, LITERALLY ANYTHING: Sure, just send the files to us over the Internet

Me: That is not what I said

@mcc the sane backup system is why i bought Titanium Backup app for Android. It was in early stages of android and I had a phone that i had to manually update firmware for, because it was a Windows phone. Titanium Backup was a amazing tool. It worked and only required root to do additional stuff. Just zip "everything on the phone" in this folder => just install everything that is archived in this folder.
I didn't used it for about 5 years, but maybe it will help you.
@muhanga I've looked at that one before I think but I think it requires root
@mcc yes it requires a root for most advanced stuff which is sad as most of the time it is not easy to get root.
