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

SIGNAL/ELEMENT/PROBABLY BITCOIN, I WOULDN'T KNOW: You cannot trust cloud providers and remote "apps" with your data. The appropriate thing is to store your private keys on your phone, since that is a secure, personal device you carry with you at all times

A LITERAL ROCK: Hey check out this cool trick

@mcc it's ludicrous to me that supposedly "secure" services have no answer for what to do if you drop your phone in some water and it dies instantly. and they treat you like some sort of cop for wanting to have a local backup on a general purpose computer (alternately, the super infantilizing "but that wouldn't be secure, so we'll make it completely impossible but never explain this so tons of people will have this need and then independently arrive at the conclusion that it's unsupported.)

@jplebreton @mcc sorry if this comes off as "ackshually" but all of those have mechanisms for what you want:

- signal has chat backups, which you can opt for a shared folder/drive (cloud, syncthing, whatever)
- element lets you backup room e2e keys, and recommends putting your security key somewhere safe (not on the same device)
- most reputable crypto wallets have a seed phrase to generate/recover your assets, and also recommend keeping that in a safe separate place

@jplebreton @mcc (this was a reply only to the post immediately preceding)

@xyhhx @jplebreton yeah in context part of the problem is "can i do this without a screen?" (answer: it's ok to not have a screen because there is scrcpy)

also I am going to Yu Gi Oh Trap Card you here with the ultimate Well Akshually: The signal backup feature only works on Android

(I have an Android)

@mcc wrt the rest of the thread i'm asking some other folks who might know what to do for you

@jplebreton

@mcc for signal, you can probably use syncthing to sync the backups to your computer without putting them on some cloud
@xyhhx @jplebreton i've located the signal feature can you help me find the element feature? what is it named, is it in the settings, what
@xyhhx @jplebreton I went into the Element help channel on Element but uhh it's somehow deader than IRC in the year 2024
@mcc i'm assuming you aren't on desktop?

@mcc like you have no sessions on desktop/web that has those keys?

if on mobile are u on element x or the old element?

@xyhhx I don't understand the question. I have an Android phone, a desktop computer, a USB-C cable and I am trying to extract a backup of my Element keys (doesn't need to be / shouldn't be messages, just keys) onto the desktop computer, which I can then push back to a different phone later. Because I'm about to wipe this phone for Reasons.

I do not know what "element x" is. There is an app named "Element" on my phone.

@xyhhx It is ok if I need to use the screen. I figured out how to control the screen from my computer.

@mcc element x is the new matrix app that's supposed to replace element:
https://element.io/labs/element-x

on the usual element for android:
tap your avatar, tap the cog, go to security & privacy, then export e2e room keys

you can use syncthing or your usb to transfer to your laptop

Element X | Future of Element | Fastest Matrix client

The brand new - fastest ever - Matrix-based communication app. Element X is currently a messenger; collaboration features will be added later this year.

Export and Import E2E ... | Element Knowledge

Element Web and Desktop Export Go to Element Security & Privacy settings Click Export E2E room...

@mcc i'll be up for another 30-45 minutes but until then i'll be avail if u need more help

feel free to ping me

@xyhhx thanks, you've been a big help, i think i have what i need now
