Sure that doesn't protect your data from any other attack vector but it allows you to travel with less risk of getting detained by law enforcement of a country you are visiting. You get asked your password, you can give it, and they see a phone that is used like a dumbphone. If you get questioned for that a simple "my phone died yesterday, a friend just gave me his old pixel". If you need more stuff/information during your travel you would basically only need to remember the passphrase to access a password manager or a remote ssh server but you can restore only the stuff you need when travelling and and wipe again at any moment.
Having said that maybe it is better to set this up some way but not have it builtin so that law enforcement doesn't expect that any grapheneos user would have his data on an sftp server somewhere by default. Otherwise we are back to point 0 where they would ask to connect to it and restore to a phone they own. Oh and have a dummy google account you only used to purchase a couple of silly stuff on amazon, aliexpress and shein and random subscription of various "non risky subjects" on youtube. The gmail address would quickly be filled with enough spam to look genuine.
I am travelling abroad in 3 weeks for a month and I am seriously considering wiping up my grapheneOS phone before flying. I am wary that I could be targeted at a border just for having a google pixel with grapheneOS. Or maybe I should just leave my main phone at home and only travel with a new empty 150€ phone with only my main family emergency contacts. I don't remember ever being asked to show my smartphone at a border but you never know when it will happen. Thanksfully until you reboot it there is nothing that shows from the lockscreen that it is not running the regular google pixel android.

So basically one needs a webdav server somewhere or an usb flash drive.
> Seedvault which was originally written for use in GrapheneOS by a GrapheneOS user is a consequence of the 2018 takeover attempt on the project, which the people currently in defacto control of Seedvault were heavily involved in.
Seedvault is currently maintained by the CalyxOS team but I've never heard about this stuff. Does anybody know what happened?
If the regime is going to just start taking people then nothing will stop that, but the goal is to stop the usefulness of this sort of thing as an intimidation measure - or at least drag it to the forefront and overthrow the regime.
You don't avoid scrutiny by being wierd and hiding things, but by hiding in plain sight by being ultra boring.
On a related note, a recent article [2] also describes how GrapheneOS helped a journalist protect his work and his confidential sources citing the 18-hour auto-reboot feature that returns the device to Before First Unlock (BFU) mode, where keys cannot be extracted.

Also worth mentioning that you can set auto-reboot to a shorter period (down to 10 minutes). So if you anticipate situations where your phone can be seized (border crossings, demonstrations), it's worth temporarily setting this to a short time period (or rebooting your phone yourself to get to BFU).
Secondly, it is important to get as many people to use GrapheneOS as possible, including non-tech people. The more widespread it becomes, the harder it will become to paint this picture.
The point is to at least make them resort to hitting you with the $5 wrench, at which point they're probably committing a more serious offence than what you're up for (dependent on country).
The offenses of a regime at its apex would've led to it being stopped had they started out that way, but they didn't.
What you've hit on is the basic problem of treating privacy as a means to an end though: no level of it protects you from fascism, but it is a means by which fascism can be opposed - in many cases at personal cost to yourself.
In theory I have no secrets, and the contents of my phone or life if public would be of no consequence to me. In practice, when the regime starts flustering itself that I have no secrets for them to reveal the hopefully people will oppose it - or I get a decent warning that it's time to bail.
I carry a burner phone when travelling most of the time anyway. It has access to email only, 99% of which is in offline folders anyway.
The duress password does not wipe the phone. It wipes the encryption keys from the secure element. The phone's storage is the backup, but it is worthless, unless law enforcement has an attack against AES that does not require a brute force attack (unlikely).
And the primary copy is not a backup.
