Backup stuck at 50% without error message

[besendorf]

Today I tried to make a backup using D2D mode of all my Apps to a flash drive.
The progress stopped at 50% and stayed there for a few hours. When my battery was almost empty (I don't have a usb adapter that allows for simultaneous charging) I unplugged the flash drive. After that the notification still showed 50%.
Heres the log:

Unfortunately I don't see anything related to the backup in this log at all. :( What OS is this?

GrapheneOS build number: 2024101200

I see. I am not sure if there is a way to increase the log buffer sizes for GrapheneOS or not. In AOSP, Developer Options has a preference for Logger buffer sizes, but it is functionally deactivated (allows you to change it, but it does nothing at all, which is extremely misleading). Some OSes have undone this deactivation, and/or have set a higher default log buffer size.

Your best bet, then, would be to capture logs / bug report immediately after the issue occurs, so that hopefully all the useful information would still be present.

For now I think this is still a useful issue in the sense that the user-facing error handling could benefit from improvements.
