Backup of many APKs time out and make backup fail

[azarok]

I spoke with Nick from Clyxos, and he told me to provide you the log. There are some personal details in the log. How might I attach the file such that no one a part of you could view it? Thank you

@chirayudesai didn't we have an email address for these cases?

[chirayudesai]

We have one for calyx, [email protected]

IIRC GitHub doesn't allow others to open private / confidential issues, otherwise that'd have been another way.

[azarok]

Thank you both, I have just emailed you with the log.

The backup proceeds successfully for a while but eventually encounters a particular package, stalls, and times out. (I removed anything even close to being identifiable from this snippet.)

Good find @t-m-w! I think this is the same issue we found when porting to Android 14: https://github.com/seedvault-app/seedvault/issues/564#issuecomment-1758222387

There's so many APKs to backup for this user and the connection is probably too slow to finish all of them within the transport timeout.

CalyxOS 5 bumped these timeouts, but they might still not be sufficient. @azarok for now you could disable APK backup settings, this should work around the issue. During restore, if Aurora/F-Droid are installed, you should be able to manually install these apps. Not great, but better than nothing.

Some extra bit from the log:

I BackupNotificationManager: 22/263 - 8% - Opt-out APK for [redacted package]

I think it was trying to back up the app's data with key/value, but maybe I am reading it wrong?

In this case, though, I received word (and permission to share) that excluding Santander (uk.co.santander.santanderUK) allowed the backup to proceed.

[azarok]

As soon as I excluded the santander app, the backup worked flawlessly. Everything else operated without a hitch.
