Feature request: split a full backup so per-app backups for easier restoration

[oernii]

Full backup often only work on the phone which made the backup, many vendor apps cause crashes if restored on another device/emulator.

Would it be possible to add an 'split' option, which would take an full AB file and create for each app a smaller AB just for the apps themselves?

[nelenkov]

You can backup a single application by specifying the package name.

If the app depends on any device-specific data (IDs, keys) it is likely to crash when restored with data from another device. Simply clear data for the troublesome from system Settings.

Well, when you have an encrypted device, it will ask for a password for EVERY app. Just done that.

@oernii check this links should work https://sourceforge.net/projects/tar-binary-splitter/ https://sourceforge.net/projects/adbextractor/

[superbonaci]

There are more utilities check for you https://sourceforge.net/projects/adb-split/

[nelenkov]

You can set the password in the ABE_PASSWORD environment variable if you don't want to type it each time.

[nelenkov]

Sorry, it's ABE_PASSWD

@oernii I've made an alternative for android-backup-extractor written in Python that can also split and merge .ab files (among other things), see https://github.com/Own-Data-Privateer/abarms
