restore just one app's data manually - ie: via ADB restore

[JohnTheLearner]

Manually backup data for only a single app from a seedvault backup...maybe using ADB restore? I don't want to restore the whole SV backup or any of the system parameters...just data for a single app.

I've tried restoring using ADB using just one app's directory of data taken from a SV backup and re-packed into an adb backup file as shown in https://stackpointer.io/mobile/android-adb-backup-extract-restore-repack/372/. The OS prompts, runs the restore, but seems to not take effect in the app...even after a restart. TIA.

So to clarify, is there a way to manipulate the backup found in ./SeedVaultAndroidBackup to remove system artifacts and other apps not desired to restore, then re-crypt the backup such that one could restore that on new hardware? I understand this isn't a typical use case and would be more of a manual process. I See the new, v1, extractor, but extracts-only and I don't see an encrypt option to re-form a backup once the above modifications are complete. TIA and feel free to PM if preferred.

The manual process here would involve having a tool which is able to re-crypt the backup. we do have the seed (which can be used to generate the key), but such a tool isn't available right now.

Another way would be to put the backup into the typical adb backup/restore format, not sure if that'll still work on latest Android though.

In the future, SeedVault itself will allow you to selectively restore.
