App data backup by git possible?

I am using neo backup often i run into storage issues so i am wondering if there is a possibility of backing data with git, root, Termux, Tasker .

Edit: solved some issues

• storage issue was fixed by not enabling unnecessary backup options. It created massive difference for most applications, eg anki was over 1 GB, now its 9 KB.
• Some application's backups were not working( After restoring applications were crashing), for them, rather than backing up whole data, we can copy relevant data. Eg for element, we can backup by

cp /data/data/im.vector.app/shared_prefs/im.vector.app_preferences.xml %ConfigBackupLocation/element # you need root for this
