I want to make sure that using adb backup -apk -shared -all -f ~/backup.ab will also save /data/misc/vold?

I am trying to backup before rooting, in order to be able to gain access to the encryption key in /data/misc/vold (got corrupted SD card adopted as internal). So I want to make sure ih something bad happens during the rooting, I could still access the backup version of /data/misc/vold?

Thanks!

  • It doesn't get backed up. For verification you can backup with that command, unpack the backup file and see the contents yourself. – Firelord Sep 29 at 23:41
  • Mmh, does not seem trivial to verify that by unpacking. Would that work anyway if I encrypted the system? More importantly, is there then a way to back up also /data/misc/vold ? Thanks!! – Matifou Sep 30 at 1:46
  • Try this to unpack the backup file. As for vold, it can only be backed up using root access. – Firelord Sep 30 at 2:23
  • thanks! So you are saying that it is not possible to backup vold without being root? This is a conundrum, as I am precisely trying to root to access vold, and the process of rooting is likely to erase that file – Matifou Oct 3 at 16:48
  • Unfortunately, this is just not possible without root. :( – Firelord Oct 3 at 18:41
