On my Samsung Galaxy Nexus, I have CyanogenMod 10.1, which is based on Android 4.2. In previous versions of Android, I would copy the ClockworkMod backups from
/data/media/clockworkmod/backup to my PC. In Android 4.2, connecting with
adb shell won’t let you look at the data directory. To fix this, you need to set root permission in Settings > Developer Options > Root access. (If you don’t see Developer Options, it’s because it’s hidden by default in 4.2 and up. Go to Settings > About phone and tap Build number seven times to enable it.)

adb root before

adb pull /data/media/clockworkmod/backup.
