/data folder not present in recovery mode

[amazones]

I want to backup my system by pulling system-data and user-data folders from the /data catalog. When I boot into recovery by pressing vol+ and powering phone on, the data directory is present but it's empty. Is there something I'm doing wrong? I'm checking the directory by plugging the phone into computer and executing adb shell.
Im on an Oneplus 5T

@amazones I've never used adb shell and still have a lot to learn about Linux internals, so I'm going out on a limb here. Could be permissions? With UT Terminal I can cd to /data, but ls returns "permission denied". But I see everything when I sudo ls.

@amazones you can run mount -a in adb shell to populate /data

@amazones On my Volla Phone X (and in my Nexus 5 when it was working) I plug the USB cable from the phone into the PC, log on to the phone from it's screen. The phone then appears in the file system on the PC (well it does on Ubuntu). From the terminal on the PC I can then run sudo adb pull 'insert path and file name here'. Works for me.
