Nope, not a space issue since I assigned it to a folder in Windows and there is 1.5TB of free space left on the SSD that is mounted as /media/sf_FWUL_Backup. Basically, it's not finishing backing up the /system since basically I can tell the system.bin file is either 400MB in size or 1.7GB in size after 15 minutes of so into the backing up of /system when the green progress is at a small percentage and when it is full but just never completes and moves to the next thing while it backed up everything before that. I have tried switching physically to a USB 3.0 port, only used USB 2.0 ports because USB 3.0 is never good for phones from my own experience and others and always 2.0 is more reliable. I have already tried changing the RAM to 3GB from 2GB and the processors to 2 as I have 32GB on a Intel Core i7 2.2Ghz on a notebook. And this is with the latest SALT 3.9-0.STABLE, I have already rebooted the host machine as well.

So is there anyway to figure out what is causing the hang so it actually backs up everything since system is actually the last thing I would be concerned about as I already have the rootedsystem.bin which will recreate the system partition as needed and the only thing different is really just adding /etc/resolv.conf, newer SuperSU, newer busybox, tcsh, bash and the location spoofer app. Is there a way to manually do the full backup since is there really any benefit to using SALT vs just using the lglaf as part of FWFUL as I thought lglaf can do the backups as well except I am not sure what commands to use to do a full backup even though all I really need is /sdcard as basically everything else is already on the MicroSD Card with Titanium Backup with the exception of a few apps that stores things that are not backed up in /sdcard so it seems I really just need to backup userdata and can basically just extract the .bin and manually copy the stuff back to /sdcard after flashing the phone along with restoring with Titanium Backup.

I was looking at the page here at https://xdaforums.com/android/software-hacking/tool-lg-download-mode-laf-t3285946 which does show how to backup the userdata partition which is something like:

python partitions.py --dump data.bin userdata

which will dump the entire /data partition to data.bin in the local directory but how do I get it so the the data.bin to be written to the FWUL mounted /media/sf_FWUL_Backup directory as the destination as that's the part that is confusing which is something you probably know a great deal more about as SALT can write to /media/sf_FWUL_Backup without issues doing the backups so at this time, I am looking just to backup the /sdcard aka /data/media or the entire /data as that is really all I need since I already have the other data elsewhere. Seems like there should be one more option for the SALT backup and that's allowing a custom selection of what partitions to backup instead of just basic and full.

I already tried looking at the lglaf examples but still a bit lost, how does one for example do the following inside the lglaf shell "ls -al /" and then have the output saved to /media/sf_FWUL_Backup/output.log for example?

When using the FWUL terminal, one cannot get to /root or anything under that directory as cd /root will result in a permission denied while one can get to it using the desktop folders.
