You might want to transfer your internal storage such as /sdcard to your computer directly and compressed as fast as possible.
So here is how you do it (on linux using bash):
Reboot your phone into TWRP, connect your device to your computer, and run the following command:
In this example your data (in this case /data/media/0) will be backed up to your computer into the file sdcard.tar.
Compression is done automatically and you will get a nice output on your terminal on which file is being backed up currently.
When everything is finished you should get a message similar to this on your terminal:
(On the result of this you can see that the speed is around 12 MB/s, means that 1 GB backups in less than 1 minute)
When you get that, it means that your backup has finished and you can safely remove the usb cable.
Note that you can do this with any directory on your device, so if you desire to back up /data, just write data instead of data/media/0.
Example of the resulting sdcard.tar file (opened on my computer):
Decompressing your data directly to your device might get a little trickier:
If that does not work, you can just extract the content of the tar file normally onto your computer and then copy the files over using adb push or copy the tar file to your phone and extract it using the following command:
And that should do the job as well.

Whatever you do, it's your decision and you do it on your own risk!
I am not responsible for bricks, any kind of damages, data loss or any other unwanted result!
Everything you do is done on YOUR OWN RESPONSIBILITY!

Decompressing your data directly to your device might get a little trickier:
Code:
adb shell mkfifo /rst.pipe && adb push sdcard.tar /rst.pipe & adb shell 'cd /; cat /rst.pipe | tar -xv'
If that does not work, you can just extract the content of the tar file normally onto your computer and then copy the files over using adb push or copy the tar file to your phone and extract it using the following command:
Code:
adb push sdcard.tar /sdcard/sdcard.tar
adb shell 'cd /; tar -xvf /sdcard/sdcard.tar'
And that should do the job as well.
