They are not. When I boot into a live session, file manager only shows the linux iso files. For instance, no /boot/efi and fstab is emtpy.
I tried mounting the sda in terminal to see the files, but was unsuccessful.
BUT I know that it restored those files as if you try to install LM from that live session, you are told: 
Since I just went back and restored the original snapshot, 21.2 is correct to what it would have restored.

              This computer and its specs are NOT the one we are restoring a deleted partition to. That is another computer.
Do you play computer games? They take a LOT of space. Crossover emulates windows to play windows games on Linux. Plus I have Heroic which has all my GOG, Epic and other installed games.
It eats space.

What do you mean by Linux iso files? 
When you go to / and do ls, what do you see 
and try 
cat etc/os-release
             
            
               
               
               
            
            
           
          
            
            
              
So again I will have to create a mount point for sda1 (boot/efi) as well as sda2 (since that is where the files are)
Then cd into it and list files?  Okay. (Pardon my many typos in terminal) 
Now that confirms the restore took place to sda2, probably nothing to efi as it confirms right before starting restore that it is restoring to only sda2.
So how to we manage to get fstab from here? locate the file and sudo nano?

cat /etc/os-release
 
 
Sitting at the /mnt/Linux prompt in terminal (where I had mounted the ext4 partition) this gets me the live session version 21.3. Yet I restored 21.2.
What does that tell us?

Exactly. 
cd etc 
nano fstab
You just make the fstab file with an editor.
That picture shows the linux filesystem is all there… you just need to fix fstab, and hide grub.cfg, and put grub on the disk, and it will boot.
             
            
               
               
               
            
            
           
          
            
            
              And the fact that cat command says ver 21.3 even though I restored v 21.2 doesn’t give us cause for concern?
             
            
               
               
               
            
            
           
          
            
            
              So sitting at /mnt/Linux$ 
sudo nano fstab gives me a blank fstab file.
Do I need to be more specific? Like cd into /etc?

Did you do 
cat /etc/os-release 
or 
cd to the mount of / 
cat etc/os-release
You might have catted the live system… it is easy to make that mistake with mounts.     Always do pwd to make sure you are where you think you are.
I made the same mistake this week,  and edited fstab in the wrong linux.
Same mistake as above 
Not cd /etc 
cd etc 
then do 
pwd to check where you are 
should get /mnt/Linux/etc 
then what is in fstab?
             
            
               
               
               
            
            
           
          
            
            
              
I did it from /mnt/Linux$ where I mounted the ext 4 partition

Are you sure 
go ito etc and do pwd to be sure 
shoukd get /mnt/Linux/etc 
then do cat os-release. 
It is very confusing
             
            
               
               
               
            
            
           
          
            
            
              
 Neville Jackson:
 
then what is in fstab?
 
 
You were right, of course.  I was at /etc and edited the wrong fstab. Now I have opened the one from /mnt/Linux/etc and it had only the ext4 (root) UUID and the swapfile notation. 
Sorry, attached wrong pic the first time 
             
            
               
               
               
            
            
           
          
            
            
              So now I just had to add the /efi UUID. 
Now can I grub-install /dev/sda from /mnt/Linux/etc$

It looks OK.  That should be right for a boot. 
but 
check that the UUID is correct 
compare with blkid
