How to get all (not excluding any times) data in home (or maybe /) directory of 16.04 Ubuntu Touch tablet?

I have some programming data on like my Ubuntu Touch Nexus 7 Flo 16GB running Ubuntu Touch 16.04. I have already tarred home directory on it and tried all types of computers I can to get off data with all timestamps. Created at and other than last modified do not stay, even with tarring I am unsure. I ran this on home directory to make a tar of home directory.

tar -p -czvf archive.tar.gz .

That seems to have worked but like my computers do not recognize those timestamps so I can't be sure. That end dot was in command. I am trying to get all home directory files to a computer from that Ubuntu Touch tablet and maybe have a full backup of it that if I had another Nexus 7 Flo or something I could restore all data. I tried to tar root directory too, failure even with sudo. I would prefer a full backup like system image or something but do not know how to be sure. Attaching like my research. How can I be sure this worked is like my main question. I would rather not try anything dangerous with like my only copy of those timestamps. I know I have a full backup of home directory otherwise.

I have an Ubuntu current LTS with Ubuntu Pro I would prefer to use for this if I can. I also have 2 Windows 10 computers, one of which has ADB and android stuff and which I used to make it Ubuntu Touch tablet. Also, it is 16GB, not loaded, but I would prefer a straight to off tablet backup if I could. I do not really need more than home directory but more would be good. I understand I already found some things to try but I may prefer not to bloat like my tablet trying. I am trying for local, not cloud, backup.

If it helps, rsync, cp, and straight copy and paste on like my Ubuntu computer leave a current time created at. I understand I could write this stuff out but I prefer automation. I am also trying for an any machine readable format one once so just raw system image may not work for all like my purposes. That would be 2 backups, a system image (which I know how and can do) and an any machine readable thing with all timestamps (which is what I may ask help with). X E.

You know what the dot does, right?
 
Partly, according to what I know that is where relative to terminal and . makes it current directory. Should I have used ./ or ~/ or /home/phablet? I am sorry, I am new to this. In that archive all were in a ./ directory. I got a whole ~/ backup not including created at. Also, I think I know that recovery has a backup option. Thanks Antero360. X E.

If it helps, data on that tar file said it totalled 1MB and it seems to have included all home directory files without created at or accessed at. I do not need accessed at but created at would be good. X E.
 
So what to do after I set that up? I know how to. Will a system image store all that data? I found how to make a system image by installing phablet-tools. All I care about is that home data and timestamps. I do not need anything else. Still good to have a full backup though. I tried backup/restore in recovery, just loops back to main menu. X E.

I found that I could maybe just make a disk image of this device but a question is, how to test it to be holding all data I like want. How to test any method is nearly like my main question. X E.

I mean, if you're not doing a complete system backup, and just backing up certain things, then I would just go with a tarball of what you want. Granted, you may need to either get everything you really want to backup into a specific directory and just create the tarball of that directory, or create the tarball in a specific directory and just add to that tarball
 
So what command should I use to tar home directory? I already tried and failed. I am storing tarballs at Music because it was empty. I am okay making a system image, I just want one that is like files any computer could understand even if I need an install for it. That tar command made a tarball with only last modified timestamps that I tried. It is ./ or ~/ isn't it? X E.
 
I think I may try a Windows computer with it again, that has worked before but there have been updates since then and last time I tried it gave a not matching anything time set. I think I need to keep screen on that tablet on entire time I copy. X E.

Again, coming back to my earlier statement... are you going to back up EVERYTHING under home directory, or cherry pick what you want to backup?

All of home directory. I also may try a system image. Maybe exclude like my previous tar attempt in tar. X E.

Since you want a backup of home, I suggest you add the backup file to a directory that is not a subdirectory of home.. so place the tar file on the directory that home lives in..so something like

tar ~/../bakup.tar ~

I think I will just use an exclude option because I do not have access to other than home directory on that tablet currently and store attempts in Music so I can exclude all attempts. Also, according to that thing you sent I should have used other than just . like I was using. I already knew what those letter parts meant. I think I will still use -p though. That is not explained there but it preserves all timestamps. Who knows, maybe I will find on another computer that it worked. X E.
 
From what I know this is what command I should use and I should do it in Home directory.

tar -czpvf Music/name.tar.gz --exclude="Music/*.tar.gz" ~/

Is this correct seeming? X E.
 
I just realized I was only using -av options on rsync and rsync has -h option to list all options and tar has --help option to list all options. I now realize I can use rsync but tar will not do any more than just modified at times. Like my new rsync command to try:

rsync -vrlptDAXUNtg --open-noatime (from) (to)

With that it should preserve everything. Thanks @Antero360 and these built in help things are like better. zzzcode.ai was wrong on this one. If this does not work I am screwed. I realize v is an added and not a needed but I would prefer to know like everything. If there is anything wrong with this feel free to inform me and I think I know all I should now. X E.
 
I discovered that rsync on like my computer does not support "-N" so I am almost screwed but I made a ruby program to record file properties to a file. This should work seemingly. It does make it in current directory. I would have to copy it to that tablet. Anyway, everything does not work with this so far, but I may have a solution. X E.
 
I made a copy of times using like my program modified on like my computer writing to like my computer with no transfer to that tablet. It worked. I now have a computer and other device ruby program that records file and directory properties. X E.
