Create a tar.gz file and transfer it to network server

I have a Raspberry pi running on my home network along with a Macintosh that acts as a backup server. I am attempting to craft a Python3 script that will run on the Pi to create a tar.gz backup of the Pi's home folder (along with all of the contents) and transfer it to the Macintosh using SSH. I have the SSH connection (using keys) running but am stumped when I try to create the backup file and transfer it.
My code so far:
#!/usr/bin/python3
import paramiko
import tarfile
import os
ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connnect(hostname = '192.168.1.151', username = 'usernamehere')
print("I'm connected!")
#The following statement is the problem as I see it
tar czvf - ./home/PiOne/ | ssh_client -w:gz "cat > ./Volumes/PiBackups/PiOne/PiOneClone.tar.gz"
print("File transferred!")
ssh_client.close
I would appreciate any help in creating the script!

I think there is something easier to transfer a file from your VM to your local machine. Also that you are using SSH
scp -i /path/your/targz/file user#ip:/path/to/local/machine
Check permission while doing that using
ls -lh

Paramiko ssh connection to windows host. Empty stdout of "VBoxManage.exe guestcontrol run" command

I'm writing python script executing bash script inside virtualbox VM using paramiko python library. The code snippet below:
stdin, stdout, stderr = i[2].exec_command("\"\Program Files\Oracle\VirtualBox\VBoxManage.exe\" guestcontrol \"virtnet_proxy\" run --exe \"/home/username/show_ip.sh\" --username username --password password" )
exit_status = stdout.channel.recv_exit_status()
if exit_status == 0:
proxy_ip=stdout.readlines()
print ("got proxy ip from host ", i[0], proxy_ip, stderr.readlines())
Connects to windows host and
should print ip address of a VM's interface. If you run this command in cmd it works fine but using paramiko ssh client, stdout is empty. If you run similar code except you connect to linux virtualbox host (and run linux command) stdout.readlines() works fine and contains output of bash script. Stderr output:
VBoxManage.exe: warning: Error getting stdout handle: VERR_NOT_IMPLEMENTED\r\n', 'VBoxManage.exe: warning: Error getting stderr handle: VERR_NOT_IMPLEMENTED\r\n
Bash script:
ips=$(hostname --all-ip-addresses)
read -ra arr <<< "$ips"
echo"${arr[0]}"
As i said stdout is empty only if you connect to windows host and run vboxmanage command on guest machine.
Thank You in advance,
Wojtek

EDIT: I've changed ssh server on windows host from OpenSSH to FreeSSHd and the code worked !

Cannot ssh to run a remote script using Python

I have the script below (test.py on 1.1.1.1) to run another remote script on another server (script.py on 2.2.2.2). I have set up the ssh keys so I don't get prompted for password.
import subprocess
USER="user"
SERVER_IP="2.2.2.2"
SCRIPT_PATH="/home/abc/script.py"
print ("ssh {0}#{1} '/usr/bin/python {2} aaa bbb'".format(USER, SERVER_IP, SCRIPT_PATH))
rc = subprocess.check_output("ssh {0}#{1} '/usr/bin/python {2} aaa bbb'".format(USER, SERVER_IP, SCRIPT_PATH))
script.py itself is on 1.2.3.4, and takes in 2 arguments.
If I copy the command that is printed out in the script, I can execute script.py successfully on 1.1.1.1. But running test.py on 1.1.1.1 gives me an error:
OSError: [Errno 2] No such file or directory
I don't understand why the script didn't work but the exact same command works on its own.

Use the additional argument:
shell=True
Your command will be:
rc = subprocess.check_output("ssh {0}#{1} '/usr/bin/python {2} aaa bbb'".format(USER, SERVER_IP, SCRIPT_PATH),shell=True)
I assume you need a shell to run a python script.

If your question is to address the need of executing a remote command and not making your script working - then if I could introduce Paramiko:
import paramiko
ssh_handle = paramiko.SSHClient()
ssh_handle.load_system_host_keys()
ssh_handle.connect(
hostname=address,
port=int(port),
username=login)
stdin, stdout, stderr = ssh_handle.exec_command("whoami")
IMO it's currently the most "usable" SSH library and works just fine in my projects.

paramiko.exec_command() not executing and returns "Extra params found in CLI"

I am trying to ssh a server using Paramiko and execute a command. But the paramiko.exec_command() returns with an error.Why is this happening?
This is my Python script:
import paramiko
ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('10.126.141.132', username='usrm', password='passwd')
stdin, stdout, stderr = ssh.exec_command("show chassis")
print(stdout.readlines())
ssh.close()
When executed it returns with this message:
['Extra params found in CLI, this is not supported, exiting the CLI session:\n']
I am using Python 3.5.2 :: Anaconda 4.1.1 (64-bit) with Paramiko on Windows.
I have tried the commands manually and it is working.

Based on your latest comment:
I installed a Cygwin Terminal and SSH'd the server with the command...it came up with the Extra params error. Command I executed: ssh usrm#10.126.141.132 "show chassis", Output: No entry for terminal type "dumb"; using dumb terminal settings. Extra params found in CLI, this is not supported, exiting the CLI session:
it sounds like the usrm account's login shell on the SSH server is not allowed to run commands in the non-interactive way. To solve the problem you have to use invoke_shell() like this:
chan = ssh.invoke_shell()
chan.sendall('show chassis\r')
s = chan.recv(4096)
print s

Reading Perl script command output using paramiko from remote ssh

I can't read a perl script command out from shh. I can reading things like ifconfig, pwd but I installed an application written in perl but cant read out from its command from another server when using remote ssh. Tried a lot of steps
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname=sys_ip,
port=22,
username=sys_username,
password=sys_password)
cmd = "cd /; export TERM=${TERM:-dumb}; commandforperlscript"
I get no output and no errors.
