OVERVIEW
If you want the backup at the local machine using SFTP, follow the below steps:
STEPS -
1 - Make the compressed file
Go to the document root.
Ex: If it's using an Apache application layer, then it should be /var/www/webroot/ROOT.
Make the .tar, .zip, etc. file of ROOT folder.
Then give full permission to a compressed file:
chmod 777 root.tar.gz
2 - Download the file
Connect to your node using SFTP
You can also take the backup using ssh.
wget http://name-of-environment.cloudjiffy.net/path of file.
Ex : wget http:///root.tar.gz
