How To Backup Your Own Linux System Image


Many a times it happens that while Tweaking your setting in ubuntu, it get hammered and crashes frequently. Many a times, your Ubuntu may not even Boot properly, even if safe mode setting are triggered. Things can be somehow recovered by use of some Backup measures which has proved to be helpful, who have been in developing field. Then Follows some basic Tweaks in ubuntu.

In this Tutorial, backup methods discussed are:
  • Creating a Restore Point (local Storage)
  • Creating a System Image(Portable)

Method 1:Creating Restore Point

The Simplest option right now is creating a restore point which can be customised according to need.
For example, A restore may target particular setting only and rest can be discarded. My choice is using an open source software "Timeshift".


Installation

Assuming you are using Ubuntu System, 
sudo apt-add-repository -y ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install timeshift
Installers for other Linux distributions are available at following links:

Usage 

Select Create system Backup. If you want to maintan some setting or some folder go for custom backup. This can be found on settings menu. At the time of creation of this article, timeshift version 17.1 was used.

Answering:Why Timeshift...

Because Timeshift comes with some simple and handy Command line interface which can be triggered from terminal. This can help if System's Unity setting are disturbed and all you can see is black terminal screen.
  • sudo timeshift --version
  • sudo timeshift --list
  • sudo timeshift --restore #interactive 
  • sudo timeshift --restore --snapshot "2015-01-21_19-28-43" --backup-device /dev/sda2 --target-device /dev/sda1 --skip-grub 
  • sudo timeshift --delete #interactive timeshift --delete --snapshot "2015-01-21_19-28-43" 
  • timeshift --delete-all #completely remove all snapshots



Method 2: Creating an ISO image of Your Sytem

This method is no different from previous but helps to create a portable image of your Operating System with all your settings and all your preferences. My choice for this is a simpler soft called "RESPIN"

Installation

Adding Repositories:
 sudo add-apt-repository ppa:sergiomejia666/respin
 sudo add-apt-repository ppa:sergiomejia666/xresprobe 
Updating the configs:
 sudo apt update
Installation:
 sudo apt-get install xresprobe respin isolinux
To create a restore Point here we just simply run:
sudo respin backup ubuntu_custom.iso  #your choice of name in place of ubuntu_custom
This ISO can be ported(Take care of machine architecture as not all settings are portable) to another system and will retain all the installations you did. Also if you are developing memory modules in Ubuntu its better to keep an ISO version of your settings because Ubuntu gets Highly garbled in these developments

With these settings now we can go for tweaking various parts of Linux.

In this tutorial, we'll learn about the Kube-proxy in iptables mode. Basically, we'll see how Kube-proxy create iptables that help in load balancing and service discovery. If you are not familiar with Linux IPTables I would recommend to check out my tutorial on IPTables here  first and then come back to read this tutorial. Kube-proxy Kube-proxy when running in iptables mode basically watch kube-apiserver for new endpoints and create corresponding iptables rules and iptables are fully responsible for service discover and proper routing of traffic to corresponding pods. Kube-proxy needs to run on all k8s worker nodes. Below is a small video describing the working of kube-proxy in iptables mode.  src:  https://www.slideshare.net/CJCullen/kubernetes-networking-55835829 Now that we know what Kube-proxy is and how it Kube-proxy works, let deep dive into the types of iptables Kube-proxy adds to the firewall. Kube-proxy added IPTables To learn this let's consider an example. Cons...

  In this tutorial, we'll learn about the system design for PasteBin. If you don't know what Pastebin is here goes its definition. Pastebin is a type of online content hosting service where users can store texts to share with others over the internet.  Pastebin system design requirements  Functional Basic - User should be able to paste the text, generate the link and share the link with other users. There should be the max size of the text that our system will support (say 10Mb) Users should be able to provide the custom URL path for the link created. Like if a user wants to create the links  www.pb.com/letlearn, he can give this URL and pastebin should create a link using this URL to share with others. The link or paste expiry feature should be there for each stored text. There can be default expiry time say 1 year but this should be configurable. Personalization means the user should be able to login to track all the pastes created by him and manage them. Non-Funct...

Lets learn "What is CDN?"

  In this tutorial, we'll learn about What is CDN ( Content delivery network ) and how it works. Introduction Whenever you access any website on your mobile phone or laptop or any other device using the internet connection, you must have seen for some of the websites the pages load quickly, and for others, it takes considerably more time. Why is that?  Basically loading any website requires the data needs to be downloaded from the server where that particular website is hosted. For e.g, if you are accessing a website in Canada which is hosted on a server in India, it will take some time due to the latency but if that website is hosted on servers in Canada itself it will take less time to load due to low latency. So internet experience can be bad for some of the websites when clients and servers are separated by a long distance. One could argue that why not host the website on servers in all regions but that would increase the cost a lot. The better solution is to use CDN. Let'...
