Backup Your Entire Linux System Using Rsync

First, insert your backup medium (USB thumb drive or External hard disk). Then find the drive letter using ‘fdisk -l’ command. In my case, my Pen drive id is /dev/sdb1. Mount your drive to any location of your choice. I am going to mount it under /mnt.
$ sudo mount /dev/sdb1 /mnt
To backup the entire system, all you have to do is open your Terminal and run the following command as root user:
$ sudo rsync -aAXv / --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /mnt
This command will backup the entire root ( / ) directory, excluding /dev, /proc, /sys, /tmp, /run, /mnt, /media, /lost+found directories, and save the data in /mnt folder.
Let us break down the above command and see what each argument does.
  • rsync – A fast, versatile, local and remote file-copying utility
  • -aAXv – The files are transferred in “archive” mode, which ensures that symbolic links, devices, permissions, ownerships, modification times, ACLs, and extended attributes are preserved.
  • / – Source directory
  • –exclude – Excludes the given directories from backup.
  • /mnt – It is the backup destination folder.
Please be mindful that you must exclude the destination directory, if it exists in the local system. It will avoid the an infinite loop.

To restore the backup, just reverse the source and destination paths in the above command.

Branches, Part II

Now that we’ve covered the mechanics behind Git branches, we can discuss the practical impact that they have on the software development process. Instead of introducing new commands, this module covers how the typical Git user applies this workflow to real projects, as well as some of the problems that arise in a branched environment. To Git, a branch is a branch, but it’s often useful to assign special meaning to different branches. For example, we’ve been using master as the stable branch for our example project, and we’ve also used a temporary branch to add some CSS formatting. Temporary branches like the latter are called topic branches because they exist to develop a certain topic, then they are deleted. We’ll work with two types of topic branches later in this module. Amid our exploration of Git branches, we’ll also discover that some merges cannot be “fast-forwarded.” When the history of two branches diverges, a dedicated commit is required to combine the branches. This ...

Policy Based Routing on a Cisco ASA

Cisco ASA 9.4 (and later) is now supporting Policy Based Routing. Yeah. Great news, since many customers are requesting something like “HTTP traffic to the left – VoIP traffic to the right”. Coming with a new Cisco ASA 5506-X I was happy to try the policy based routing feature. The configuration steps through the ASDM GUI are not easy and full of errors so I am trying to give some hints within this blog post. The main document from Cisco for policy based routing on a ASA is here . It describes the use-cases for PBR and gives examples. Configuration I am doing all of my configurations through the GUI ASDM. (I know, some people really love the CLI even for configurations, but I don’t. I am using it only for troubleshooting issues.) For this lab I am using a Cisco ASA 5506-X with ASA version 9.5(1), while ASDM is version 7.5(1) . In my lab, I have a default route to ISP 1 (gi1/1) and a different connection to ISP 2 (gi1/2). There is no route to ISP 2 in the ro...
