Backup & Restore your Whole Ubuntu Computer using Remastersys

If you want to completely backup your whole Ubuntu computer, including system files and personal data, then you probably want to first look at Remastersys.

This open-source application can create a snapshot of your computer and make an ISO image of it, then use the image to restore unto a different machine or the same system.
 
There are some limitations with respect to how much data can be created into an ISO image. Reading from the creator, it seems that there’s a 4GB size limit of what can be backed up and created into an ISO image of your computer. So, if you have a lot of media files and other data that you can safely move somewhere else before backing up, that to. Or use the exclude option with the program to exclude backing up of some unnecessary directories. For your average Ubuntu machine there’s no need to worry, you should be able to back it up easily.
