I have an Acer Aspire One running Lubuntu 10.04. I have configured it quite much and would like to backup the whole file system (excluding my SD card where I keep my data) to be able to get it up and running quickly in case of disaster.
I know there are many discussions on good backup solutions, but I would like help to find a specific solution that is very simple to use. And with that I mean a command line solution, preferably in just one line, that makes a (compressed) copy of the file system to a mounted USB stick.
One of the most important aspects of the solution should of course be that it is very easy to restore the system, even if I forget the details on how I made the backup. So, maybe the USB stick should be bootable and when booted from, it should restore the computer. Or anything else that is about that simple.
Does anyone already do something like this, or is there a backup implementation aimed towards this use case out of the box?
To clarify a bit: if I could get a tangible proposal I would be very happy. Like for example a specific command line:
<command> --from /dev/sda --to /media/usbmemory/backup.bkp
Or whatever would work! :)
