(TIP!) Backup Ubuntu to bootable USB

Post by **Merdeka** » Fri Sep 25, 2009 2:57 pm

I think we al know this problem. We have a nice setup running Linux and we decide to upgrade something or install something new.

And we screw up our complete install. Happens to me all the time when I test stuff..

What I do now is just follow the steps on this site: http://www.ubuntugeek.com/creating-cust ... ersys.html

Using Remastersys I make backups to iso files. And when I break something I just burn the iso to an USB-stick using Ubuntu's USB Disk Creator and reinstall from this USB Stick.

I keep my data stored an a second harddisk so my typical ISO is around 1,5GB

Hope this helps anyone out.

Whenever i screw it up i fix it normally

i have never reinstalled a linux machine because i "screwed" it up.. i always went for the "dammit, it has to work without reinstalling approach"

Or you can just install it on vmware, and make snapshots

Or you can just install it on KVM, and make snapshots [:)]

Or use RAID0 and disconnect one drive when testing and let it rebuild afterwards if things go wong

raid 0: http://www.raid.com/04_01_00.html
Not a "True" RAID because it is NOT fault-tolerant
The failure of just one drive will result in all data in an array being lost.

raid 1: http://www.raid.com/04_01_01.html
100% redundancy of data means no rebuild is necessary in case of a disk failure, just a copy to the replacement disk

Grumble!!. Why do they make those tiny keyboards or is it just my fat fingers. :0)

Raid-1 (Two disks in mirror on the controller)

The 0 is (are on my keyboard(s) between) the 9 and 0.
The 1 is between the ` and 2.. Your's finger(s) must be really fat

You could check the num-pad. (Yes, you can hardly believe that but modern keyboards have that standard)
The 1 is above the big, double-sized key with 0 on it.

Yeah, But trying out a new kernels and device support for DisplayLink screwed up my install real fast.

Putting everything back from the ISO I created before I started was a lot quicker.

And my girlfriend isn't always to happy when things break. We use our system to watch TV to, so it's not always convenient to work on it. Now I can just boot from my live ISO and she can watch here soaps again.

Or I just boot the ISO in my laptop and work on things from there.
