Howto: Backup and restore your system!

source: http://ubuntuforums.org/showthread.php?t=35087

Hi, and welcome to the Heliode guide to successful backing-up and restoring of a Linux system!

Most of you have probably used Windows before you started using Ubuntu. During that time you might have needed to backup and restore your system. For Windows you would need proprietary software for which you would have to reboot your machine and boot into a special environment in which you could perform the backing-up/restoring (programs like Norton Ghost).
During that time you might have wondered why it wasn’t possible to just add the whole c:\ to a big zip-file. This is impossible because in Windows, there are lots of files you can’t copy or overwrite while they are being used, and therefore you needed specialized software to handle this.

Cracking Windows Vista/XP/2000/NT Passwords via SAM and SYSKEY with Cain, Ophcrack, Saminside, BKhive, Samdump2 etc

I get questions about SAM/SYSKEY cracking so often, and since I’m tired of pointing people to my other tutorials on the same subject, I’m creating this one-stop-shop for info on the topic. I’m putting up this one page with links to all of my videos and articles on how Windows passwords work and how they can be audited/cracked. If one tutorial does not work for you, try another. If none work for you, ask on http://binrev.com , but only if you are interested in learning how things work and not just getting into a box. The “Local Password Cracking Presentation” one covers the most from a technically standpoint, but the other ones may be more helpful for your specific conditions.
