I am new to linux, and have been installing ubuntu again and again because I mess up something while trying different set-ups. I would like to have an incremental snapshot of my system so that I can revert to what I had when I made the backup.
Can I achieve what I want using either Deja-dup or Back in Time? and if so, what directories do I need to back up?
I have seen posts that say that backing up the /home directory is enough, but it has failed me once, and I don't see how that works. Does it store all my settings & apps, things like shellscripts I add to the /bin directory(am I even supposed to do that?), or changes i make when i edit stuff like /etc/sysctl.conf?
Sorry for my poor English, what I basically want is this How to make a disk image and restore from it later? except I don't use Wubi. I am wondering if hard links or lvm's can save my disk space & time. I do a lot of swiching languages back and forth, and it almost never goes back to what I originally had, especially input method.
As both a new linux user and a non-english speaker, any suggestions for terms I can use to google would also help me alot. Thank you.
(I tried lvm snapshots following instructions on askubuntu, and failed. I would like to learn what I did wrong in the future, but it seems that it is not intended for keeping multiple snapshots, so this is probably not a choice for me at the moment right?)
