Hi, Thanks for your answers. Le 07/08/2015 22:12, Michael Morgan a écrit : > Btrfs root, snapper, and python-dnf-plugins-extras-snapper have been a > godsend for me in this regard.

And conversion from ext4 does not seem worth the risk, for the moment. > http://snapper.io/ > http://rpm-software-management.github.io/dnf-plugins-extras/snapper.html The documentation says that snapper supports ext4 but only experimentally, do you have any feedback on the matter ?

I even saw there : https://wiki.archlinux.org/index.php/Btrfs_-_Tips_and_tricks#Automatic_snapshots_on_each_boot that one can configure automatic snapshots at boot which is not far from what you propose. I guess this is reproducible on Fedora and that would definitely be my preference. > Another option, which is still maturing and really intended now only > as a platform for deploying containers, is Fedora Atomic (rpm-ostree). > This is really where rollbacks are at, because updates are atomic, and > it deals with all the gory bootloader details.

That, seems to be way over my head and what I want to achieve as I just have one computer to manage. Le 08/08/2015 04:58, Michael D.

I actually went for redobackup : http://redobackup.org/ It has a web access as it runs on ubuntu, that's what convince me. So I will go for this for now, and I will update my system to btrfs next time I install. Le 08/08/2015 15:57, Heinz Diehl a écrit : > rsync -avxHSAX /source/ /target Heinz.. Try to catch up please.. Sorry ! I couldn't resist.. :) Seriously, I'm not sure that rsync, even executed with root privileges, will have access to all files and will be able to copy the entire /dev/sd[n] identically. Will it ? Thanks again to all ! ;) -- "One original thought is worth a thousand mindless quotings." "Le vrai n'est pas plus sûr que le probable." Diogene Laerce
