How to fully backup ubuntu?

Question

linux

Hello, lately I like to experiment with my ubuntu 14.04, and because of this, sometimes I cripple the OS (I myself sometimes don’t understand how, but the fact is).
And, how can you completely backup the current state of ubunta?

Answer 1

Probably clonezilla, as advised earlier.
And you can, for example, using the dar program .
Example

Answer 2

- clonezilla
- backintime.le-web.org
And a lot more, including the built-in Déjà Dup

Answer 3

Experiments can be carried out on a virtual machine.
Created a virtual machine, made a copy. They messed up the virtual machine, launched a copy.
This will turn out much faster than deploying backups.
qemu-kvm virt-manager packages

Answer 4

Alternatively, use xfs.

Answer 5

Try the BTRFS file system, you can take snapshots of the entire file system as often as you like and very quickly / cheaply, you can even automate, there is a tool . But this is also a bit of an experiment)
