How to do a FULL system backup [duplicate]

Solution 1:

You can use Deja-dup for this. If you want to just backup all of your files, then you just have to set Deja-dup to backup your entire system. Make sure the Deja-dup does not backup your backup location or it will run into problems. If you are backing up to an external hard drive it will probably be mounted under /media/$USER.

I would recommend creating a system image because it saves all of your partitions and can be used to do a full system restore. It is common practice to do small backups of your home directory every day and then every week create a new system image. This way if your system gets breached, you can just restore a previous system configuration without worrying about your system getting screwed up.

Solution 2:

Use clonezilla on live CD/USB, its free and powerful. With this you'll be able to fully backup/restore disks/partitions including OS, userdata, etc..
