Copia de seguridad o backup

como puedo crear una copia de seguridad completa en ubuntu budgie? es que no trae programa instalado y en la tienda de software no me permite buscar para instalar. me toca desde la terminal.
gracias

Hi,

sorry I don’t read much spanish, write it even less, so these are suggestions about « backup » :

…many backup tools are available in « normal / default » Ubuntu repositories.

Now you want maybe something like an .iso image of your disk⋅s partitions ?
Have a look then at gnome-disks utility, and gparted : both can write an .iso image ( a clone ) of partitions. Clonezilla also.
