There are many ways to backup an Ubuntu installation. The most important thing about backups is to develop a <emphasis>backup plan</emphasis> consisting of what to backup, where to back it up to, and how to restore it.

Existen muchas maneras de realizar un respaldo de una instalación Ubuntu. El aspecto más importante sobre los respaldos es definir un <emphasis>plan de respaldo</emphasis> que consiste en «qué respaldar», «donde respaldarlo», «donde guardar el respaldo» y «cómo restaurarlo».

One of the simplest ways to backup a system is using a <emphasis>shell script</emphasis>. For example, a script can be used to configure which directories to backup, and pass those directories as arguments to the <application>tar</application> utility, which creates an archive file. The archive file can then be moved or copied to another location. The archive can also be created on a remote file system such as an <emphasis>NFS</emphasis> mount.

Una de las formas más simples de hacer una copia de seguridad de un sistema es usar un <emphasis>script del shell</emphasis>. Por ejemplo, un <emphasis>script</emphasis> puede usarse para configurar qué carpetas copiar y usar esas carpetas como argumentos de la utilidad <application>tar</application> creando un archivo tar. El archivo puede luego moverse o copiarse a otro lugar. El archivo puede también crearse en un sistema de archivos remoto montado, por ejemplo, por <emphasis>NFS</emphasis>.

The <application>tar</application> utility creates one archive file out of many files or directories. <application>tar</application> can also filter the files through compression utilities, thus reducing the size of the archive file.

The following shell script uses <application>tar</application> to create an archive file on a remotely mounted NFS file system. The archive filename is determined using additional command line utilities.

El siguiente script de shell usa <application>tar</application> para crear un archivador en un sistema de archivos NFS montado de forma remota. El nombre del archivador se determina usando comandos adicionales.
