Backup de disco moribundo
Hola lista,
recientemente he notado que mi disco duro hacía cosas raras, así que
le he pasado un smartctl [1] y me ha confirmado que está en Pre-fail.
Dado que en este disco tengo tanto el sistema operativo (stable) como
los datos (/var, /home, ...) me gustaría encontrar la forma más
eficiente para hacer un backup de lo que es propiamente el sistema
operativo (programas, librerías...).
Con los datos (y /etc) no debería haber problema porque los tengo
copiados fuera.
Pero me gustaría mantener el mismo software y versiones que tengo
ahora mismo. Para ello he pensado en hacer:
copia de mi sources.list
# dpkg --get-selections > software.txt (para obtener lista de
programas y versiones)
volcado de mi sources.list
# dpkg --set-selections < software.txt (para hacer un volcado del
listado anterior)
# aptitude update
# dselect (para instalar/desinstalar el software)
Os parece buena ésta forma? Tenéis alguna sugerencia de mejora?
Muchas gracias y saludos.
