[pauln (Paul Nate)]

Hi guys, how can I backup Discourse when the backup has failed.

I have over 90GB of free space.

@pauln

ruby/2.0.0

¿Es esta una instalación realmente antigua?

@pauln

EXCEPTION: No space left on device

@pauln

Tengo más de 90 GB de espacio libre.

Parece que el disco donde Discourse tiene montado el volumen no cuenta con este mismo espacio.

[neounix (Dark Matter)]

@pauln

Hola a todos, ¿cómo puedo hacer una copia de seguridad de Discourse cuando la copia ha fallado?

Hola @pauln

En tu último tema, mencionaste que estabas usando un VPS muy antiguo de Linode con Debian 7.5.

Este es un problema fácil de resolver si lo abordamos paso a paso.

Para comenzar, por favor publica la salida del siguiente comando, para que podamos ver un informe del uso del espacio en disco de tu sistema de archivos:

df

Además, proporciona un resumen del uso de tu espacio en disco de la siguiente manera:

cd /var/discourse/shared
du -sh *

Este es un problema fácil de resolver. ¡No te preocupes!

---

Nota: También estamos asumiendo que estás preparándote para migrar a un nuevo VPS, según tu tema anterior.

Referencia al post anterior de @pauln sobre esta instalación:

“Your Docker installation is not using a supported storage driver.”

Aquí tienes un resumen de la salida de df

Aquí tienes un resumen de du -sh *

Sí, voy a migrar a un NUEVO VPS, pero primero estoy intentando hacer una copia de seguridad antes de mudarme al nuevo servidor.

[neounix (Dark Matter)]

@pauln

Sí, voy a migrar a un NUEVO VPS, pero estoy intentando hacer una copia de seguridad primero antes de pasar al nuevo hosting.

Sí, lo sé. Estás haciendo lo correcto y un buen trabajo.

Probemos con una estrategia diferente.

¿Puedes realizar una copia de seguridad correctamente sin incluir las subidas?

Si es así, simplemente podemos tomar (1) esa copia de seguridad y (2) un archivo tar separado del directorio de subidas y lograr lo que deseas.

Por lo tanto, por favor intenta hacer solo una copia de seguridad sin las subidas (el botón del medio a continuación); seleccionando esa opción en la ventana de copia de seguridad; y responde con el resultado.

Si eso falla, intentaremos hacer la copia de seguridad de la base de datos manualmente desde la línea de comandos , lo cual es bastante sencillo y funcionará, estoy bastante seguro (lo hacemos todo el tiempo y rara vez restauramos desde la interfaz gráfica).

Manually create and restore Discourse backups

As discussed below, a warning for newbies: this is an advanced method! there is an automated, web UI way to restore from backups at /admin/backups which is so much easier. with the method below, no automatic backup is kept of the /var/discourse/containers/app.yml file which contains essential SMTP credentials and SSL customizations. Keep a copy of this offsite whenever you change it. If you are using digital ocean, keep frequent snapshots of your droplets - preferably before each time you run .…

Nota:

Lo que decidas hacer @pauln, por favor no destruyas tu VPS existente que ejecuta Debian 7.5 y Discourse hasta que hayas instalado correctamente otra instancia de Discourse (y la hayas restaurado y probado) en tu nuevo VPS.

[pauln (Paul Nate)]

@neounix

Así que, por favor, intenta hacer una copia de seguridad sin las subidas (el botón del medio a continuación); seleccionando esa opción en la ventana de copia de seguridad; y responde.

También falló. ¿Entonces nuestra siguiente opción es hacerlo a través de la línea de comandos?

[neounix (Dark Matter)]

@pauln

También falló. ¿Nuestra siguiente opción es hacerlo mediante línea de comandos?

Sí, señor.

Eso debería estar bien.

Háganos saber cómo le va o si necesita más ayuda. Tendrá que:

1. realizar una copia de seguridad manual de la base de datos PostgreSQL de Discourse; y
2. crear un archivo manual de la carpeta uploads.

Las instrucciones para crear los archivos manuales son correctas en la referencia anterior.

Sin embargo, cuando probé esas instrucciones hace un momento, no pude escribir en el directorio compartido desde dentro del contenedor, así que primero hice esto (asumiendo que su instancia es app):

docker exec -it app bash
mkdir /shared/mybackups
chown postgres /shared/mybackups

y cambié todas las rutas para escribir en /shared/mybackups en lugar de /shared, pero es posible que usted no tenga ese problema.

Espero leer pronto sobre sus avances.

[pauln (Paul Nate)]

¡Hola! Estoy muy agradecido por tu ayuda. Funcionó, me mudé a un nuevo VPS y ahora funciona bien

[neounix (Dark Matter)]

¡Noticias maravillosas y gran trabajo, @pauln.

¡Felicidades por tu actualización exitosa!
