Tiene mal aspecto, pero aunque la primera opci\u00f3n en la que pensamos es la de atacar a nivel MySQL, dado que el entorno es muy est\u00e1tico y no ha habido cambios de configuraci\u00f3n en las \u00faltimas 24h, optamos por la v\u00eda r\u00e1pida e integrada en OVM, la herramienta de restauraci\u00f3n de MySQL de OVMM. Para ello, basta seguir la documentaci\u00f3n bastante clara y expl\u00edcita de Oracle que podemos ver\u00a0aqu\u00ed<\/a>. En nuestro caso, solo queremos recuperar a nivel de BD, por lo que no necesitamos ejecutar el paso n\u00famero 1.<\/p>\n
OVMM genera diariamente y de manera autom\u00e1tica, un backup de la BD MySQL en la ruta \/u01\/app\/oracle\/mysql\/backup<\/strong> (OVM 3.4). Vemos el contenido de este directorio en nuestro caso:<\/p>\n
