\u00a1La nueva versi\u00f3n Proxmox Backup Server 3.4 ya est\u00e1 disponible! Cargada de potentes optimizaciones y mejoras, esta versi\u00f3n est\u00e1 dise\u00f1ada para que tus copias de seguridad sean mejores que nunca.
No dejes de leer nuestro art\u00edculo acerca de Proxmox VE<\/a>.<\/p>\n\n\n\n

La soluci\u00f3n de copias de seguridad para empresas permite realizar respaldos y restauraciones de m\u00e1quinas virtuales, contenedores y hosts f\u00edsicos, integr\u00e1ndose perfectamente con Proxmox Virtual Environment y permiti\u00e9ndote proteger de forma segura los datos cr\u00edticos de tu negocio.<\/p>\n\n\n\n

Algunas de las novedades destacadas:<\/strong><\/h2>\n\n\n\n
    \n
  • Rendimiento optimizado para la recolecci\u00f3n de basura (Garbage Collection)<\/li>\n\n\n\n
  • Selecci\u00f3n granular de instant\u00e1neas de respaldo para tareas de sincronizaci\u00f3n<\/li>\n\n\n\n
  • Respaldos m\u00e1s sencillos de hosts Linux arbitrarios gracias a una nueva compilaci\u00f3n est\u00e1tica del cliente CLI<\/li>\n\n\n\n
  • Mayor rendimiento en copias de seguridad en cinta<\/li>\n\n\n\n
  • Basado en Debian 12.10 (\u00abBookworm\u00bb), pero utilizando el kernel de Linux 6.8.12-9 como predeterminado estable y el kernel 6.14 como opci\u00f3n<\/li>\n\n\n\n
  • ZFS 2.2.7 con parches de compatibilidad para el kernel 6.14<\/li>\n<\/ul>\n\n\n\n

    Rendimiento optimizado para la recolecci\u00f3n de basura (Garbage Collection, GC):<\/strong><\/h3>\n\n\n\n

    Para mejorar la eficiencia del almacenamiento mediante deduplicaci\u00f3n, los datos de respaldo en Proxmox Backup Server se guardan como fragmentos (chunks). Cuando se eliminan instant\u00e1neas de respaldo, un proceso de GC identifica y elimina los fragmentos de datos que ya no se utilizan. La versi\u00f3n 3.4 optimiza este mecanismo de GC mediante la integraci\u00f3n de una cach\u00e9 que reduce el n\u00famero de actualizaciones costosas de metadatos. Aunque esto incrementa el uso de memoria, reduce significativamente el tiempo de ejecuci\u00f3n, logrando una recolecci\u00f3n de basura m\u00e1s r\u00e1pida y eficiente. Este sistema de cach\u00e9 se puede ajustar por cada datastore.<\/p>\n\n\n\n

    Selecci\u00f3n granular de instant\u00e1neas de respaldo para trabajos de sincronizaci\u00f3n:<\/strong><\/h3>\n\n\n\n

    Las copias de seguridad remotas son fundamentales para la seguridad de los datos. Por ello, Proxmox Backup Server permite configurar trabajos de sincronizaci\u00f3n para enviar o recibir instant\u00e1neas entre instancias remotas. Hasta ahora, los filtros de grupo permit\u00edan definir qu\u00e9 grupos se sincronizaban. En esta versi\u00f3n, se ampl\u00eda la funcionalidad para permitir sincronizar exclusivamente instant\u00e1neas que est\u00e9n cifradas o verificadas.
    <\/p>\n\n\n\n

    Compilaci\u00f3n est\u00e1tica del cliente de Proxmox Backup:<\/strong><\/h3>\n\n\n\n

    Aunque Proxmox Backup Server se integra estrechamente con Proxmox VE, su cliente de l\u00ednea de comandos tambi\u00e9n puede utilizarse fuera de este entorno. Esta versi\u00f3n incorpora un binario de cliente compilado de forma est\u00e1tica, lo que facilita la creaci\u00f3n de copias de seguridad a nivel de archivos en cualquier host Linux.
    <\/p>\n\n\n\n

    Mayor rendimiento en respaldos en cinta (tape backup):<\/strong><\/h3>\n\n\n\n

    Desde la versi\u00f3n 3.4, Proxmox Backup Server permite aumentar el n\u00famero de hilos de trabajo (worker threads) al leer fragmentos durante los respaldos en cinta, lo que puede mejorar significativamente el rendimiento en determinadas configuraciones.
    <\/p>\n\n\n\n

    \u00daltimas versiones de tecnolog\u00edas de c\u00f3digo abierto:<\/strong><\/h3>\n\n\n\n

    Esta versi\u00f3n se basa en Debian 12.10 (\u201cBookworm\u201d), pero incluye el kernel de Linux 6.8.12-9 por defecto y soporte para el kernel 6.14 como opci\u00f3n. Tambi\u00e9n incorpora ZFS 2.2.7<\/strong> con parches de compatibilidad para el kernel 6.14, ofreciendo mejor soporte para hardware reciente.
    <\/p>\n\n\n\n

    Integraci\u00f3n con Proxmox VE:<\/strong><\/h3>\n\n\n\n

    Proxmox Backup Server se integra perfectamente con Proxmox Virtual Environment. Basta con a\u00f1adir un datastore de Proxmox Backup Server como nuevo destino de almacenamiento en Proxmox VE.<\/p>\n\n\n\n

    Disponibilidad<\/h3>\n\n\n\n

    Proxmox Backup Server 3.4 ya est\u00e1 disponible para su descarga. Los usuarios pueden actualizar su versi\u00f3n actual o realizar una instalaci\u00f3n desde cero en un servidor f\u00edsico utilizando la imagen ISO y el asistente de instalaci\u00f3n. Las actualizaciones desde versiones anteriores pueden realizarse mediante APT. Tambi\u00e9n es posible instalar Proxmox Backup Server sobre Debian.<\/p>\n\n\n\n
