Die Ver\u00f6ffentlichung des CRIU 4.0-Tools (Checkpoint and Restore In Userspace) erm\u00f6glicht die Speicherung und Wiederherstellung von Prozessen im Benutzermodus. Das Tool erlaubt es, den Zustand eines oder mehrerer Prozesse zu speichern und dann die Arbeit an der gespeicherten Position fortzusetzen, auch nach einem Neustart des Systems oder auf einem anderen Server, ohne vorhandene Netzwerkverbindungen zu unterbrechen. Der Projektschl\u00fcssel ist in C geschrieben und steht unter der GPLv2-Lizenz. CRIU wird in Container-Verwaltungssystemen wie OpenVZ, LXC\/LXD und Docker verwendet. Die erforderlichen \u00c4nderungen f\u00fcr die Nutzung von CRIU sind in den Hauptkern von Linux integriert. <\/p>\n
Die Anwendungsbereiche der CRIU-Technologie umfassen die Gew\u00e4hrleistung von Betriebssystem-Neustarts, ohne die Kontinuit\u00e4t langlaufender Prozesse zu st\u00f6ren, die Live-Migration isolierter Container, die Beschleunigung des Starts langsamer Prozesse (man kann die Arbeit von einem nach der Initialisierung gespeicherten Zustand beginnen), Durchf\u00fchrung von Kernel-Updates ohne Neustart der Dienste, das regelm\u00e4\u00dfige Speichern des Zustands langwieriger Rechenaufgaben zur Wiederaufnahme der Arbeit im Falle eines Absturzes, Lastenausgleich auf Knoten in Clustern, das Duplizieren von Prozessen auf ein anderes Ger\u00e4t (fork auf ein entferntes System) und die Erstellung von Snapshots von Benutzeranwendungen w\u00e4hrend des Betriebs zur Analyse auf einem anderen System oder f\u00fcr den Fall, dass weitere Ma\u00dfnahmen im Programm r\u00fcckg\u00e4ngig gemacht werden m\u00fcssen. <\/p>\n
