Type "screen [-d] -r [pid.]tty.host" to resume one of them.

Möchte mein System neu installieren und diese dann wieder herstellen.

Kann man die irgendwie sichern?

Normalerweise überlebt screen (und alles andere) nicht mal einen Reboot, von einer Neuinstallation ganz zu schweigen.

Es gibt dann so Ansätze wie http://criu.org/ aber das würde wenn überhaupt die alten Versionen der Prozesse herstellen... und ich hab keine Ahnung ob das mit Sockets, Screens usw. funktioniert.

Wenn du in den Screens einfach nur irgendwelche Dienste laufen hast wäre ein Script das diese Dienste einfach wieder neu startet vielleicht der bessere weg.
