The issue that small DLEs are always full dumped is not that problem, because we are talking about some Megs /etc and some files in /root... The problem are the big ones. Should I split the big DLEs up into handsome parts, so that most of them are nearly the same size? This also leads me to the question regarding the dimensions of tape_length and splitsize and so on a asked Brian in a posting above: "Should I go for tapes with the length of the largest DLE (+ some GB spare)? Or should the tapes be smaller and should I use tape_splitsize and runtapes as mentioned in my last post?" > There are parameters that control how many total simultaneous dumps max > and how many simultaneous from one client max.

If no, do you allocate the vtapes over all disks? Thank you very much! /Thomas
