Just checked again. Yes, even on a full backup no data is being written to
disk until after over an hour of making "estimations" (sais Job
Tracker). A tape is
mounted all this time but no bits are send to it until Netbackup is
finished estimating.
We didn't have this problem 6 months ago (we were at NBU 3.4 then).
Thanks,
Ruben
