I am doing backup with onbar. I have also set my alamrprogram to
backup the logical logs using ontape -a.
The problem is that the onbar tries to backup the current logical
using onbar and it takes ages!!!
Is there a way to solve this???
I run out of logical logs if I have many data modifications while the
onbar is slowly (+ 2 hours) backuping THE logical log.
Thanks in advance.
