Hi Udo,

thank yout for your reply.

From netstat -i I can see that the loopback adapter (lo0) ist being used for
this kind of backup. So all should be ok.
Any other recommendations to speed up backup operations via shared memory?
The elapsed processing time is close together for backing up via LAN, SP
switch or shared memory.

regards
Rainer
