[Networker] SUMMARY : Duplicated save sets during full backup

Hi everybody, 

First, thanks to Howard Martin and Robert Maiello for their replys... !

I was indeed on the right track suspecting the firewall... I later found 
the following documents on the legato support site : legato20127 (also 
LGTpa33177, LGTpa60016).

So the firewall guy cranked up the timeout value (for the networker ports 
only) from 3600 seconds to 9000 seconds. I did my full backup this morning 
and voila! No more duplicated save sets !

Thanks !

        Objet : Duplicated save sets during full backup


Hi, 

I recently added a few clients in a new group to my Networker server 
(W2K3, NW 7.1) and I began to notice a strange behavior with 2 of my 
groups (the new one, and an old one). 

Some save sets are backed up twice, even 3 times ! So a 15Gb backup takes 
some ~30Gb instead !!!

The one thing that those two groups have in common is that they both 
backup through a firewall (not the same one, but both firewalls are the 
same [Checkpoint FW-1 NG R55]).

The only thing I'm seeing in the firewall logs are dropped packets because 
they are "out-of-state" (ACK sent before SYN, and such...)... 

Has someone on the list seen a behaviour like that ? 

Any help is greatly appreciated...

Thanks !
