We are using arcserve to backup all of our centrally managed servers. We are backing up several Win NT and Win2K boxes as well as 3 unix and 4 Novell servers. The Unix and Windows servers backup up at somewhere between 300-400Mb/min but when we get to the Novell boxes the backup rate drops to 25Mb/min. We have looked at several items on the Novell box including several patches and the new TCP/IP stack, but to no avail. Anyone have additional ideas for us???
