But you can recompile a second set of amanda programs that listens on another set of service ports that do not confict with eachother: ./configure --prefix=... --with-testing=tst and then define a second set of services in /etc/service with the suffix "tst": amanda-tst10090/udp kamanda-tst 10091/udp The feature was designed to be able to test amanda without interfering with the production run, but you could just as well give it a meaning ful name in your context, like --with-testing=eth1, listening on service amanda-eth1. Then the amanda on host bk0, compiled with standard settings communicates to clients listening on port 10080, and host bk1, compiled with --with-testing=eth1 backs up to possibly the same clients but using programs listening on port 10090. Each client needs both set of programs installed, in a different directory. This all said, I still don't understand why you want to do this actually. -- Paul

The "two amanda jobs" part is just having two configurations with two disklists and running them in parallel: 01 23 * * 0-5 /home/amanda/bin/config0 01 23 * * 0-5 /home/amanda/bin/config1 The "two ethernet cards" part is a little trickier, and is a properly a network administration question, not an Amanda question. :-) If: You have two routed subnets, The amanda server is dual-homed (i.e., has two hostnames), All DLEs in config0 are on subnet 0, all DLEs in config1 are on subnet 1, ...then it's trivial and just works. If you're one big switched LAN, and your switches are VLAN-capable, and you have control over the VLAN organization, you can do essentially the same thing. If you're one big switched LAN, and you can't do VLAN, then you try to find out if your server and switch are capable of trunking. -- Jay Lessert [EMAIL PROTECTED] Accelerant Networks Inc.

multiple ethernet cards
Is it possible to run two amanda jobs at the same time on different ethernet cards. I have a machine that I am planning to use to backup my Win2k users. The data will be backed up to one of two partitions. Would it be possible to run Amanda jobs on different ethernet cards that backup to different partitions? Some users will back up to bk0 via eth0 and others will back up to bk1 via eth1. I am asking the question because I thought that I had read some place that you can ony run one Amanda job at a time.
