asked on
subnet mask and backup
I am setting up a backup solution for my client...
what I am would like to do is set up my backup server on a different subnet mask than the that of my normal business traffic so that I can track the the network utilization used during the backup process since the backup server will be touching several servers/workstations.
1. is this possible
2. can you have 2 differnet subnet masks on the same system
3. if yes to 1 & 2, can I still use the same ip adressing scheme on the backup subnet
the environment is MS with 2003 servers running ads and xp workstations. the network layout is very flat with all systems home run'd to the same switch.

so what you suggest is on the second card that I use different ip addresses and subnet that are similar to the one that is used on the backup system?

and you as well...you are a big help!
2. Yep, each network card will have its own IP address and mask.
3. I would strongly advise against it. Whilst you can bridge across the two cards it can be problematic
Many sites now want to have a different backup infrastructure so it does not pass traffic across the main backbone. A frequent method is to put secondary cards in each of the servers concerned to make a small network this way.
