NetBackup using an out of band network

Created: 22 Apr 2013 | 1 comment

Just curious to see how many people run their backups over an out of band network.  My company still runs all the backups data over the same network as its production.  How many people still do this?  

 

Thoughts and comments are appreciated.

We use a mix. 

Handling two NIC - one primary and one for backup can be pain if operation isn't trained to handle the "deviations". E.g. server name may be srv1.acme.com but backup name may be srv1.bck.acme.com. Now mix this with a little DNS, SAP, Oracle and static routes (sometimes forgot) and you can have one big confusion that will take you days to sort out.

So we try limit the use of dual homed hosts to customer that require it. That said we do have a backup core where backup traffic from the default gateway is separated from ordinary traffic. This core is built with 40GB link between switches and utilize heavy port filtering instead of fire walls because of the high bandwidth.

Assumption is the mother of all mess ups.
