Should I create a VLAN to segment backup data or not

I am in the process of trying to work out the benefits of setting up a VLAN to allow our virtual machines to backup across it as opposed to having our NAS drive directly attached to our physical server.

We are a small company with only a handful of users. We have a physical server that runs two virtual servers with a NAS server so we can perform backups of our data to it. There is low traffic across our network and we will run the backup out of hours using Backup Exec 2014.

I want to try and find out if there is any particular reason to go ahead and create a dedicated VLAN and run the backups across it as opposed to just directly connecting the storage device to our internal network?

Any advice would be very helpful, thanking you in advance.

I would not have thought so, keep your configuration simple!

You state low traffic, and backups conducted at night, so I do not see the benefits of a VLAN, and all the configuration changes required.

The only benefit I can see is to the Administrator, you can then put it on your CV!

Because we are running two virtual servers would there be any benefit from a performance point / speed of backup if we were to use VLANs?

Not that you are going to notice, no.

Physical separate dedicated network - maybe, but it depends where the bottleneck is, reading and writing data is probably the bottleneck.

and if you have currently look at network performance, if you have reached maximum utilisation for the LAN link.
