Running Large Backups over an MPLS Network

Unanswered Question

We are opening up a second data center at my organization. The location is about 60 miles from our primary data center.


At our primary data center we use an MPLS network for our WAN. We have ll remote locations on our WAN and we have a DS-3 that connects to our primary data center.


At our new second data center we will connect it to the MPLS network.


Do you think we should run our backups between the 2 data centers across the MPLS or do you think we should order a seperate private line or ethernet type service between the 2 data centers? All back ups from our primary data center will continually move across the network to our new secondary data center.


Do you think MPLS is a good technology to run large back ups across? Is it reliable enough

Hi


In case of backup DC, it is also recommended to have the backup link for replication. If you are planning to add SAN, it would help to save the wan bandwidth.

MPLS is a highly scalable, protocol agnostic, data-carrying mechanism. We have a similar eviroment and what we have is a fully mesh MPLS cloud giving us the ideal redunadancy we need. Also each datacenters coonecting to multiple POP. With this can of design, we dont need addtional backup link.

"Do you think MPLS is a good technology to run large back ups across?"


Sure.


"Is it reliable enough"


Depends more on your MPLS provider than the technology itself.


Two issues that may be more important to you vs. how "reliable" MPLS is, might be cost of bandwidth vs. other technologies or sharing the MPLS bandwidth with non-backup applications. The latter would depend much on what QoS that might be available to you to insure your backup traffic doesn't adversely impact non-backup traffic.
