We are in the process of design phase of our backup "architecture." We are a manufacturing company and have approximately 50 sites (95% frame-relay, hub and spoke model, with at least four hub sites). Most of the traffic crosses the "IT data center" to get to other sites from the hubs.
We are debating the pros and cons of central over the WAN back (256K, 0 CIR PVCs for the majority of the links) or go with each HUB doing central backups or each site doing its own backup.
I like the idea of centralizing backups to an IT data center. We have looked at a few vendors (NSI double take, CommVault to name a few) and they all "pitch" that it is a great idea. However, I have to make a business case and convince my boss with why it will be a great cost saving, low managing idea.
Any white papers, best practices, etc. or advice is greatly appreciated.
W. Curtis Preston's response:
With that many sites, I'd be looking for a centralized backup system too! First, I will say that I think centralized backup is a good thing, especially with that many sites. Its biggest advantage is that it significantly reduces administration costs. The other big advantage is that you're already providing off-site, disaster recovery type backups if you're using an alternate site as your backup. There are a number of ways you can do this and it depends heavily on the infrastructure that you have, or are willing to purchase. Here is a quick list of some options. Which option is right for you will depend on which type of hardware/software combination you have.
