What is the best way to set up a large file server with a robust backup solution?

I am looking to set up a client with a file server with room to grow for about 5 years. They currently have a file server running Windows 2000 with 100GB of data.



I would like to set them up with 1TB of data storage or more. The catch is to set up a robust server with great performance and have a backup solution that doesn't require 200 tapes and allows for easy offsite storage.



Their current backup first backs up data to a stand-alone server, and then duplicates that to a series of REV disks. If we went up to 1TB or more of data storage, we would need about 20 to 30 REV disks. This is a solution that just won't work.

Yea all those answers are good but if people are too technical savy you can always look into an apple based NAS, you can easily fit 7TB of data in a 4-5U chassis. Apple has complete support for Active directory and Windows Domain use, infact you can even start an AD or Windows Domain using the apple server. I am not pushing for apple but we use it where I work and they look great and are flawlessWhat is the best way to set up a large file server with a robust backup solution?
If your going to have 1tb of storage, then you need a SAN or NAS. Otherwise Dell servers are very good. You may hear about how Dell sucks with their pc's, but there servers are very good. My company has 35 Dell servers and they are all very reliable.What is the best way to set up a large file server with a robust backup solution?
NAS is simpler for Storage, go for Sun solutions, expensive but very reliable and robust. You can use a dedicated connection to offsite storage if applciable and transfer the backups remotely.
