Replication with NAS or SAN?
The goal.
Primary: Replicate data from 2 branch offices and the main office to a weatherproof offsite facility for disaster recovery.
Secondary: Eliminate branch office tape backups by utilizing the replicated data to perform the backups from. Utilize snapshots for daily backups.
The setup.
3 Servers, 3 office location, Windows server 2k3, Voice/data Integrated T1 connections, VPN between all offices. Exchange maybe added at some point when it grows out of being simply a groupware package. No SQL with no plans on needing SQL currently.
I have looked at many alternatives, and at this point I need to know if spending the extra $$ for a Compellent Storageworks 3.5 or Dell/EMC SAN is worth it, or simply going with a NAS using Symantec Replication Exec or Xosoft Doubletake is the better more cost effective solution.(the Dell/EMC SAN would be running the replication exec or doubletake software anyway).
I really did like what I saw from Compellent, but I need more than that to justify the extra expense of a SAN solution over a NAS solution.
Any help greatly appreciated.

Storage
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

I have looked into into internet based replication/backup, but if we backup/replicate all the data we need to it adds up quickly to the inital capital investment of the NAS or even the SAN.
We currently backup to tape at all office location, problem with that is sometimes the remote offices do not follow procedures because I have to depend on "Joe technology user" to do the backup. As for the value of the data, we are an engineering firm and most of our work is the data. If we can not get to the data then work pretty much grinds to a halt.
I am going to check into MS DFS, if it handles replication well without killing our bandwidth then that could be an option.
What we want is to have a complete copy of our project data from all offices available to us should any disaster happen. We are willing to work with a 1 day old copy of data should we need to replicate after hours should bandwith be a problem with active replication.
