Difference between BRS and FRS

Business requirement specifications (BRS) and file replication solutions (FRS) are both essential for data management, but they serve different purposes. A BRS outlines the specific needs of a business, while an FRS replicates files between servers to ensure data security and redundancy. In this blog post, we’ll examine the key differences between BRSs and FRSs so you can decide which solution is best for your organization.

What is BRS?

BRS Business Requirement Specification is a document that outlines the specific requirements for a business or project. It includes a description of the business need, the expected results, and the necessary resources. The BRS is used to communicate the requirements to stakeholders and to ensure that all parties involved understand the scope of the project.

It is also used to assess the feasibility of the project and to develop a plan for its implementation. The BRS is an important tool for businesses and organizations of all sizes, as it helps to ensure that projects are completed on time and within budget.

What is FRS?

FRS File Replication Service is a system that replicates files and folders stored in a central location to other computers on a network. FRS was first introduced with Windows 2000 Server and is still used in Windows Server 2003, 2008, and 2012.

  • FRS uses the NTFS file system to replicate files and folders, and it can be configured to replicate specific files or all files in a specified folder. FRS also supports the replication of Active Directory objects, including user accounts, group memberships, and security settings.
  • FRS is typically used to replicate system files (such as DLLs and EXEs) to multiple servers or to replicate user data (such as documents and application data) to multiple client computers.
  • FRS can also be used to replicate files between servers in different Active Directory domains. FRS has been replaced by the Distributed File System (DFS) in Windows Server 2012.

Difference between BRS and FRS

BRS (Business Requirement Specification) defines the high-level business requirements for a product, service, or system. It is normally prepared by business analysts after consulting with stakeholders. FRS (File Replication Service) is a Microsoft Windows Server feature that allows files and folders to be replicated from one server to another.

  • BRS is about understanding the business needs and FRS is about replicating files from one server to another. BRS focuses on what the product, service, or system should do whereas FRS focuses on how the replication should be done.
  • BRS is a document that forms the basis for further development work whereas FRS is a software component that needs to be configured to perform file replication.
  • In conclusion, BRS and FRS are two different things. BRS is focused on understanding the business needs while FRS is focused on replicating files from one server to another. BRS is document-oriented while FRS is code-oriented.
  • BRS comes first in the development process while FRS comes after BRS in the development process. BRS can be used for products, services, or systems while FRS can only be used for replicating files from one server to another.

BRS may have multiple versions depending on the complexity of the project while there will only be one version of FRS. Finally, BRS may not be required for simple projects while FRS will always be required when replicating files from one server to another.


Although they share some similarities, BRS and FRS have important distinctions that can impact your business. Make sure you understand the differences so you can choose the right service for your needs.
