File Replication Service (FRS)
Definition - What does File Replication Service (FRS) mean?
File Replication Service (FRS) is a feature in Microsoft Windows Server which is a successor to the LAN Manager Replication service of Windows NT Server. It is used for the replication of the system policies and script by the Windows Server. This data is stored in the SYSVOL, or the system volume, of the server. It is stored in the controllers of the domain, and can be accessed by the client servers of the network. Distributed File System Replication Service is now quickly replacing File Replication Service.
Techopedia explains File Replication Service (FRS)
FRS is a service which allows the sharing of Group Policies and logon scripts to the domain controllers, from where they may be accessed by the users through the client servers. The executable file running the service is NTFRS.exe. This service can also be used to replicate files and synchronize the data of its domain controllers using a DFS. It is also able to keep data on multiple servers at once.
The synchronization process is quick and complete. As it initiates very important scripts and processes which are required for logon, the services have to be quick, efficient and dependable. This service fits all the requirements because it backs up all the data on different servers while replicating them. The sync service is very fast and any changes in the policies are instantaneously changed in the client’s data.
