How to setup Branch Cache in Windows Server

Branch Cache certainly provides fast access to files and data in branches by caching content from a central server, reducing the need for constant transmission of data over the network. In addition, it has two modes of operation:

Distributed Cache Mode: For this the client stores a cached version of the requested BranchCache-enabled files and serves as a distributed cache for other clients requesting the same files.

Hosted Cache Mode: In this designated servers in specific locations act as a cache for files requested by local clients. That is, instead of retrieving files from a remote source, the cache server serves the content on your behalf.

How to setup Branch Cache in Windows Server

BranchCache is a valuable technology in Windows Server that significantly improves network performance in branch offices with limited bandwidth connections. By caching frequently accessed files locally, BranchCache reduces WAN traffic and enhances user experience. 

1. Identifying BranchCache Requirements:

Feature vs. Role Service: The first step involves determining your specific needs. The BranchCache feature suffices for caching general files, while the BranchCache for Network Files role service caters to file server caching scenarios. Choose the appropriate option based on your file access patterns.

2. Server Preparation:

Server Manager: Utilize Server Manager to install the chosen BranchCache component. Navigate to the "Add Roles and Features" wizard and select either "BranchCache" or "BranchCache for Network Files" depending on your selection in step 1.

3. Group Policy Configuration (Optional):

Active Directory Integration: If you leverage Active Directory, creating a Group Policy Object (GPO) offers a centralized approach to deploying BranchCache across numerous branch office servers.

GPO Settings: The GPO can be configured to manage various BranchCache settings, including:

Enabling BranchCache functionality on member servers.

Establishing cache size limitations.

Defining caching behavior for specific file types.

4. Configuring BranchCache on Branch Office Servers:

Server Manager Access: Launch Server Manager and locate the "BranchCache" configuration options.

Distribution Group Membership: Configure BranchCache servers to join a distribution group. This enables them to discover each other and facilitate content sharing within the cache network.

5. Folder Permissions (For Network File Caching):

Read Permissions: If you're using BranchCache for Network Files, ensure that users possess the necessary read permissions on the folders you intend to cache. This allows for proper file access from the local cache.

6. Verification and Monitoring:

Event Viewer: Utilize the Event Viewer to monitor for any errors or warnings during the BranchCache configuration process.

Performance Tracking: To assess BranchCache's effectiveness, track network traffic and file access times. Reduced WAN usage and faster file access indicate successful implementation.

Additional Considerations:

Firewall Rules: Configure firewalls to permit communication on ports required by BranchCache for seamless operation.

Data Deduplication: Consider enabling data deduplication to optimize storage space utilization within the BranchCache cache. This is particularly beneficial for caching redundant data.

We hope that with these steps, you can effectively deploy BranchCache in your Windows Server environment. This will lead to better network performance, lower bandwidth consumption, and a more responsive user experience at your branches.
