File Share Synchronization 

File share sync with mobile remote access.
Simplify remote access and collaboration with a centrally managed cloud file server for multiple branch offices.

Modern File Synchronization Needs Mobile Access

File synchronization gives the impression that files are always available when needed, encouraging mobility and productivity for remote employees. CentreStack provides a solution that synchronizes file shares with cloud storage, creating a unified directory structure for multiple branch offices. Most conveniently, mobile remote access and secure file sharing capabilities are added on top of the file share sync. 

Are you deploying Azure File Sync?

You must have read the "Deploy Azure File Sync" technical document for about 4000 words. Have you ever wondered why is it so difficult to setup file share sync there? 

Maybe a better question to ask is, what is the end-game after deploying the Azure file sync? Does it give your employees web browser file access? Does it give your employees mobile remote access to file shares? Do you simply use it as a backup tool?

Azure File gives you a network share over the Internet. However it is not as easy to use as a OneDrive or other Dropbox-like services.

Challenges of DFS

Microsoft DFS (Distributed File System) is most commonly used for file share replication (DFS-R, really). However, DFS-R was really designed to work on local area networks with Active Directory and can be problematic when replicating over wide area networks. When replication is required among branch offices, VPNs (virtual private networks) are more typically used. However, VPNs also tend to generate lots of issues. The bottom line is that both services render replication unreliable.

DFS-R is particularly bad at managing conflicts during bi-directional synchronization and there are many missing features such as version control, audit tracing, and file change histories that are not part of the DFS replication.

Other common problem areas include:


Conflicts need to be managed across locations during concurrent access.


File permissions are an important part of file information and need to be synchronized.


Businesses are protected by firewalls and forced to depend on difficult to manage VPNs for remote office synchronization.


As files replicate to multiple locations, change control becomes increasingly difficult.


Version Control is not a built-in feature for file shares.


Remote and Mobile Access is not a built-in feature for traditional file shares and DFS-R doesn't help with mobile access.

File Sync and Share Designed for
Windows File Servers

Sync File Server Shares to Cloud and Use it like a Dropbox!

With CentreStack, the end result of a file share sync is that on-premise file server shares are synchronized into cloud storage service (including Azure Blob Storage) and employees can use mobile phones, remote devices and web browsers to access files and folders with their existing active directory credentials.

Basically your file servers after file share synchronization, becomes a Dropbox-like or a OneDrive-like file sharing service.

File Share Synchronization Feature Highlights

On top of the file server synchronization, CentreStack adds mobile remote access features, including desktop mapped drive, mobile applications and web browser based file manager. Secure file sharing features such as web-link sharing and secure data room are also added. At the end, it is a file sync and share solution that focuses on delivering cloud enablement to Windows file servers.

Conflict Resolution

CentreStack leverage version controls and centralized arbitration to resolve conflicts.

On-Demand Sync

CentreStack presents a full folder structure without actually downloading files until the moment they are accessed.

Binary Differential Sync

CentreStack leverage rsync to detect smaller sections of changes in a file and syncs accordingly.

Permission Sync

CentreStack syncs NTFS folder permissions to a centralized repository.

Folder Permissions

Define different permissions for folders at different levels of the directory structure or inherit from NTFS permissions directly.

Secure Data Room

Web based secure data room allows view-only access to shared folders with download disabled.

User Rights

From internal Active Directory users to external clients and partners, you can define user rights for folder sharing.

Version Control

Shared folders are put under version control and notifications are available for users subscribed to the folders.


CentreStack integrates with Office 365 for web-based co-editing and co-authoring for files inside the shared folder.

Large Folder

Use Outlook integration to share large folder or files as web links via email.

Link Sharing

Convert shared files and shared folders into web links for direct access over web browsers.

Mobile Application

Access shared files and shared folders from mobile devices such as from iPhone or Android phone.

Cloud File Server Use Cases

Synchronizing local file shares from multiple branch offices into a centrally managed cloud file server simplifies access and collaboration using HTTPS/SSL and other secure transfer protocols. And for business continuity, files are under version control in the cloud with locally cached copies at each branch office.

Multiple Branch Offices

Move File Server to Cloud

Move file server to cloud seamlessly


CentreStack synchronizes local file shares to the cloud for business continuity and for centralized secure cloud-based access.

Business Continuity 

Syncing local file shares to the cloud with version control improves business continuity for local and remote file servers in branch offices.

Mobile Access

Simplify remote and mobile access by synchronizing local folders to centralized cloud storage.

Branch Office Productivity

 Normally, it is not easy for branch office employees to access files from headquarters or for employees in the main office to access branch office files. But once all files are synchronized to a centralized cloud repository, access is simpler and more secure.

Reduce VPN Dependency

VPN file sharing can be avoided since files are now in the cloud, syncing in real time with on-premise file servers.

Version Control

All file changes can be managed and monitored with built-in version controls.

Audit Tracing and History

Audit traces and file change histories are available for file shares that have been synchronized.

Retire File Server

Once the file shares are synchronized with cloud, local file servers can be retired, if so desired.

Replace File Servers

Once the file shares are in sync with cloud, local file servers become gateways that can be easily replaced with newer servers or retired.
