File Share Synchronization

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

Modern File Synchronization Needs

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.

Challenges of Traditional File Share Replication

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:

Conflict Resolution

Conflicts need to be managed across locations during concurrent access.

Permission Sync

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

Remote Offices

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

Change History

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

Version Control

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

Mobile Access

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

Feature Highlights of File Share Synchronization

Conflict Resolution

CentreStack leverage version controls and centralized arbitration to resolve conflicts.

Permission Sync

CentreStack syncs NTFS folder permissions to a centralized repository.

User Identity Sync

CentreStack syncs Active Directory users to a centralized repository.

On-Demand Sync

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

Time Stamp Sync

Meta data like file modification and creation times are preserved after sync.

Binary Differential Sync

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

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.


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.
