Cloud File Server Features

File Share Migration

You want to migrate a local file server to the Cloud. You are thinking about migrating to SharePoint and OneDrive, but the SharePoint Online limitations hold you back. What are the other options available?

Did you run into issues with SharePoint?

SharePoint Online is a part of the Office 365 offering. The benefits encourage businesses to migrate their file server to SharePoint online, thus saving the cost of maintaining a local file server.

However, there are several limitations you need to know before you start the SharePoint online migration journey. It may not be the right solution for you if you run into these issues. 

  • 5,000 item limit in a document library
  • 10,000 item sync limit for the OneDrive client
  • NTFS permission reorganization requirements
  • Maximum name length limitations
  • Prohibitive costs of data reorganization
  • 93 day recycle bin threshold
  • Lack of support for legacy application data (databases, etc…) 

Are you familiar with these SharePoint Online limitations?

  • 5,000 item - When you have a large number of items in a document library, the performance degrades to the point that it becomes unusable. 
  • 300,000 item - This is the limit on the number of documents users can sync using the OneDrive sync client. Performance starts to degrade.
  • 400 Character URL Limit - The URL path for all files and folders must be 400 characters or less (and no more than 400 characters for any single file or folder name in the URL). 

There are other cloud storage services without SharePoint limitations.

If you are running into file share migration issues with SharePoint Online and OneDrive, other cloud storage services are a better fit for file server migrations. The most notable is Amazon S3 (Simple Storage Service) and Windows Azure blob storage. If you have a large folder structure and use PhotoShop, InDesign, and AutoCAD applications, using Amazon S3 or Windows Azure blob are better choices.

Do you wish you can pick the final cloud destination for your local file share migration? 

What about Azure Files and Amazon FSx?

Azure Files and Amazon FSx for Windows File Server are two other choices for file share migration. However, these two services often show up in the context of a "Windows workload," which means used by Windows File Servers as a "workload" data repository for Windows applications. These two services are friendly to Windows applications that require an NTFS file system with SMB protocols. However, these two services are not end-user-friendly.

For example, it is not easy to provide a set of user credentials and login to these services, and use them as if they were from an internal file server network share.

You can pick a final destination in the Cloud!

Cloud File Migration Solution

A solution that adds iPhone application, web browser interface, Windows mapped drive, and Mac Finder volume to Amazon S3 buckets and turns Amazon S3 into a corporate cloud file server solution. Popular final cloud destinations include Windows Azure blob storage and other Amazon S3 compatible services. You can pick a final destination in the Cloud from these choices.

Remote Access

Combines on-premise file servers and Amazon S3 for secure remote access without the need to use a VPN.

Disaster Recovery

Leverages Amazon S3 as a central cloud file repository with version control, file change history and audit tracing to provide business continuity for file servers on-premises.

Mobile Sharing

The solution uses Amazon S3 storage in the Cloud for secure mobile file sharing from a web browser or mobile applications.

Cloud Migration

Sets up a hybrid deployment between local file servers and Amazon S3 storage that can be seamlessly converted to AWS only later.

Migrate file shares to the cloud or keep them on-premise! Either way, CentreStack combines Windows security with cloud access, mobile sharing and web-based collaboration features.

Cloud Drive Mapping

Drive Mapping is an essential feature for online file access. It is easy for end-users to access files and folders over the Internet from within a mapped drive with drag and drop capabilities.

Global File Locking

File Locking is a vital feature for online file access and team collaboration to eliminate conflicts. End-users need to control global concurrent online access to files by using file locking to maintain consistency.

Secure Mobile Access

Did you spend many hours troubleshooting VPN links? Did both your employees and the IT support team lose productivity due to down VPN links? VPNs are complicated; there is a better way!

Why CentreStack?

Backed by years of file server cloud enhancement with Amazon S3 and Windows Azure blob storage, CentreStack provides a file server-friendly collaboration platform focused on keeping your data private, secure, and under your control. Perhaps more importantly, the user experience is simplified. Good usability prevents the hard temptation for users to subvert any complex security measures to use ad-hoc methods.


Keep Your File Shares On-Premise

Prefer to keep your file shares local? Just want to enable remote access without moving data to the Cloud? CentreStack can do that. This use case is suitable for businesses with pretty good bandwidth and wants to quickly turn on secure remote access, mobile file sharing, and web-based collaboration features.

Direct Access

Secure, remote access to on-premise file shares. Avoid replicating data to the cloud!

User Friendly

Easy, familiar user interface such as driving mapping and file locking to reduce ramp up time.


Group policies include ransomware protection, endpoint encryption, AV integration and more

Permission Controls

Maintain existing Windows security, control and compliance with full support for NTFS permissions and Active Directory

Auditing History

Add security and compliance features like auditing & reporting with file change logs. The version control feature adds protection too.

Endpoint Backup

Endpoint devices connected to the CentreStack server will have the endpoint backup features to protect the files and folders further.


File Shares Migration to Cloud Storage Services

Migrate existing file shares and permissions to cloud storage. Retire your file server or keep it running as a local gateway with caching for offline access.

Central File Repository

Keep data in one place for both file server shares and cloud file sharing instead of allowing data to scatter.

NTFS Permissions

Centrally manage granular NTFS permissions and AD users with auditing and reporting for all activities.

Simplified Access

Simplify file server access from mapped drives on Windows and macOS, mobile apps on iOS, Android and web browsers.

Distributed Teams

The solution combines file server network shares from multiple branch offices into one consistent global namespace.

Business Continuity

Data saved to file shares replicates to the cloud and vice versa for business continuity with hybrid deployments.

File Locking

In addition to manual file locking, automatic file locking, combined with version controls, protects distributed access and file collaboration.

Are you ready to try something new?

If the SharePoint limitations are holding you back from migrating file servers to Cloud, there is a better way!

File Server Migration & Remote Access Architecture

Step 1: Auto-Synchronization

After installing CentreStack, the Cloud Server Agent is installed on the local file server. This will automatically synchronize file shares, AD users, and NTFS folder permissions to the CentreStack installation in the cloud.

Step 2: Mapped Drive Access

After login, users automatically get a mapped drive that contains all the shares they have access to, just as if they were on-premise.

Step 3: Client File Server Sync

CentreStack maintains synchronization with the client file server until it has been retired. It also remains the primary source for permissions and acts as an optional proxy to the local domain controller.

Step 4: Quick Access

When a user attempts to open a file on the endpoint, it is downloaded from the backend storage configured for CentreStack and cached locally for fast future access.
