Build a centralized data storage system right within the enterprise. File sharing, manage access and protect data with ZFS technology — no pay for capacity, Don't worry about data getting out of control.
✓ No GB fees · ✓ Data stored at the enterprise · ✓ ZFS prevents data loss

The entire solution is built entirely on the company's infrastructure (On-premise) and can operate with an independent storage system (Air-gapped). This is the optimal model to ensure data sovereignty, privacy and eliminate dependence on third-party Cloud providers thanks to 100% autonomy from hardware to software.
Public cloud storage is designed for ease of use — not for control over corporate data. As scale grows, these limits become more and more apparent.
Google Workspace Business Standard: ~400,000 VND/user/month. 50 employees = 20 million/month = 240 million/year — and increases when adding more people. With a private File Server, adding 100 users doesn't cost you any more.
Customer contracts, payroll, business plans — all stored on Google/Microsoft servers in Singapore or the US. There is no control over who can access it according to legal requirements in those countries.
It is not known which files the employee has downloaded and shared with anyone outside. When a data breach occurs, there are no complete logs to investigate. Internal File Server allows auditing of each access action down to the file level.
From file sharing, permission management, automatic snapshots to off-site replication — everything is built-in, no additional software needed.
New generation file system with checksum of each data block — automatically detects and corrects bit rot errors, protecting data at the highest level.
Supports all operating systems and devices — Windows, Mac, Linux, iOS, Android all connect without needing to install special software.
Take snapshots automatically according to schedule — hour, day, week. Restore files or entire folders to any point in history with just a few clicks.
Active Directory/LDAP integration — single sign-on, decentralization by department, group and individual with detailed ACLs for each folder.
Replicate data to a backup site or cloud backup according to schedule. Ensure data is safe even if the main server is completely broken.
Provides S3-compatible API on-premise — S3-integrated applications run with internal storage without code changes.
All the power of an enterprise NAS/SAN system — no need to purchase separate solutions.
Same storage needs — completely different costs and levels of control after 3 years.

Open source File Server is freely licensed for any commercial use. You only pay once for hardware and deployment services — no subscriptions, no annual renewals.
Adding 100 employees does not cost additional licenses. Adding 10 TB of storage costs only the physical drive — no vendor fees.
RAID typically fails to detect bit rot (silent data errors). ZFS checkssum every block and corrects errors automatically — this is the technology that expensive enterprise storage systems are using.
When an employee leaves, you remove permissions immediately — there are no "syncing" files on their laptop. Every access has a full log.
Connect to Active Directory, ERP, accounting software via SMB/NFS/iSCSI — no need to pay additional integration fees for each application.
Comparison for 50 employees / year — license/subscription cost
* NAS hardware and deployment costs are calculated separately, typically paid back in 12–24 months.
"We have 80 employees using Google Drive Business for ~25 million/month. After switching to File Server, all data is internal, subscription costs go to 0 and internal file access speed is much faster."
"My company has very sensitive design data - it cannot be stored in a foreign cloud. The internal File Server completely solves the compliance issue, and simultaneously stores large 3D files unlimitedly without worrying about running out of quota."
"Automatic hourly ZFS snapshots saved us twice — once because an employee mistakenly deleted an important folder, once because of ransomware. Restored in 10 minutes, no data lost. Before using Google Drive, this feature was not available."
Standardized process across many projects — no disruption to employees' work during the migration process.
Evaluate the number of users, current capacity, and required protocol (SMB/NFS/iSCSI). Consulting on budget-friendly NAS hardware.
Install the file server operating system, create a ZFS pool, configure shares, ACLs, Active Directory integration and backup policies.
Transfer data from old Google Drive/OneDrive/NAS to new File Server. Migration takes place in parallel, without interrupting work.
Instruct employees to connect to Network Drive, set up automatic backups, and hand over operating documents to internal IT.
Once deployed, you own the system completely — no subscriptions, no annual licenses, no vendor dependence.
Suitable for businesses with ≤30 employees, 1 single NAS, basic SMB/NFS connection and automatic snapshots.
Suitable for 30–150 employees, Active Directory integration, off-site replication and Cloud Sync backup.
150+ employees, HA cluster, geo-replication, large-scale S3 object storage, and long-term managed services.
✦ Committed to transparency: No hidden license fees. No monthly subscription. Once deployed, File Server is your business's asset — completely independent of NAD.
