Your On-Premise Glacier.
XtreemStore Without Limits.
Enterprise-Grade Features
Engineered for scalability, security, and interoperability.
Modern Interfaces
S3 Glacier interface, optional HSM file system (Windows/Linux), and a Data REST API for custom integrations.
Open Standards
Uses LTFS and TAR to ensure your data is always accessible and future-proof. No vendor lock-in.
Air-Gap Security
Physical isolation protects against ransomware. Create up to four tape copies for redundancy.
Simplified Management
Intuitive WebGUI and CLI simplify tape management, even for those not familiar with tape.
Scalability
Proven to scale to billions of objects and hundreds of petabytes to meet your storage needs.
Unbeatable TCO
Benefit from the cost efficiency of tape and maximize your Total Cost of Ownership.
Simple Architecture.
Unlimited Scale.
XtreemStore combines proven tape reliability with cloud-like object storage. Configurable disk cache tunes performance for your workload. Scale vertically or horizontally.
- Policy-based disk cache (internal HDD or SAN) for tunable read/write performance.
- Scales to billions of objects and hundreds of petabytes.
- Manage one or more tape libraries and create up to four tape copies.
- Intuitive WebGUI and CLI for smooth user experience.
- Asynchronous multi-site replication to a second XtreemStore.
- Metadata-driven archiving for efficient storage optimization.
XtreemStore Data Flow

Applications write via a standard S3/Glacier API. Data lands on a tunable disk cache for performance and is then grouped and written to any tape library for long-term, air-gapped storage.
Built for Real Workloads
Purpose-built for storage admins and enterprises managing petabyte-scale data
PACS & Medical Data
Geo-redundant archiving of DICOM and medical records with compliance-friendly tape transport.
Backup & Archive
Veeam V12, Commvault, and native cloud tools write directly via S3/Glacier API.
M&E Content
Manage TBs of video and media with metadata-driven grouping and fast recall.
R&D Data
Archive research datasets with multi-site replication for disaster recovery.
HSM & Tiering
Seamless hierarchical storage management with NFS/SMB frontend.
Compliance
Long-term retention with air-gap security and audit trails.

"The Mediaflux data management platform and the XtreemStore software form the ideal combination for customers who need to manage and provide very large amounts of data..."
โ Herbert Grau, CEO of GRAU DATA
The Challenge
Facing massive volumes of data across multiple storage platforms, the university had limited visibility and inefficient archiving processes, making it difficult to access cold or archived files.
The Solution
TU Dresden implemented XtreemStore to optimize data archiving on LTO magnetic tape, using the S3 Glacier interface to seamlessly move cold data to cost-effective storage.
The Results
The university benefits from a powerful, scalable system that dramatically reduces storage costs while maintaining full visibility and access to all archived files.
Stop Overpaying for Storage.
Your egress fees and storage costs are only going up. Our engineers build custom TCO models for enterprises managing petabyte-scale data. Schedule a 30-minute analysis and see your 5-year savings.
