Turn Any Tape Library Into
an S3 Glacier-compatible Archive.

S3 Glacier-compatible interface. Tape library durability. No cloud lock-in.
XtreemStore turns existing tape libraries into an S3 Glacier-compatible tape archive, so applications keep using familiar S3/Glacier-compatible workflows while data stays under your control.

Enterprise-Grade Features

Built for S3 Glacier-compatible tape archiving at enterprise scale.

Modern Interfaces

S3 Glacier-compatible archive interface with optional HSM file system access (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

Use tape economics without cloud lock-in by keeping your archive on infrastructure you control.

S3 Glacier-compatible Interface.
Any Tape Library.

XtreemStore provides an S3 Glacier-compatible archive interface over tape libraries. A configurable disk cache tunes ingest and recall performance while preserving long-term tape economics.

  • 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-aware archiving for efficient placement, recall, and storage optimization.

XtreemStore Data Flow

XtreemStore Architecture Diagram

Applications write via an S3/Glacier-compatible API. Data lands on a tunable disk cache for performance, then is grouped and written to tape libraries for long-term, air-gapped archive 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.

Customer Spotlight:
Technical University of Dresden

"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..."

— 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.
