What is DS3?

DS3 is a fully-managed, S3-compatible object store. Unlike traditional cloud storage, DS3 doesn't store data in a few centralised data centres. Instead, files uploaded to DS3 are protected by several layers of security:

Cubbit technology

#1 Encryption

First, data is encrypted with AES-256, a military-grade encryption algorithm.

#2 Splitting

The encrypted data is fragmented into N chunks, each indistinguishable from one another.

#3 Redundancy

These N chunks are replicated into K shards via Reed-Solomon error-correcting codes.

#4 Geo-distribution

Finally, each shard is securely stored across multiple geographical locations within a single country.

This addresses nations’ specific data sovereignty concerns, helping businesses check all the compliance boxes (e.g. ISO and GDPR), while providing data control and hyper-resiliency against ransomware and localised disasters.

The next evolution of cloud storage

Redundancy at no extra cost

Get a simple, CapEx-friendly price, with no extra cost for redundancy, egress fees or surprises on your budget.

Ransomware resistant

Make your data ransomware-proof thanks to multi-site object lock, versioning, IAM policy, encryption, and geo-distribution.


Geofence the area where your data is stored, in full compliance with your nation’s specific data regulation (e.g. GDPR, ISO, CCPA).


Thanks to geo-distributed technology and by choosing green data-centers, we extend the storage hardware lifespan and minimise your carbon footprint.

DS3 is compatible with Veeam, Nakivo, and the whole S3 ecosystem

1 bucket, multiple locations

Unlike centralised cloud storage, DS3 lets you save one bucket in multiple locations at the same time. This gives you several advantages:

True hyper-resiliency

In case one or multiple locations are unavailable, you can still access and back up your data, unlocking unmatched data durability and availability.

Reduced RTO

If one or multiple locations are unavailable, you can still restore your data without complex manual bucket restores to the original location (as you'd do on centralised cloud storage).

Multi-site object lock

DS3 lets you object lock a bucket in multiple locations simultaneously, optimising your workload while making your files truly ransomware-resistant.

We used to do backups for disaster recovery with other US providers. Now we moved a part of it to Cubbit. The advantage is having ransomware protection, geographic proximity for performance, and fulfilling GDPR-related issues.
