Our verdict on Cubbit DS3
Cubbit DS3 is a geo-distributed object storage platform for organizations that need managed cloud storage, self-hosted infrastructure, or a combination of both. DS3 Cloud provides S3-compatible managed storage with multi-region storage included, while DS3 Composer supports managed or self-hosted deployments on public-cloud, bare-metal, or customer-owned infrastructure. Its positioning fits backup, disaster recovery, AI data lakes, and large-scale enterprise storage workloads across small, mid-market, and enterprise environments.
Pricing is structured around both access and deployment choice. DS3 Composer has a free tier, and its personal-use plan is published at €4.99 per TB per month for 3–10 TB. DS3 Cloud offers a 30-day trial with a 1 TB test environment and no credit card required; its paid pricing is quote-based. Larger DS3 Composer business volumes also use custom configurations and discounted pricing for PB-scale deployments. DS3 Cloud includes no egress, deletion, bucket replication, or API fees, which makes its cost model particularly relevant for backup and data movement workloads.
The platform’s strongest fit is for teams that need S3 compatibility without limiting deployment to one cloud model. Multipart uploads, versioning, Object Lock with legal hold and retention modes, AES-256 encryption, Reed-Solomon redundancy, lifecycle expiration rules, and cross-region replication cover core durability and governance needs. AWS CLI, AWS SDKs, rclone, Veeam, Commvault, Synology tools, Cyberduck, and CloudBerry Backup support broader ecosystem compatibility. Choose DS3 when geographic distribution and deployment control matter; a narrower cloud-only service may suit teams that prefer simpler administration and fully standardized pricing.
