Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cloudian

  • You operate the hardware, so capacity planning, firmware, node failures and a refresh cycle every five years return as costs that a public cloud bill hides.
  • Per-terabyte licensing plus servers means high upfront cost, and the crossover point against public cloud only arrives at meaningful scale, typically hundreds of terabytes and up.
  • S3 compatibility is high but not identical to Amazon, so occasional applications depending on newer or less common S3 features need testing rather than assumption.
  • Small deployments need a minimum node count for erasure coding to be meaningful, which sets a practical floor on entry cost regardless of how little data you have.
  • Performance is object storage performance, so it is not a substitute for block or high-throughput file storage and buyers occasionally deploy it for the wrong workload.

Rubrik Cloud Data Management

  • Requires substantial upfront investment with enterprise pricing models
  • Complex implementation and integration with existing infrastructure
  • Complex configuration with many options for policies, bulk operations limits, and error handling
  • Limited built-in analytics compared to some competitors

Answered from the vendors’ own pages

Cloudian: Does object lock really stop ransomware deleting backups?

Within the retention period, yes, provided the lock is set in compliance mode. That is precisely why it is the common answer to backup-targeting ransomware.

Rubrik Cloud Data Management: What ransomware protection does Rubrik offer?

Rubrik offers immutable backups that cannot be altered or deleted, providing zero trust data security. Enterprise customers receive a $10M ransomware recovery warranty for both on-premises and Rubrik managed cloud environments.

Cloudian: Are there egress charges?

No. That is the central cost argument against public cloud object storage, and it only becomes visible when you have to restore at volume.

Rubrik Cloud Data Management: How quickly can Rubrik recover from data loss?

Rubrik enables near-instantaneous recovery of virtual machines and databases, minimizing downtime. Global Real-Time Search provides Google-like search across all backups to quickly locate and restore specific files.

Source
Cloudian: Can we use our own servers?

Yes, HyperStore is software-defined and runs on qualified commodity hardware, or you can buy Cloudian appliances if you would rather not certify your own.

Rubrik Cloud Data Management: What cloud platforms does Rubrik support?

Rubrik supports cloud mobility across AWS, Azure, and Google Cloud, enabling data migration and replication to various cloud platforms.

Source
Rubrik Cloud Data Management: Does Rubrik reduce storage requirements?

Yes, Rubrik uses global deduplication to eliminate redundant data across all backups, significantly reducing storage requirements and optimizing storage efficiency.
