ExaGrid attaches behind Rubrik as an on-premise archive target — not a rip-and-replace. Rubrik stays in place. ExaGrid extends it with additional deduplication, faster restores, ransomware resilience, and dramatically lower TCO versus cloud archive.
Rubrik compressed and deduplicated data is sent to ExaGrid via Rubrik Instant Archive for further deduplication. ExaGrid replicates to a second site for DR with up to 50:1 WAN efficiency.

Data lands in a disk-cache for fast ingest. Restores at full disk speed — minutes, not hours from cloud. No egress fees.
Adaptive dedup runs in background, achieving 3:1 to 10:1 additional reduction on top of Rubrik's own compression.
Deduplicated data replicates to a second ExaGrid with 50:1 WAN efficiency. Supports up to 16 sites, hub-and-spoke or multi-hop.
ExaGrid improves Rubrik environments across four critical categories.
Fast ingest keeps backup windows short. Restores at disk speed from on-premise. Fast VM boots for instant recovery. No cloud egress bottleneck.
Non-network-facing Repository Tier for ransomware recovery. DR replication. AI-powered threat detection. Immutable data objects. 3rd-party validated.
Scale-out — pay as you grow. No forklift upgrades, no planned obsolescence. 5-year price protection. Low rack space (2U). Reduced storage through dedup.
Assigned Level 2 senior engineer — no junior techs. In-theater worldwide support. Health reporting. No hidden costs. +81 NPS. 99% on maintenance.
Each appliance is a full server. Adding appliances increases both capacity and performance linearly — the backup window stays fixed as data grows. Mix and match any age and size. 7-year useful life (HDD) / 5 years (SSD).
New SSD appliances deliver fastest backups/restores with lower power. 4 models from 90TB to 540TB usable. Landing Zone is 20% of repository. Can mix SSD primary with HDD at DR for cost optimization.
| Model | Usable | Weekly Full | TB/hr |

| EX90-SSD | 108 TB | 90 TB | 115.2 |
| EX135-SSD | 161 TB | 135 TB | 115.2 |
| EX270-SSD | 323 TB | 270 TB | 115.2 |
| EX540-SSD | 645 TB | 540 TB | 115.2 |
Side-by-side comparison of storing Rubrik archive data in the cloud versus on-premise ExaGrid.
| Capability | Rubrik + Cloud Archive | Rubrik + ExaGrid On-Premise |
|---|---|---|
| Cost Model | Recurring monthly per-TB charges that compound | One-time HW purchase + predictable maintenance |
| Egress Fees | ✗ Charged per GB on restore | ✓ Zero — all data on-premise |
| Restore Speed | ⚠ Hours to days | ✓ Minutes — disk-speed Landing Zone |
| Additional Dedup | ✗ None — cloud stores as-is | ✓ 3:1 to 10:1 on top of Rubrik |
| Ransomware Air Gap | ⚠ Cloud creds can be compromised | ✓ Non-network-facing tier + immutable objects |
| AI Threat Detection | ✗ Not available | ✓ Auto Detect & Guard with AI neural network |
| DR Replication | Cloud-to-cloud vendor lock-in | ✓ Site-to-site 50:1 WAN, up to 16 sites |
| Price Predictability | ✗ Subject to cloud pricing changes + growth | ✓ 5-year fixed, M&S capped at 3%/yr |
| Sizing Effort | N/A (pay as you store) | ✓ 20-min sizing from Rubrik console |
Non-network-facing Repository Tier acts as a tiered air gap — a second layer of ransomware protection behind Rubrik.
Even if ransomware sends delete commands, the Repository Tier is not impacted. Non-network-facing tier, delayed delete policy, immutable data objects — data is always ready to restore.
Built-in AI neural network monitors delete patterns. On abnormal detection: alerts fire, delayed delete extends indefinitely, all objects stay immutable. IT team investigates and clears when ready.
100% focused on backup storage for over 18 years. The largest independent vendor with industry-highest satisfaction.
