Object cloud backup 2026: Wasabi vs Backblaze vs S3 vs OVH.
Neutral comparison of the 4 leading S3-compatible solutions for SME backup. Pricing, egress, immutability, sovereignty.
Wasabi Hot Cloud Storage
SMEs 1-200 TB, Veeam/Acronis backup, FinOps-first
- ✓No egress fees (free downloads)
- ✓No API call fees (unlimited PUT/GET)
- ✓Ultra-predictable pricing (single invoice line)
- ✓Native immutable Object Lock (anti-ransomware compliance)
- ✓EU regions: Paris, Amsterdam, Frankfurt, London
- ✓100% Amazon S3-compatible API
- ✓11 nines durability
- −Minimum 1 TB billed even if only 100 GB used
- −Minimum 90-day retention (deletion before then is billed)
- −Fewer native integrations than AWS S3
- −Average restore performance (fine for backup, not for analytics)
Veeam + Acronis backup, long-term SME archives, maximum FinOps
Backblaze B2 Cloud Storage
SMEs 1-100 TB, tech teams, dev tooling integration
- ✓Competitive pricing (among the cheapest)
- ✓10 GB egress/day free (generous)
- ✓S3-compatible API + native B2
- ✓Native Object Lock + Cloud Replication
- ✓US + EU datacenters (Amsterdam)
- ✓Cloudflare/Fastly CDN partnership (free egress via them)
- ✓Free tier 10 GB (POC + dev)
- −No France region (Amsterdam is the closest EU)
- −Admin tooling less rich than AWS/OVH
- −No SecNumCloud / FR sovereignty certification
Tech-savvy backup, B2 integration in dev pipelines, FinOps + egress flexibility
AWS S3 Glacier Instant Retrieval
SMEs already on AWS, integrated ecosystem, compliance archiving
- ✓Glacier Instant Retrieval archive: ms restore (vs hours for Glacier Deep)
- ✓Native integration with AWS services (Lambda, CloudWatch, Backup)
- ✓Automatic lifecycle policies (S3 Standard → Glacier auto)
- ✓Object Lock + Vault Lock compliance (SEC 17a-4, FINRA)
- ✓Regions Paris (eu-west-3) + Frankfurt + Stockholm
- ✓Immense AWS ecosystem documentation + tooling
- −Very expensive egress ($0.09/GB = ~$90/TB downloaded)
- −Opaque pricing: unpredictable invoices when traffic varies
- −Subject to the US Cloud Act
- −Min storage duration 90 days (early delete fee)
- −Min object size 128 KB (otherwise billed as 128 KB)
Long-term compliance archive, 100% AWS organizations, rarely restored datasets
OVHcloud Cold Archive
French SMEs, OIVs, sensitive data with sovereignty needs
- ✓Unbeatable cold archive pricing (~€1.30/TB/month)
- ✓French sovereignty (no Cloud Act)
- ✓Datacenters in Roubaix, Strasbourg, Gravelines, Beauharnois
- ✓S3-compatible API
- ✓No standard API fees
- ✓Good integration with OVH Public Cloud (Object Storage + Cold Archive lifecycle)
- ✓SecNumCloud available for dedicated offers
- −Cold Archive: restore takes 4-24h (not instant)
- −Less UX tooling than AWS/Wasabi
- −API docs sometimes fragmented
- −Egress €0.01/GB (free on Wasabi)
Price-driven long-term compliance archive, FR sovereignty organizations, rarely restored datasets (>1/year)
