Both Acronis Cyber Protect Cloud and North Brook Vault offer cloud-to-cloud backup for Microsoft 365, but their underlying architectures target completely different engineering philosophies. Acronis bundles endpoint security, anti-malware, and backup into a unified agent ecosystem, while North Brook Vault focuses exclusively on high-throughput M365 workload protection with bring-your-own immutable storage.
Storage Control & Immutability
Acronis defaults to Acronis Cloud Storage, a proprietary, managed cloud repo. While convenient, it locks your data into the Acronis ecosystem and limits direct S3 Object Lock configuration.
North Brook Vault allows you to attach any S3-compliant target (AWS S3, MinIO, Wasabi, Cloudflare R2). You maintain full ownership of the bucket policy, KMS keys, and WORM retention, guaranteeing that even if our software vanishes, your raw backup data remains completely accessible and tamper-proof.
Handling Microsoft Graph Limits
Large tenants regularly run into Microsoft Graph API 429 throttling errors. Acronis handles throttling via standard retry mechanisms. North Brook Vault implements continuous multi-tenant Graph token pooling and automated delta-link queueing, enabling seamless backup runs across tens of thousands of mailboxes without getting throttled by Azure AD limits.
Which Should You Choose?
Choose Acronis if you are an MSP seeking an all-in-one suite covering endpoint anti-virus, patch management, and basic M365 backup. Choose North Brook Vault if you require dedicated M365 compliance, custom S3 immutability, granular Teams chat restoration, and lower long-term storage costs.
