Microsoft 365 backup

A backup product built into the platform, not a third-party line item bolted onto your stack. Nexus walks your Microsoft 365 tenant through the Graph API — Exchange Online mailboxes, OneDrive drive trees, and SharePoint document libraries — and writes them to an S3-compatible bucket you own (Wasabi, AWS S3, or Cloudflare R2), not ours. Every object is hashed and verify-checked, retention prunes on your schedule, and restore is per-item, not all-or-nothing.

What it does

Exchange Online, OneDrive, and SharePoint backup via the Microsoft Graph API
Writes to your own S3-compatible bucket — Wasabi, AWS S3, or Cloudflare R2 — with keys encrypted at rest
SHA-256 verification on every object and a verify-by-rehash pass, so a backup is proven, not assumed
Retention pruning and run history on a per-tenant schedule
Per-item restore and signed download — recover one mailbox or file, not the whole tenant
