Back up and restore yourExchange mailboxesExchange mailboxesinto storage you own.
BYOVault is the bring-your-own-storage standard for Microsoft 365 backup.
One console protects SharePoint, OneDrive, and Exchange, writing every encrypted backup straight into your Azure Blob or AWS S3 account — never ours.
Microsoft won't restore it for you. That's your job.
The shared-responsibility model puts M365 data recovery squarely on you. Retention windows expire, deletions replicate, and attackers go for the backups first. Owning a copy in storage only you control is the last line of defense.
AES-256-GCM
Every file encrypted before it ever leaves BYOVault's pipeline.
Your storage
Written straight to an Azure Blob or S3 account you own.
Full version history
Every backed-up version, restorable, not just the latest.
Per-drive retry
One stalled drive never restarts the whole backup.
So “backed up” has to actually mean something.
Six things BYOVault actually does today — not a roadmap.
Backups are written directly into the Azure Blob or Amazon S3 account you already pay for. No vendor-held copies, no per-GB markup, no data leaving the cloud account you chose.
AES-256-GCM, with a key derived per tenant. Anyone reaching your storage account directly sees only ciphertext — never a readable file.
Search across every backed-up version and restore a single mail item, a file version, or a whole SharePoint site — back in place or downloaded directly. Every restore is checksum-verified.
Manage every client tenant from one dashboard, each with its own storage destination, schedule, and workload selection — one pane of glass across the whole book of business.
When a file ages past your retention window, it's moved into a genuinely separate, provider-locked vault — real storage-layer protection, enforced by AWS or Azure themselves, not just a database setting. Preserve a file, folder, or entire drive to keep it out of that lifecycle entirely.
A dedicated portal lets end users browse their own Exchange mailbox and OneDrive, request a restore, and track it — without filing an IT ticket. A designated approver signs off before anything runs, so nothing executes unreviewed.
One engine for every workload. Storage you already own.
No agents to manage for M365, no appliances. API-native protection across SharePoint, OneDrive, and Exchange, written to the bucket of your choice.
Exchange
Mailbox messages, per folder, with delta sync.
SharePoint
Site libraries and document drives, file-level, with version history.
OneDrive
Personal drives, file-level, with full version history.
File servers
On-prem shares backed up via a lightweight local agent.
Move providers without re-architecting.
Switch clouds on your terms — your backups already live in a standard blob/object store, not a proprietary vendor format.
Four steps, no new hardware.
From an empty account to a running, scheduled backup — no agents to install for M365, no appliance to rack.
Connect your M365 tenant
A standard Microsoft Entra OAuth consent grants access. No passwords stored.
Attach your storage
Point BYOVault at your Azure Blob container or S3 bucket. Credentials are encrypted, never stored in plaintext.
Set workloads and schedule
Pick SharePoint, OneDrive, Exchange, or all three, and set a daily, weekly, or monthly schedule per workload.
Restore anytime
Search every backed-up version and restore a file or email on demand, verified by checksum.
