The responsibility gap

Who backs up your Microsoft 365 data? Not Microsoft.

Microsoft runs the service: the datacentres, the uptime, the platform. Protecting the content inside it is your side of the shared responsibility model. Their own customer agreement says so:

Microsoft answers for

  • Keeping the service online
  • Datacentre and platform failures
  • The infrastructure your tenant sits on

You answer for

  • Everything inside your mailboxes and sites
  • Deletions: accidental, departing staff, malicious
  • Ransomware that reaches synced files
  • Getting it all back, when it happens
“We recommend that you regularly backup Your Content and Data that you store on the Services or store using Third-Party Apps and Services.”

Not a backup

The recycle bin

Permanently deleted mail is kept 14 days by default, 30 at most. Work or school files in the recycle bin are gone after 93 days. Then it’s unrecoverable.

Not a backup

Retention policies

A retention policy decides when data may be deleted. It governs expiry; it cannot rebuild a mailbox, and a mis-set policy is itself a way to lose everything at once.

Not a backup

Litigation hold

A legal instrument that freezes content for evidence. It preserves; it doesn’t restore. You can’t rebuild Monday morning’s inbox from a hold.

Not a backup

Geo-redundancy

Protects Microsoft’s platform from a regional disaster. It does nothing when the deletion comes from inside your own tenant, which is the far more common case.

How it actually happens
  • Deleted by mistake
  • Emptied by a departing employee
  • Encrypted by ransomware
  • Wiped by a compromised admin
  • Noticed six months too late
Setup

Three steps. Then it’s just handled.

No appliance, no agent on every laptop, no migration. You grant access, choose what matters, and Parity Backup keeps a complete, encrypted copy in Finland (EU) from then on.

01

Consent

Connect your tenant with a standard application consent. You see exactly which permissions are requested, you grant them as your own admin, and you can revoke them at any time.

02

Choose

Pick what to protect: whole mailboxes and their archives, files, sites. You pay only for the seats you actually protect, and you can change the selection whenever you like.

Mailboxes, primary & shared
In-Place Archive mailboxes
Files & folders
Team sites & document libraries
03

Done

Backups run automatically from then on. Every snapshot is encrypted, deduplicated and immutable. Restore to the original location, to another location, or download an export.

point-in-time snapshots

No standing access for anyone else. The copy lives in Finland (EU), encrypted at rest and in transit.

Why Parity

Built by the people who’d get the 3 a.m. call.

Parity Backup was written by a managed service provider to protect its own clients’ tenants first, including the archive mailboxes other tools quietly skip.

01 · Service

Managed, end to end

Nothing to install, nothing to host. Connect your tenant with admin consent, choose what to protect, and the first snapshot runs. We operate the infrastructure.

02 · Archives

In-Place Archives included

Archive mailboxes are backed up and restorable, not skipped. Many tools are built on an API surface that cannot reach archives at all, and won’t tell you that.

03 · Snapshots

Immutable history

Every backup is a point-in-time snapshot in content-addressed, deduplicated storage, encrypted at rest and in transit. Unchanged data is stored once, so deep history is cheap.

04 · Terms

Monthly. Cancel anytime.

Per-seat billing with no annual lock-in. Pay only for the seats you protect; change the count whenever you like.

05 · Custody

No standing third-party access

Your backups don’t live on a backup vendor’s multi-tenant cloud. The copy is stored in the EU on Hetzner infrastructure in Finland, and no third party holds standing access to it.

06 · Honesty

Plain scope, in writing

What’s covered is covered properly. What isn’t, and what no vendor can do, is stated plainly, right here on the site. See the coverage list below.

Security

Security, stated precisely.

Backup buyers check the security behind a vendor. Here is exactly what stands behind Parity Backup: where your data lives, how it is held, and who can reach it.

01 · Where it lives

Certified EU facilities

Backups are stored and processed on Hetzner infrastructure in Finland. Hetzner’s datacentre parks, including Helsinki, are certified to ISO/IEC 27001:2022: Hetzner certification. Your data’s landlord holds the certificates.

Finland is where we put it by default, and part of why the price is what it is: choosing Hetzner is how a seat costs $2 instead of $6. If your own policy or your regulator needs it somewhere else, we can store your backups in Azure, Wasabi or another provider you name, at additional cost. Ask us for a quote.

02 · How it’s held

Encrypted and immutable

Every snapshot is encrypted at rest and in transit, content-addressed and deduplicated. Access to your tenant comes from your own admin consent, revocable by you at any time. No third party holds standing access to your backups.

03 · Who can reach it

No standing access

Nobody at Parity Backup keeps a key to your data. Access to your tenant is the admin consent you grant and revoke, and there is no back door: our support team can only reach your account through a secure access code, used for support and nothing else. The company holds Cyber Essentials, the UK government-backed security certification.

What Parity protects, and what it doesn’t.
