Archiving without the lock-in tax.

Most archiving vendors take custody of your data - hosting it on infrastructure you don't control, charging you to access your own information. We took the opposite approach.

Squirrel and Chipmunk write directly into your Azure Blob Storage account - restorable on demand, always sitting in your tenant, under your governance, not ours. Squirrel also encrypts and compresses archived content before upload.

Your tenant, your data

Archives land in your Azure Storage account. We never hold a copy. Compliance, sovereignty and exit strategy by design.

Encrypted and compressed

Squirrel encrypts archived content at rest and compresses it before upload to shrink your storage footprint. Both Squirrel and Chipmunk restore on demand through self-service tooling.

Cut storage spend

Push cold SharePoint content into Hot, Cool or Archive tier blob storage and slash per-GB costs by up to 90%.

Compliance-friendly

Retention rules, audit trails and immutability that fit Microsoft Purview, GDPR and industry-specific requirements.

• 333,410,408% Reduction in SharePoint storage spend, typical
• 392,247,539% Your archive lives in your own Azure subscription

Specialist software. Trusted by enterprise IT teams.

Six things every Microsoft 365 customer can count on with SmiKar - backed by Microsoft Partner status, Azure Marketplace verification and customer-tenant data sovereignty.

Registered Microsoft Partner

Listed in the Azure Marketplace as a registered Microsoft Partner. Specialist independent software vendor (ISV) for the Microsoft 365 ecosystem.

Azure Marketplace verified

Chipmunk deploys directly from the Azure Marketplace into your own subscription - procurement via your existing Microsoft enterprise agreement, no separate ISV contract required.

Customer data never leaves your tenant

Squirrel and Chipmunk write archives directly into your own Azure Blob Storage account. SmiKar never holds a copy of customer data, ever.

Encrypted, auditable, compliant

AES encryption at rest. Compression before upload. Per-job audit trail. Aligned with Microsoft Purview, GDPR and industry-specific retention requirements out of the box.

Engineering-led support

Direct access to the product engineers when you need them. Replies within one business day, often the same day. Built for IT teams that don't have time for support-ticket queues.

Purpose-built for Microsoft 365

Years of focused work on the SharePoint and Microsoft 365 archiving problem - not a feature inside a broad platform trying to do everything. Specialists, doing what specialists do.

Field notes for IT leaders.

Inactive Mailbox vs Shared Mailbox vs Archive Mailbox in Microsoft 365

Three Exchange Online mailbox types admins constantly confuse - what each one is for, the licence rules, and which to use when an employee leaves.

Microsoft Copilot and Archived SharePoint Content: The Visibility Gap

Microsoft Copilot cannot see archived SharePoint content in either Microsoft 365 Archive or standard third-party archives. Here's why - and how to close the gap.
