SharePoint Archiving Buyer's Guide & Checklist

The SharePoint Archiving Buyer's Guide & Checklist

A vendor-neutral guide to evaluating SharePoint archiving, for M365 and IT leaders.

Why This Matters Now

SharePoint estates only grow. Document libraries accumulate years of files no one has opened, and nothing in Microsoft 365 nudges anyone to clean them up. That quiet growth has three consequences that have become urgent:

• Storage pressure and cost. You are paying to keep content that delivers no value, and additional SharePoint storage carries a premium.
• Copilot and search quality. Microsoft 365 Copilot grounds its answers on what is in your tenant. Stale, inactive, and duplicate documents pull search and Copilot toward noise, degrading results for everyone.
• Governance and risk. The more content you retain without a policy, the larger your compliance and discovery surface.

Archiving fixes this, provided the tool you choose does not create new problems in the process. The wrong archiving solution locks up your data, frustrates end users into raising tickets, or quietly breaks your compliance posture. Use the questions below to pressure-test any vendor, including us.

How to use this: score each vendor honestly against every question. Any "no" or vague answer in sections 1, 2, or 3 is a serious flag. Those are the areas that are expensive or impossible to fix after you have committed.

1. Restore and the End-User Experience

The single biggest reason archiving projects fail is that restore is painful, so users hoard and IT gets blamed.

• When a user needs an archived file back, can they restore it themselves, or does it require an admin, a ticket, or a support call?
• Is restore a single click, or a multi-step process?
• Is there any charge to restore a file, such as data retrieval or egress fees, or is restore included?
• How quickly does a restored file come back: is it available immediately, or is there a delay while it rehydrates from a cold storage tier?
• Are version history, metadata, and permissions all preserved on restore, or does the file come back stripped?
• What does a user see in SharePoint where the file used to be: a working placeholder, a dead link, or nothing at all?
• Can external guests with legitimate access to a library restore content too, or does archiving break their workflow?

What good looks like: the file appears to still be there; any user with permission clicks once and the original is back immediately and fully intact, with no surprise retrieval charge.

Red flag: restore is an IT task, archived files simply vanish from the library, or bringing a file back triggers retrieval fees or an hours-long rehydration wait. This failure mode is common enough that restoring archived SharePoint content is one of the most-searched archiving problems.

2. Data Ownership and Lock-In

This is the question that is impossible to walk back later. Where your data lives determines who has power in the relationship.

• Where does the archived data physically reside: in the vendor's cloud, or in your own Azure storage?
• If you stop paying, can you ever be locked out of the storage account holding your data?
• Do you retain full control and access to that storage at all times, with no vendor acting as gatekeeper?
• Is your data ever held inside the vendor's own tenant?

What good looks like: the archive is written into an Azure storage account you own and control, in your own subscription. The vendor operates the service but never holds your data hostage.

Red flag: "our platform stores it for you." That is leverage against you at renewal time.

3. Governance, Compliance and Audit

Archiving moves regulated content. If it moves outside your compliance boundary, you have created a problem, not solved one.

• Is there a complete audit trail of what was archived, when, and by whom?
• Does the solution work alongside Microsoft Purview and your existing retention policies, rather than fighting them?
• Can you apply retention and immutable (WORM) tiers to archived content?
• Are existing library permissions respected on both the archived item and the restored file?

What good looks like: archiving is fully logged, Purview-compatible, and supports immutable retention.

Red flag: no audit trail, or content that leaves your compliance scope the moment it is archived.

4. Copilot and Search Impact

Archiving is not just cleanup. Done right, it directly improves the quality of Copilot's answers.

• Does archiving actually remove stale content from what Copilot and search index, or does the clutter stay in the index?
• Can archived content still be found, and summarised on demand, when it becomes relevant again?

What good looks like: inactive noise leaves the working set, so Copilot grounds on current, relevant material, and nothing is truly lost.

Red flag: "archived" content that is still indexed is just hidden clutter, not a cleaner tenant.

5. Scope and Granularity

"Archiving" means very different things across vendors. Whole-site archiving is a blunt instrument.

• Can you archive at the individual file/document level, or only entire sites and libraries?
• Can you target content by age or inactivity with rules, or is it all-or-nothing?
• Can you define lifecycle policies that archive content automatically once it meets your rules (for example, untouched for a set period), so cleanup runs continuously rather than as a one-off project?
• Which content types are covered, and which are not (for example OneNote, SharePoint pages, site assets)?

What good looks like: precise, rule-driven, file-level archiving of document-library content.

Red flag: you can only archive a whole site, meaning active and inactive files get swept away together.

6. Cost and Commercial Model

Understand exactly what you are paying for, and whether the model works with you or against you as you grow.

• Does the archived data sit in storage you already control in Azure, or behind a per-GB vendor markup?
• Are there per-user fees, and do they scale in a way that penalises headcount growth?
• Does archiving genuinely reduce your primary SharePoint storage consumption, the thing driving the cost in the first place?

What good looks like: you pay for the service, and your data sits in low-cost Azure storage you already own.

Red flag: pricing that grows with users rather than the problem you are solving.

7. Deployment and Operations

Day-two reality matters as much as the demo.

• What level of access does the vendor require into your tenant to operate?
• Are archive policies rule-based and low-maintenance, or do they need constant hand-tuning?
• Who is accountable for the service running reliably over time?

What good looks like: clearly scoped access, rule-based policies that run themselves, and a vendor that operates the service as a managed offering.

Red flag: broad tenant access with vague justification, or policies you have to babysit.

Scoring Your Shortlist

Tally the "yes / good" answers per vendor. Weight sections 1 to 3 most heavily: restore experience, data ownership, and compliance are the areas you cannot cheaply fix after committing. A tool that is strong on price but weak on data ownership is a false economy.

How Squirrel Answers This Checklist

Squirrel archives inactive SharePoint document-library content into your own Azure storage, using the Cool access tier so it stays low-cost while remaining immediately available. You own and control the data, with no lock-in and no vendor holding the keys. Rule-based lifecycle policies archive content automatically once it meets your criteria, so cleanup runs continuously rather than as a one-off project. Archived files are replaced by a stub in place. Any user (and external guests with library access) restores the original in one click: immediately, with no rehydration wait and no restore fee from Squirrel. Version history, metadata, and permissions all come back intact. Every action is captured in a full audit trail, it is Purview-compatible, and it supports retention and immutable tiers. Add Nutshell and archived content is AI-summarised on demand, keeping Copilot grounded on what is relevant. Squirrel is a managed service: your data always resides in your Azure storage, never ours.

Frequently Asked Questions

Can end users restore archived SharePoint files themselves?

It depends on the tool, and it is the single most important question on this checklist. With stub-based archiving like Squirrel, any user with permission - including external guests with library access - clicks the stub and the original file is back immediately, with version history, metadata, and permissions intact, and no restore fee from Squirrel. With site-level tools, restore is typically an administrator task, which is how archiving projects end up generating help-desk tickets.

Should archived SharePoint data live in the vendor's cloud or our own Azure storage?

Your own Azure storage, if data ownership matters to you. When the archive sits in an Azure storage account in your own subscription, you keep full control and access regardless of the vendor relationship, and the data remains readable with standard Azure tools if you ever stop using the service. When it sits in a vendor's cloud, the vendor is a gatekeeper between you and your own records.

Does SharePoint archiving work with Microsoft Purview retention policies?

It must, and this is worth verifying per vendor rather than assuming. Squirrel operates alongside active Microsoft Purview retention policies and preserves retention and sensitivity labels through the archive and restore cycle. Some platforms document that content under active retention policies is skipped or requires the policy to be removed first - check the vendor's own documentation for this exact scenario before committing.
