SharePoint Archiving vs Deletion: Which Is Safer?
When it comes to managing data in Microsoft 365, IT administrators face a critical question: should we delete old files to save space, or archive them for future reference? While deletion may seem like the fastest way to reduce clutter, it carries risks that organizations often overlook. Archiving, on the other hand, provides long-term protection and compliance benefits. Let’s break down the differences and why it matters for businesses using SharePoint Online.
What Is Deletion in SharePoint?
Deletion in SharePoint means permanently removing a file or folder. Microsoft provides a two-stage Recycle Bin:
-
Stage 1: End-user recycle bin (93 days retention).
-
Stage 2: Site collection recycle bin (also 93 days, shared quota).
Once both stages expire or are emptied, the file is gone unless you have a third-party backup or hold policy.
Risks of Deletion
-
Data loss: Once gone, recovery options are limited.
-
Compliance failure: Regulatory audits often require access to historic records.
-
Human error: Users may delete the wrong files.
Deletion frees up storage, but it’s risky when compliance or litigation is a factor.
What Is Archiving in SharePoint?
Archiving is the process of moving inactive or less frequently accessed data to a secondary, cost-effective, and secure location while keeping it accessible for future use.
Unlike deletion, archiving ensures the data still exists, but in a managed, low-cost tier. In SharePoint, true archiving isn’t built-in — you either rely on retention policies or third-party solutions like Squirrel.
Benefits of Archiving
-
Compliance: Keep historic data for audits, investigations, or legal holds.
-
Cost savings: Reduce expensive SharePoint Online storage costs by moving older files to cheaper storage tiers.
-
Performance: Keep active libraries lean, improving search and sync speeds.
-
User access: Archived items can remain discoverable with stubs or search.
Archiving vs Deletion: Key Differences
| Factor | Deletion | Archiving |
|---|---|---|
| Data availability | Permanently removed after retention | Retained long-term in secure storage |
| Compliance | Risk of non-compliance | Meets audit and legal requirements |
| Cost | Frees up space but may cost later | Optimized storage, predictable costs |
| Recovery | Limited once recycle bins expire | Easily restored when needed |
| User experience | Data gone, may disrupt workflows | Data appears as stubs or searchable |
Why Deletion Alone Is Risky
For IT managers under pressure to control costs, deletion seems like the obvious answer. But regulators (GDPR, HIPAA, SOX, Essential 8, NIST) often require long-term data retention. Deleting files prematurely can lead to fines, legal exposure, and reputation damage.
Moreover, when a business user comes back asking for “that old project file from two years ago,” deletion leaves IT without options.
Why Archiving Is Safer
Archiving gives you the best of both worlds: reduced storage in production SharePoint and the assurance that data is not lost. With solutions like Squirrel, you can:
-
Automatically move files older than X months/years.
-
Replace them with lightweight stubs so users can restore on demand.
-
Keep data in low-cost Azure Blob storage but still under your Microsoft 365 tenant.
This balances compliance, cost control, and user experience.
Conclusion
When it comes to managing SharePoint data, deletion might save space quickly, but it creates long-term risk. Archiving provides a safer, more strategic approach — keeping costs down while meeting compliance and business needs.
If your organization is struggling with ballooning SharePoint storage, it’s time to consider an archiving strategy. Squirrel was built specifically to solve this challenge.
FAQs
Q: Can you archive documents in SharePoint Online without third-party tools?
A: Not natively. SharePoint has retention and deletion policies, but no true archiving function. Files are either kept in place or deleted.
Q: Does deletion free up space permanently?
A: Yes, but only after the recycle bin retention period (93 days). Before that, deleted files still count towards your storage quota.
Q: What’s the difference between retention policies and archiving?
A: Retention policies prevent deletion for a set time but do not reduce storage costs. Archiving moves data to a cheaper, long-term tier while keeping it accessible.
Q: How does Squirrel improve SharePoint archiving?
A: Squirrel automatically archives files to Azure Blob storage, replaces them with stubs, and ensures compliance by keeping everything under your Microsoft 365 tenant.
