One of the biggest sources of confusion for legal and compliance teams is knowing the difference between in-place preservation and archiving. Both strategies are critical for defensibility, but they serve very different purposes. Treating them as interchangeable can create unnecessary risk, inflate costs, and leave organizations exposed in litigation or audits.
In this article, we’ll break down what each approach means, when to use it, and how Hanzo helps enterprises apply both effectively.
In-Place Preservation: Definition, Benefits, and When to Use It
In-place preservation means locking down data where it lives—ignoring retention policies and preventing deletion attempts—without moving or altering it.
Not all technology vendors support this capability, but leading platforms like Slack, Microsoft, and Google Workspace do, allowing data to remain in its native environment under legal hold.
Why it matters: In-place preservation keeps the full story intact: threads, reactions, edits, deletions, and metadata. This delivers defensibility while reducing manual processes, human effort, and storage costs.
Archiving: Definition, Benefits, and When It’s Required
Archiving involves moving data into long-term, tamperproof storage. Many platforms do not support in-place preservation: for example, Atlassian tools like Confluence and Jira, so the only option is to create an archive or defensible copy.
The benefits of archiving are immutability, centralization, and scalability. Archiving ensures data is locked down for as long as required: whether that means meeting regulatory timelines of seven, ten, or more years, or preserving content under a legal hold while a case is active.
Why the Distinction Matters
Mixing up preservation and archiving creates real legal and compliance risk.
Archiving when preservation is required strips away critical context, weakening defensibility in litigation. On the other hand, preserving when archiving is required can lead to compliance gaps, bloated systems, and retention failures that undermine regulatory obligations.
Regulators such as the SEC, FINRA, HIPAA, and GDPR authorities expect organizations to demonstrate deliberate control over both practices. Missteps can be costly, resulting in penalties, adverse rulings, or long-term reputational damage.
When to Use In-Place Preservation
In-place preservation is the right choice when governance and compliance are strong:
- Litigation holds: When lawsuits are active or anticipated, preserving data in place ensures that the full record remains intact and defensible.
- Investigations: Internal reviews, whistleblower claims, or regulatory inquiries often turn on the context of conversations, not just the text itself.
- Employee transitions: Data from Slack and Teams loses meaning if stripped of threads, reactions, or edits—making in-place preservation essential.
With strong IT governance and clear enforcement of policies, PIP legal holds minimize risk. Without it, errors or ad hoc changes can be costly.
When to Use Archiving
Archiving is the better choice when long-term retention and immutability are required or when SaaS tools don’t support in-place preservation. Failing to archive in these scenarios risks compliance violations and regulatory penalties.
Common use cases include:
- Regulatory compliance: Rules such as SEC 17a-4, FINRA, and HIPAA mandate long-term storage in formats that cannot be altered.
- Audit readiness: Tamperproof, easily retrievable records are essential to demonstrate compliance during regulatory audits.
- Historical reference: Contracts, websites, and marketing content often need to be preserved for years to provide a reliable record of past communications.
- Slack Connect & external channels: Communications with external parties fall outside of Slack’s native preservation practices, making archiving essential.
- Sensitive data protection: When IT governance is limited or errors are likely, archiving prevents accidental deletions of sensitive or business-critical data.
Not all platforms allow in-place preservation (PIP). Only vendors like Slack, Microsoft, and Google support preservation directly in their native environments — and even then, there are gaps. For example, Slack Connect cannot be preserved in place, while platforms like Atlassian (Confluence, Jira), websites, social media, and many SaaS applications don’t support PIP at all. In these cases, archiving or creating a defensible copy is the only option.
Many organizations also choose to archive sensitive content or critical communications as an extra safeguard against administrator error, ensuring nothing is accidentally altered or deleted.
The Risks of Getting It Wrong
Organizations that rely too heavily on one strategy expose themselves to significant risks.
- Over-reliance on archiving reduces records to static files and strips away the dynamic context courts and regulators increasingly demand. The result can be spoliation claims, weakened legal defenses, and evidence that fails to hold up under scrutiny.
- Over-reliance on in-place preservation creates compliance gaps. Without long-term, immutable archives, enterprises risk regulatory violations, ballooning storage costs, and retention failures that undermine governance programs.
Neither approach alone will satisfy the combined demands of regulators, auditors, and the courts. The cost of getting it wrong is measured not just in penalties, but in lost cases, reputational harm, and operational disruption.
The Hybrid Approach
Modern enterprises can no longer choose between archiving and preservation—they need both, working in tandem.
- In-place preservation ensures defensibility in litigation and investigations by capturing conversations, context, and metadata exactly as they occurred.
- Archiving provides the immutable, long-term recordkeeping required for compliance, audit readiness, and historical reference.
When these strategies are aligned, governance shifts from a reactive burden to a proactive strength. Policies become consistent, retention gaps close, and legal holds can be applied with confidence.
