Introduction
Archiving Tools are specialized software solutions designed to identify, move, and store inactive or historical data in a long-term, secure, and searchable environment. Unlike standard backup tools, which are meant for quick disaster recovery of current data, archiving tools are built for “data preservation.” They remove older files, emails, and messages from primary storage—where space is expensive—and place them into a secondary storage tier that is optimized for cost-efficiency and legal discovery.
The importance of these tools has grown exponentially alongside the rise of data regulations and the sheer volume of digital communications. Archiving is critical for Regulatory Compliance, allowing companies to meet retention laws like FINRA, SEC, and HIPAA. It is also a cornerstone of eDiscovery, enabling legal teams to find specific documents from five years ago in seconds rather than weeks. Key use cases include email offloading to speed up server performance, social media archiving for government transparency, and legacy system decommissioning. When choosing a tool, users should prioritize search speed, data immutability, automatic retention policies, and broad integration with communication platforms.
Best for: Legal departments, Compliance Officers, and IT Managers in highly regulated industries like Finance, Healthcare, Government, and Legal Services. They are essential for mid-market to enterprise-level organizations managing vast amounts of unstructured data.
Not ideal for: Individual users or micro-businesses with minimal data footprints. If your data retention needs are satisfied by a simple external hard drive or basic cloud storage (like a personal Dropbox), the high cost and complexity of enterprise archiving tools are likely unnecessary.

Which Archiving Tool Is Right for You?
Solo Users vs SMB vs Mid-market vs Enterprise
- Solo Users: Generally do not need specialized archiving. Use the built-in “Archive” button in Outlook or Gmail to keep your inbox clean.
- SMB (10–100 Users): Barracuda or Microsoft Purview (if already on M365) are the most sensible choices. They provide the basic compliance needed without a massive price tag.
- Mid-market (100–1,000 Users): Mimecast or Proofpoint are excellent. They offer faster search and better legal tools for companies that deal with occasional litigation.
- Enterprise (1,000+ Users): Smarsh, ZL Tech, or Global Relay are built for this scale. They can handle the massive volume and complex global regulations of a multinational bank or agency.
Budget-conscious vs Premium Solutions
If you are strictly watching the bottom line, using the Microsoft Purview features already included in your license is the best path. If you need “premium” features—like the ability to search across every WhatsApp message and Zoom transcript in under a second—Smarsh and Mimecast are the premium gold standards.
Feature Depth vs Ease of Use
If you want a tool that a lawyer can use without calling IT, PageFreezer and Proofpoint have very friendly interfaces. If you need “depth”—meaning the ability to perform complex data mining and privacy cleanup—ZL Tech offers the most power, though it requires more expertise.
Integration and Scalability Needs
For companies that are “All-Microsoft,” Purview is the logical home. However, if your company uses a “best-of-breed” stack (Slack for chat, Zoom for video, Salesforce for CRM), you need a third-party archiver like Smarsh to bring all that data into one place.
Frequently Asked Questions (FAQs)
1. What is the difference between Backup and Archiving?
Backup is a temporary copy of data used to restore a system after a crash (usually kept for 30–90 days). Archiving is a long-term storage strategy for data preservation (usually kept for 7–10 years) with a focus on searchability and legal compliance.
2. Why can’t I just use a large external hard drive?
For business compliance, data must be stored in a way that is “immutable” (cannot be changed) and “searchable” (has an index). A hard drive provides neither and doesn’t offer the “chain of custody” logs required in court.
3. Does archiving email make Outlook run faster?
Yes. By moving old emails and large attachments out of the primary mailbox and into an archive, the “mailbox database” becomes smaller. This leads to faster sync times and fewer crashes in Outlook.
4. How long am I legally required to keep archives?
It depends on your industry. Most U.S. businesses are required to keep tax records for 7 years. Financial firms (SEC/FINRA) often have 6-year requirements, while healthcare (HIPAA) can require up to 50 years for certain records.
5. What is “Litigation Hold”?
A litigation hold is a feature that overrides your normal deletion rules. If an employee is involved in a lawsuit, you can place a “hold” on their archive so that even if a rule says “delete after 7 years,” their data is saved until the legal case is over.
6. Can these tools archive deleted messages?
Yes. Enterprise archivers “journal” data. This means a copy of the email is sent to the archive at the exact moment it is sent or received. Even if the user deletes it from their inbox a second later, the copy is already safe in the archive.
7. Is cloud archiving safer than on-premise?
Generally, yes. Cloud providers use “triple redundancy” (storing data in three different places) and high-level encryption that is difficult for a small IT team to maintain on their own servers.
8. Can I archive my company’s social media?
Yes, tools like PageFreezer and Smarsh specialize in this. They capture not just the text, but the context, images, and even the “likes” and comments, which can be important for marketing compliance.
9. What happens to the archive if I switch providers?
Most vendors allow you to export your data in a standard format (like PST or EML). However, “egress fees” can apply, so always check the data portability section of your contract.
10. Do I need to archive internal Slack or Teams chats?
If you are in a regulated industry, yes. Courts increasingly treat internal chat messages exactly like email. If it’s a business communication, it is usually “discoverable” and should be archived.
Conclusion
Choosing an archiving tool is about finding the right balance between legal safety and administrative effort. For most companies today, the goal is no longer just “storing” data, but being able to “find” it.
If you are a smaller firm already on the Microsoft stack, Microsoft Purview is your most cost-effective starting point. If you are a high-growth company using Slack and Zoom, look at Smarsh or Mimecast to ensure those conversations are protected. Ultimately, a good archiving tool should be invisible to your employees but invaluable to your legal team. By moving inactive data to a secure archive, you protect your company from both high storage costs and high legal risks.
