Businesses generate more information than they can keep in active systems forever. Emails, contracts, financial records, project files, and communication histories continue to accumulate long after their immediate usefulness fades.
Deleting this information can create legal and operational risks. Keeping everything in expensive primary storage creates another problem.
Archiving tools offer a practical middle ground. They move information into managed long-term storage while preserving access, searchability, and retention controls.
The challenge is choosing a platform that protects information without making it difficult to retrieve.
What Are Archiving Tools?
Archiving tools are software solutions that preserve information for long-term access, governance, compliance, or historical reference.
Unlike ordinary storage systems, archiving platforms often include features for retention policies, indexing, legal holds, audit trails, and controlled deletion.
Organizations use them to preserve:
- Business emails and attachments
- Financial and accounting records
- Contracts and legal documents
- Collaboration messages
- Historical project information
- Regulatory records
- Files that are rarely accessed but must remain available
An effective archive should preserve both the information and the context needed to understand it.
For example, retaining an email attachment without its original message may not provide sufficient evidence during a legal investigation.
Archiving vs. Backup: Understanding the Difference
Archiving and backup are related but serve different purposes.
| Feature | Archiving | Backup |
|---|---|---|
| Primary goal | Long-term preservation | Recovery after data loss |
| Typical data | Historical or inactive records | Active systems and data |
| Retention | Policy-driven, often long-term | Based on recovery needs |
| Search | Often detailed and record-focused | Varies by product |
| Legal hold | Common in compliance archives | Not always available |
| Recovery | Individual records or collections | Files, applications, or systems |
A backup protects against accidental deletion, ransomware, and system failures.
An archive supports long-term information management and may help organizations meet recordkeeping obligations.
Most businesses with substantial compliance requirements need both.
Archiving Tools Worth Evaluating
Different products specialize in different types of information. The right choice depends on what an organization needs to preserve.
Microsoft Purview
Microsoft Purview provides data governance and compliance capabilities across supported Microsoft environments.

- Integration with business applications
- Support for complex content environments
Considerations: Buyers should identify the exact OpenText product and deployment model rather than assuming all capabilities exist in one platform.
Features That Matter Most
Retention policy management
Retention policies determine how long information remains preserved.
A useful platform should support rules based on record type, department, legal obligation, and business requirements.
It should also prevent unauthorized deletion when records are subject to legal holds.
Search and retrieval
An archive provides limited value when employees cannot find information.
Evaluate full-text search, metadata filtering, attachment indexing, and export capabilities.
Test retrieval using real historical records rather than relying on demonstrations.
Integrity and tamper resistance
Some organizations must demonstrate that preserved records have not been altered.
Look for appropriate integrity controls, access restrictions, audit logs, and immutable storage options where required.
A vendor’s use of the term immutable should not replace a technical review of its actual guarantees.
Data security
Archived information may contain sensitive customer, employee, or business data.
Evaluate encryption, identity integration, role-based access, administrative separation, and security monitoring.
Data portability
Moving away from an archiving vendor can become difficult when information is stored in proprietary formats.
Before signing a contract, test whether records, attachments, metadata, and audit information can be exported in usable formats.
How to Choose an Archiving Platform
Start by identifying the information that must be preserved.
An organization archiving Microsoft 365 email has different requirements from a financial institution preserving regulated communications.
Next, establish retention periods and legal obligations with the relevant compliance team.
Then compare vendors using a realistic test:
- Import representative records.
- Apply retention policies.
- Search for specific information.
- Place selected records under legal hold.
- Export records with their metadata.
- Test administrator permissions and audit logging.
The test should include difficult cases, such as large attachments, deleted source accounts, and unusual file formats.
Common Archiving Mistakes
One mistake is treating inexpensive storage as a complete archiving solution.
Low-cost object storage can preserve files, but it does not automatically provide defensible retention, record indexing, or compliance workflows.
Another mistake is retaining everything indefinitely.
Unnecessary retention increases storage costs, privacy exposure, and discovery complexity.
Organizations should also avoid assuming that an archiving platform automatically guarantees regulatory compliance.
Compliance depends on policies, configurations, procedures, and applicable laws.
Final Thoughts
The best archiving tool is not necessarily the platform with the longest feature list.
It is the system that preserves the right information, protects its integrity, and makes authorized retrieval dependable.
Microsoft Purview is a logical starting point for many Microsoft-centric organizations. Mimecast deserves consideration for email-focused needs, while Smarsh addresses specialized communications compliance requirements.
Larger enterprises may also evaluate Veritas Enterprise Vault and relevant OpenText solutions.
The final decision should come from real retention requirements, tested retrieval workflows, and a clear understanding of long-term ownership costs.
A well-designed archive does more than preserve old information. It helps an organization retain control over its institutional memory.
