Start with the source
eDiscovery Collection begins with understanding how the source stores information. Modern platforms may contain messages, files, edits, reactions, versions, permissions and linked content that cannot be represented faithfully by a screenshot or a simple file copy.
Define collection scope
Connect custodians, systems, date ranges and data types to the issues in the matter. Preservation can be broader than collection; collection can be staged and targeted when that is proportionate and defensible.
Choose the acquisition method
Options can include native exports, APIs, specialist connectors, endpoint tools, targeted file collection and forensic acquisition. Record the method, authentication used, filters applied and any limitations imposed by the platform.
Preserve metadata and relationships
Maintain relevant timestamps, sender/recipient fields, file properties, parent-child relationships, thread or channel context and source identifiers where they affect meaning or later processing.
Security and privacy
Minimise unnecessary personal or irrelevant data where possible, use secure transfer and storage, and coordinate cross-border or sensitive-data issues before moving large datasets.
Validation
Compare expected sources with collected outputs, record counts, review exceptions, check representative samples and reconcile failed or partial collections. Validation is particularly important when cloud exports or APIs impose limits.
Documentation
Collection logs should allow another practitioner to understand what was collected, from where, by whom, when, how and with what result. Record material deviations and remediation.
Practitioner takeaways
- Start with the legal or investigative objective.
- Use methods proportionate to the data, risk and deadline.
- Preserve context and metadata where they affect meaning.
- Validate important outputs and exclusions.
- Document material decisions so the process can be explained.
