What Is Data Sync?
Data synchronization (data sync) is the continuous or scheduled process of ensuring that data in two or more systems remains consistent. When data changes in one system, those changes are automatically reflected in all connected systems.
The process of maintaining consistent data across multiple systems by automatically propagating changes.
Data sync ensures your team always works with current information, regardless of which tool they use. When a sales rep updates a contact in the CRM, that change automatically appears in the marketing platform, support tool, and billing system.
There are two main sync approaches: one-way sync (changes flow from a primary source to secondary systems) and two-way sync (changes in any system propagate to all others). Two-way sync is more powerful but requires conflict resolution — what happens when the same field is updated in two systems simultaneously?
Real-time sync propagates changes instantly (typically via webhooks), while batch sync runs on a schedule (hourly, daily). The right approach depends on your needs: customer-facing data usually needs real-time sync, while analytics data can often be batched.
Automation platforms simplify data sync by handling the complexity of change detection, conflict resolution, data transformation, and error recovery. You define what data should stay in sync between which systems, and the platform manages the rest.
