# Full Data Re-Sync

Dataddo's **Full Data Re-Sync** feature loads **all historical data** from a connected **source** to [storage](/docs/data-storages){target="_blank"} solutions like [BigQuery](/docs/google-bigquery){target="_blank"}, [Snowflake](/docs/snowflake){target="_blank"}, or [Databricks](/docs/databricks){target="_blank"}. This makes your data storage comprehensive, including both current and past data, improving your analytics and reporting capabilities.

Some common use cases for full data re-sync are:
* Recovering lost data
* Backfilling historical data
* Fixing past sync issues

:::(Info) (**DATADDO TIP**)
See the [Full Data Re-Sync video tutorial](/docs/full-data-re-sync#video-tutorial).

## Prerequisites
Before using the **Full Data Re-Sync** feature, ensure the following conditions are met:
* **Compatible Data Destinations**: To maintain data consistency, the feature is only available for destinations that support **{{glossary.upsert}}** mode (e.g., databases, data warehouses like BigQuery, Snowflake, or Databricks).

## The Process
To start the full data re-sync, on the [**Flows**](https://app.dataddo.com/flows){target="_blank"} page, [trigger the extraction](/docs/data-backfilling-to-storages#trigger-the-extraction) and select your date range. Dataddo then manages the sync process while handling any limitations set by the data source. For example, large requests are automatically split into smaller jobs to comply with API restrictions.

Users can oversee re-sync jobs through a dedicated dashboard, ensuring transparency and control.

:::(Info) (**DATADDO TIP**)
**Full Data Re-Sync** runs separately from regular syncs to prevent disruptions to ongoing data pipelines.

Large datasets may take longer to process.
