# Instance Sync

You can synchronize the available EC2 instances and ECR repositories and images in multiple regions across multiple accounts. This includes:

- Creating EC2 instances as assets in Nucleus with all of the associated instance metadata.
- Creating images in repositories for which there are no available scans.
- Synchronizing AWS resource tags and container image tags for mutable container image repositories.
- Automatically deactivating or removing EC2 instances and ECR container images in Nucleus if they have been terminated in the corresponding AWS account or ECR repository.

          Warning

          

We strongly recommend that you **only** sync and ingest data from regions which are expected to have assets and scan data. If you select every region, the connector will take longer to process as discrete API calls need to be made to each region per AWS account.

## Set up instance synchronization

          Asset Correlation Note

          

This connector automatically correlates EC2 instances from AWS with assets created from vulnerability scan tools such as Tenable.io, Qualys VM, or Rapid7 Nexpose to ensure that assets are not duplicated.

1. From the navigation bar on the left, select **Automation**.
2. Select the **Asset Inventory Sync** tab.
3. Click **+ Add Rule**.
4. In the **Name** field, enter a name for the rule.
5. From the **Select the connector from which you would like to import assets** menu, select the AWS connector you created previously.
6. Click **Next**.
7. Select **Amazon EC2** or **Amazon ECR**.
8. Click **Next**.
9. Select the region(s) from which to sync assets.
10. Click **Next**.
11. Select the account(s) from which to sync assets.
12. Click **Next**.
13. Select which assets to import.
  - To import all assets, select **Apply to all assets**.
  - To import specific assets, select **Only import assets which match the criteria** and configure [asset matching rules](/v1/docs/asset-matching-filters) to define which assets to import.
14. Click **Next**.
15. In the **Start Date** field, enter or select a date to begin synchronizing assets.
16. In the **Start Time** field, select the time of day for assets to synchronize.
17. Click **Save & Finish**.

## Next steps

After setting up instance synchronization, proceed with configuring the AWS connector to pull data from any of the following AWS services: - [Inspector 2 (EC2 Continuous Scanning) via Security Hub](/v1/docs/inspector-2-ec2-continuous-scanning) - [ECR (Enhanced Scanning) via Security Hub](/v1/docs/ecr-enhanced-scanning) - [Inspector Classic](/v1/docs/inspector-classic) - [ECR (Basic Scanning)](/v1/docs/ecr-basic-scanning)
