Some NetBox models support automatic synchronization of certain attributes from remote [data sources](../models/core/datasource.md), such as a git repository hosted on GitHub or GitLab. Data from the authoritative remote source is synchronized locally in NetBox as [data files](../models/core/datafile.md).
A user must be assigned the `core.sync_datasource` permission in order to synchronize local files from a remote data source. This is accomplished by creating a permission for the "Core > Data Source" object type with the `sync` action, and assigning it to the desired user and/or group.
