# Synthetic Full Backup Settings

To specify synthetic full backup settings for the backup job, do the following:

1. In the **Specify advanced job settings** window, select the **Synthetic full** option with the [Tab] and [Down] keys and press [Enter].
2. In the **Synthetic full** window, make sure that the **Create synthetic full backups periodically** option is highlighted and press [Space].

   ::: note

   If you plan to use a GFS retention policy, you must configure periodic synthetic or active full backups. Otherwise, Veeam Agent will not have full backups to mark with GFS flags. To learn more, see [Long-Term Retention Policy](gfs_retention.md).

   :::

3. Use the **Monthly on** or **Weekly on selected days** settings to define the schedule for periodic synthetic full backups. You can configure a monthly schedule to run synthetic full backups on a specific day of the week on specific months or a weekly schedule to run synthetic full backups on a specific day of every week.
