The life span of campaign data is tied to the concept of campaign termination. Upon termination, campaign data is archived and in some cases purged. Currently archived data is restored upon un-termination of a campaign.
Campaigns will automatically be terminated 3 months after the campaign end date. The exception is Campaign Bundle campaigns, which are terminated 6 weeks after end date.
If in need to access archived data, please contact your account manager.
