After restoration of a backup created using {% data variables.product.prodname_enterprise_backup_utilities %} {% ifversion ghes = 3.9 %}3.7.0, 3.8.0, or 3.9.0{% endif %}, users may not be able to sign into the instance. To fix this issue, plus a bug that was preventing secret scanning encryption keys from being backed up, upgrade your backup host to use {% data variables.product.prodname_enterprise_backup_utilities %} {% ifversion ghes = 3.9 %}3.9.1{% endif %} and generate a new full backup using ghe-backup. For more information on using an existing backup, see "AUTOTITLE."
