retention period

基本解释

Spain has a retention period of one year.
西班牙对数据保留周期是1年。
The user can select a 60-day retention period without approval, or a 90-day period, which generates a request that is routed to an approver who must authorize it.
用户可以选择 60 天的保持期而不需批准，或者 90 天的保持期，但这将生成一个请求发送到批准人，必须经过批准人的批准才可以。
If the user selects a retention period longer than 60 days in the drop-down, an additional field will be displayed for the user to select an approver (see figure 7).
如果用户在下拉框中选择一个大于 60 天的保持期，将向用户显示一个附加的对话框，要求用户选择批准人（参见图 7）。

More important, it trumps Google's own bid to reassure users of their privacy: In September, the search giant cut its data retention period from 18 months to nine months.
