APS wait-to-restore time database APS倒换恢复时间库
Now, it is time to backup the database from your primary machine and restore it on the standby.
现在，我们可以从主要计算机上备份数据库，并将其还原到备用计算机上。
By doing so, there is no need to restore the data into a live database, which provides greater flexibility and saves time and cost on resources to restore the data to a database.
完成这些步骤之后，就不必将数据存储到活动数据库中，从而提供更大的灵活性，并且节省了将数据储存到数据库所需的时间和资源成本。
The backup may be an online operation, but the restore is offline and the time that the database is unavailable may be unacceptable given your availability requirements.
备份操作可以在线完成，但恢复操作是离线的，而且其间数据库不能用，如果有可用性要求，那么这种情况是不可接受的。
