Simple answer, No advantage of restoring an older full backup and then restoring another newer backup on top of that.简单的答案，恢复较旧的完整备份然后在此基础上恢复另一个较新的备份没有任何优势。 Your restore of the newer full backup will overwrite the restore of the older backup.您对较新完整备份的还原将覆盖旧备份的还原。
Disadvantages: Simply waste of time and recourses.缺点：简单地浪费时间和资源。

在旧的完全备份之上恢复新的完全备份将覆盖旧的备份恢复。
