How did you restore?
If you only restored an aspect directory backup, trends and events from the past will not appear.
Saving data from the Event Storage (events) and Basic History (trends) services are separate options during backup.
You might be able to "inject" this data into the system from an image backup (disable the services and replace their folders below (...\\OperateITData\...) and then enable them again).
Alarm state can not be saved in any backup.
