7-day history

Is your 7-day history working properly? In all three of my SP accounts I'm seeing a situation like seen in the screenshot attached.

Also I've been getting notifications saying:

Backup status is unknown
 
The backup agent was offline at a scheduled backup time. The status of the device backups will be unknown until the backup agent becomes online.

but backups are actually working fine.

Anyone else seeing the same?
