I have noticed that when I reboot my computer the Icon (Lower Right) turns Red. Status before this happens says checking disks. After it goes Red the Status indicates there is a problem with the Backups. If I double click on the Icon it opens to the Home screen then rescans the disks and says that everything is OK. After closing the Icon turns White/clear. It is just a nuisance every time I boot my computer to have to click on the icon, wait while it opens to the Home Screen and finally shut it down.
I rely on the Icon to let me know if I missed a backup.
