Symantec System Recovery tray icon status is incorrect following a missed backup.
Following a missed backup, the tray icon status still shows as 'Backed Up' (green tick) instead of 'Attention Needed' (orange exclamation mark).
If the Symantec System Recovery 2011 user interface (UI) is opened, the tray icon status is correctly updated to 'Attention Needed'.
NOTE: In Symantec System Recovery Management Solution 2011 (SSR-MS) environments, this may cause client machines to show the incorrect status in the management console which in turn means that missed backups are not obvious to the administrator.
At the time of writing, there is no workaround to this issue.
