Can anyone point me to a template resource or report that can show me devices not backed up in x days?
Something like this?
SELECT MAX(DayDiff(DownloadTime, GETUTCDATE())) AS DaysSince, NCA.NodeProperties.Nodes.Caption
FROM NCM.ConfigArchive NCA
GROUP BY NodeID, NCA.NodeProperties.Nodes.Caption
HAVING (MAX(DayDiff(DownloadTime, GETUTCDATE())) > 90)
ORDER BY DaysSince DESC, NCA.NodeProperties.Nodes.Caption
Just add it to a webpage by adding a Custom Query resource and putting this Query in there. Or load it up with SWQL and execute it there.
You could use the builtin NCM report called "Backup Status of Startup Config. Then export it to Excel and sort on the Last Startup Backup column.
But the above solution would probably work easier.
