The Show-LastServerBackup function iterates through each database on the server and takes each of the three properties mentioned in yesterdays post. However this time I created an empty hash table and added each result to it as follows

I created the hash table with @() and then assign each property to a variable inside the loop and add it to a temporary PSObject with some custom NoteProperties to fit the data
