Above, the GUI incorrectly base the restore on a copy only backup. After using the timeline dialog to point to an earlier point in time, you can see that the GUI now has changed so it bases the restore on this potentially non-existing copy only backup. Not a nice situation to be in if the person doing the restore hasn’t practiced using the T-SQL RESTORE commands.
It’s important to be able to write the relevant T-SQL queries to restore your database, just in case you run into one of these issues.
