+If a custom schedule is selected, any section not specficed will be considered to be "any" (aka: wildcard).
+I.e. if Day of Month is set to 12 and Day of Week is not set, the Backup will be run on ANY 12th of
+the month - regardless of the day of the week. If Day of Week is set to, say, Monday, the Backup will run ONLY
+ on a Monday, and ONLY if it's the 12th of the month.
