Nope.
There is an MCC command for it though: 20011 MCC_BACKUP_LIBRARY int nMode (0: normal, 1: silent automatic backup)
So you could use the MC Scheduler to run a backup as much as once a day, at a time you select, using the command;
mc24.exe /MCC 20011,0
or
mc24.exe /MCC 20011,1
I'm not sure which would work best.
You could also use the Windows Task Scheduler if you preferred that.
