Mechanics - Backup And Restore
All drives will eventually fail. If the drive goes, the data on it goes. M1 makes it easy to protect your library data. One backup system is done automatically each day you use M1. This is an on-board backup, a clone of your library file kept on the same drive as the master file. The other backup is something you must do yourself. That is to copy your .m1 library file to another drive or to a cloud folder.
