About backups in iCloud and iTunes - Apple Support

The following article gives a decent summary of what is, and what isn't, backed up in iCloud and iTunes. To me, this is a bit confusing. Some things are backed up, some aren't. I do back up to iCloud, but also use a complete backup (a complete clone) of everything on my Mac to an external hard drive. This way, I know I've got everything. There are several good programs one can use to do this, and I use Super Duper. Fortunately, I've never had to use it to recover from a hard drive failure. May it ever continue so. Jim Hamm
