Backing Up iPhones and iPad to External HDD
This question applies to a 2018 Mac mini operating macOS Ventura 13.2. I am also using an iPhone Xr, an iPhone 13, and an iPad Pro (12.9-inch) (3rd generation), all of which are on iOS 16.3.
Instead of following the traditional way of backing up the iPhone and iPad to the interall SSD on the Mac mini (How to back up your iPhone, iPad, and iPod touch with your Mac - Apple Support), what is the best way to save the backups directly to an attached external HDD?
I have seen a lot of information on terminal commands, but is there an easier way to execute the backup, such as with an alias link (Create and remove aliases on Mac - Apple Support)? I tried going the alias path, but my aliases (even though they should have wroked) didn't work - they saved the backups on the internal SSD and not the external HDD.
Mac mini, macOS 13.2
