Backing up iPhone directly to external hard drive?

Is there a way to back up an iPhone 8 Plus directly to an external hard drive on a late 2013 iMac? There isn’t enough room on my computers hard drive and so I am forced to delete a lot of things just to do the backup.

If you drive is so full you don't have space for an iPhone backup, it's too full to operate efficiently and error free.


You need to have 15-20% of the drive totally unused at all times for the OS to operate properly.

You can also back up to iCloud. The first 5GB is at no added cost, and that is plenty of space for an iPhone backup.

I'm able to backup my iPhone to an external drive but it was setup way back under iTunes. With Ventura I haven't found the menu/or button that lets me setup the location.


You[re best bet with an iMac is to move the contents of your Pictures folder to a folder (Pictures-2) on the EHD and operator them from there. You can also move your Music/iTunes library to the EHD (Music-2) to free up a lot of space. Then add those folders to the Finder sidebar so they are easily accessed.


NOTE: the EHD must be formatted either OS X Extendeed (journaled) for HDDs or APFS for SSDs.

FYI for future readers, while iMazing backups can be located on any drive, iMazing requires and uses the ordinary iPhone backup files that are in the default Mac location (~/Library/Application Support/MobileSync/Backup), so you don't actually free up any space on your main drive by using iMazing.


It may be possible to create a symlink at ~/Library/Application Support/MobileSync/Backup that points to your external drive so iPhone backups are written to the external drive instead of your internal drive. But I have not yet tried that method. It may or may not work. (For me, using a symlink worked for Mac Mail but not for my Outlook profile, so I have not tried it for iPhone backups.) Note also, in my experience, symlinks have become progressively more difficult to do successfully with each release of macOS since High Sierra.
