My wife has a MacBook Pro (13-inch, 2017) with 256GB SSD. She recently purchased a iPad Air 4 256 GB.

She (unsurprisingly) can't backup her iPad to the MacBook as it requires 60GB.

Is it possible to backup to a USB HDD?

If so how?

I finally got around to trying (realistically I was allowed to access my wife's laptop) the suggestion below. Unfortunately I can't seem to access the MobileSync directory.

I had previously checked on my iMac but I have disabled SIP.

Even using sudo won't let me access the directory and results in "operation not permitted" although most of the other directories are accessible.

Any other suggestions?

  1. Delete or rename the old backup folder located there: ~/Library/Application Support/MobileSync
  2. Create new backup folder on your USB HDD
  3. Create link by the following terminal command (replace path with the path to your new backup folder): sudo ln -s "PATH" ~/Library/Application\Support/MobileSync/Backup
