Cannot finish the backup before my journey begins. Since ist started two days back, it is now at 35%. What a ..

This happens on my MacBook Pro with current macOS Sequoia 15.5.

I've been trying with two different external USB hard drives, including a brand new one.

Come on, Apple.

Not just TM, the OS needs that at all times, they should make it more well known that free space is not ours alone, nor free… also if you could run it with 8 GB FREE the SSD would die 4 times faster than with 32 FREE.
