time machine could not create a local snapshot to back up from
I'm trying to back up, but it won't do it. It gives me the following message:
iMac 27", macOS 10.14
Is your internal HD or ssd nearly full?

“Your Mac counts the space used by snapshots as available storage. Even so, Time Machine stores snapshots only on disks that have plenty of free space, and it automatically deletes snapshots as they age or as space is needed for other things.”
