Does Time Machine need hard drive empty?

A general “rule of thumb” is, to keep a reasonable “depth” of backups, Time Machine needs 2 to 4 times as much space as the data it’s backing-up (not necessarily the entire size of your internal HD). Be sure to add the size of the data on any other drives/partitions you want to back up.

What to do when time machine says there is not enough disk space?
