Time Machine can work by backing up to a drive attached directly to a Mac. But Apple omitted a big footnote that should be in its documentation: An APFS-formatted volume can’t be used for networked Time Machine backups. In macOS Big Sur, Time Machine added support for backups onto APFS-formatted volumes (the filesystem that Apple introduced a few releases ago).
