- On a regular copy (10.15 and before on APFS), they're just normal files. I explain why here - http://www.shirt-pocket.com/blog/ind...aternal_twins/ However, on Big Sur, an erase-then-copy backup uses replication which will preserve the clones. Subsequent Smart Updates might or might not increase the cloned file sizes, depending on what files were affected, and how.
- It'll be the current state of the files unless a source snapshot is selected.
- We include and maintain them automatically. There's no need, in Catalina or earlier, to install.
- No, but see Big Sur comment above.
