How do you recover the managed data? What about the original machines?

If the TiUP machine is deleted, redeploying it should work, but the machines it originally managed probably can’t be managed directly anymore because the related metadata is missing. You might need to restore the relevant metadata to achieve that.

See if you can still find the .tiup directory, check what contents are inside, and whether there is still a meta.yaml file.

Install tiup and construct the original meta.yaml file (only roughly).
