Question. Are the source file system's checksums (and metadata) preserved in the send file? Or does the send file just contain data, and checksums are recomputed on receive? I'm curious if the send file can be stored on a non-checksumming file system, and yet have a means to verify the integrity of the files once received. Either the checksums in the send file being check during receive, or subsequent to receive completion by using scrub? And yes I can confirm that send outputting to a file on a 2nd drive, and receiving it to yet another drive does work, and the source and destination subvolumes are the same in seemingly every way. I didn't separately rsync checksum compare the two subvolumes, however. That seems like possibly a good test. I also haven't tried doing it over a network.
