I'm unaware of this kind of best practices advice (and can't find it on the ZFS Best Practices Guide wiki page). The only thing that remotely resembles this kind advice is this paragraph: "If you store ZFS send stream on a file or on tape, and that file becomes corrupted, then it will not be possible to receive it, and none of the data will be recoverable. However, Nevada, build 125 adds the zstreamdump(1m) command to verify a ZFS snapshot send stream. See also, RFE 6736794." That would be true even if the filesystem on which the snapshot is stored becomes corrupted (due to being stored on a single-device vdev, for example).
