Well yes, you can save the stream to a file, but it is intended for immediate use with "zfs receive". Since the stream is not an image but instead a serialization of objects, normal data recovery methods do not apply in the event of corruption. >> When I attempted to receive the stream onto to the newly configured >> pool, I ended up with a checksum mismatch and thought I had lost my >> data. > > Was the cause of the checksum mismatch just that the stream data >was stored as a file ? That does not seem right to me. I really can't say for sure what caused the corruption, but I think it may have been related to a dying power supply.
