ZFS send streams consist of records which describe writes or frees the receiving end should perform in order to recreate the sent snapshot. For example, a WRITE record could indicate that the contents of the 5th block of the file with object number 1534 should be updated. A very simple send stream is depicted below. When generating this stream the records are written to a file descriptor. When using the zfs send command this file descriptor is stdout. | ZFS send streams consist of records which describe writes or frees the receiving end should perform in order to recreate the sent snapshot.
