NoneNone the above (or something close to it) will work.
however, the data will be read and written twice by the
1st (source) `tar', and read twice by the 2nd (sink) `tar',
albeit only written once as the sink realizes the second
copy is a hard link to the first. with c.60Gb of data,
that will make a difference, at least in time and CPU
resource consumed (albeit, in this case, not storage).
the issue here is tar(1) (and cpio(1)) archives always
contain the data for each name of a hard link. this is
(probably) for several reasons, and is not necessarily a
bad thing. e.g., it provides a degree of redundancy to
help cope with bad media.
the source `tar' is creating an archive, which is being
written down the pipe (to be consumed by the sink `tar').
that is why storage is not an issue per se here, as the
full archive is not "saved" --- if it were, you'd need
at least 2x60Gb, or over 120Gb! (the extra is `tar's
overhead, which is minimal but does add up, esp. when
a "large" blocking factor is used.)
cheers!
