Builds in at the destination.

Remember (if you are old enough!) that tar means Tape ARchive, and
that tape drives are sequential devices and also that Way Back When
tape drives were cheaper than disk drives.

(Even now, LTO3 400/800GB tapes are less than US$35, whereas SATA
400GB drives are US$100 at NewEgg.  Much more when you buy from a
Tier 1 vendor.  And I'd rather drop a tape than a hard drive.)
