Jul 8, 2016 at 21:02 comment added Thomas Dickey Actually, a tar program could be written to both read/write in parallel, since the output archive is not compressed, and because the size of each file (and header) can be computed directly (allowing a program to write a different extents). There aren't a lot of applications which need that, however.
Jul 8, 2016 at 20:55 comment added Satō Katsura Not with standard tar. tar stands for Tape ARchiver, once upon a time it was used to write backups on tapes (it still can do that, if you have the hardware). The physical format was exactly the tar format (or rather pax). Since you can't write things in parallel on a piece of tape, tar can't archive files in parallel. Maybe newer incarnations of it can though. On a side note: the format has rather low limits on paths length. Make sure you don't run into those before trying to archive 8 mil. files.
