can pbzip2 run on stdout?

["Stefhen Hovland" <stefhen.hovland@gmail.com>]

Is this possible for pbzip2  to run on a tar which outputs to standard out?

I am trying to speed up a backup process which takes hours, i have
about 100g of uncompressed data which will be tar'd up and is
currently running thru gzip. This will be running on a 16 cpu box
which would greatly speedup this issue.

from:

tar cf - . | gzip > /tmp/file.tar.gz

to:

tar cf - . | pbzip2 > /tmp/file.tar.bz2


This doesnt seem to work, is it because there is no way to split the
stdio to multiple processors on the fly?

Thanks for your help, I'm not subscribed to the list so if you could
cc: me in addition to the list that would be great.


Thanks,
Stefhen
