Hi Kees,
maybe you can try to split up the files into several DLEs and put them
into different spindles. That should fire off multiple instances of tar
in parallel, if I understood Amanda's concept of spindles correctly.
Hope it helps,
Jens

Hi list,
We've got some backup targets with lots (and lots, and then some) of
files. There's so much of them that making back-ups is becoming a problem.
During the backup process, tar(1) is eating up a CPU core. There's no or
hardly no I/O wait to be seen. Very likely tar is single threaded so
there's that. The additional gzip(1) process is doing zero to nothing.
Any thoughts on speeding this up? Maybe an alternative for GNU tar, or...?
Thanks all!
Cheers,
Kees
