Thanks . . .

Grrrrrrr . . . I figured out what is happening.  The files that are backed
up are unix compressed (foo.Z).  The dsm.sys file is set with "compression
yes".  Of course the cpu is spinning, it's uncompressing the file which is
already compressed!!!!

Hi,
you may try instead
dsmc restore "/oracle/backup/fedwp1/bkup.hpdw1p.200903081920.fedwp1.hot/?*"
/oracle/backup/paul/ -inactive -subdir=yes -replace=no

This would deactivate the nqr -feature and we use it often when restoreing
quite small
number of files out of bigger file-spaces.

regards
Rainer
