Hi Terry, Thanks for the info. The "save" process is the process that has the
CPU pegged.
>From a ps -ef variant:
root 972551 972549 97.0 Jul 18 ?? 21:03:55
/usr/opt/networker/bin/save -s nfs-a.jtc.jcvsf.org -g ArchiveGroup -LL -m
nfs-a.jtc.jcvsf.org -l full -q -W 78 -N /export/jtc/archive /export/jtc/archive
The nsrindexd doesn't appear to have done much since I started this backup
yesterday morning.
root 972552 709563 0.0 Jul 18 ?? 4:55.35
/usr/opt/networker/bin/nsrindexd -a ADD nfs-a.jtc.jcvsf.org index for backup on
nfs-a-1.jtc.jcvsf.org
Thanks,
Randy
