thats easy Rick

in Your debug library / folder or whatever you want to call it.

NT it is normally c:\nsr\debug , on Unix it is normally /nsr/debug

in this location you make an empty file (touch in unix)

file name should be , striped_recover

no extensions , thats it.

Osvaldo

Asunto: [Networker] large filesystem restores


environment: solaris 5.8, networker 6.1.1

in order to speed up backups on a large filesystem, directories are
arranged as follows:
  /export/home/home0
  /export/home/home1
  ...
  /export/home/home9

this permits full backups to be spread over several nights. fine.

last week we had to restore the filesystem. the person doing it used
recover and simply started a single recover at /export/home. as could
be predicted, this took a long time. the main bottleneck appears to
have been the single restore thread using a single tape drive at a
time. presumably we could have saved time by starting (say) two
recovers at once, manually spreading them over the directories to be
restored.

the question is: is there any way to tell legato to (automatically)
use more devices for a restore? is there any way to get recover to be
a bit smarter wrt resource utilization?
