I make it a habit to backup my indexes once a week. I shutdown the legato
services and backup the legato install directory. mIt has saved me once or
twice and is much easier than scanning in hundreds of tapes.
Cheers,
Matt

Re: [Networker] quick file recover help please
There are a couple of quick ways I can think of...
First way, blunt force.... Do a saveset recover of the file....
recover -d /var/tmp/recovertest -S {ssid} {pathspec}
Second way.... Use scanner as per manpages for scanner and uasm to list
the files in the saveset right off the tape....
nsrjb -ln -f {tapedevice} {volume}
scanner -S {ssid} {tapedevice} | /usr/lib/nsr/uasm -rnv | grep
{pathspec}
Using scanner reminded me that what you really should do is fix your
index up after the disk-full corruption ..
scanner -i -S {ssid} {tapedevice}

Thanks for the help... I have a unique situation. I am fairly confident
that the file in question is on the tape; I just can't locate it.
I am a victim of a couple of situations... The night in question, my
filesystem that contained the index got full, so I have no index.
I think that the backup ran successfully that night, but I need to try
to extract a particular file.
How can I find out if the file is on this tape since I have no index?
Thanks again for all the help... the below steps are something I was
not aware of (and this is very usefule!), but it didn't find the file.
Thanks again,
Diane
