I doubt that this will work - at least not w/o the option "-T directory". See the Command Line Reference for details.
As NW will use absolute pathnames my guess is that it will restore to whatever has been used at the time of the backup.
It might work with save set restores where you can define another destination path. But who wants to use that method ...
We are thinking of doing it in a proccess of restoring client index in a migration of the Networker Server to a new host.
The networker server has the client indexes in several directories now, not in the default path, because the disk was nearly full.
In the restore process we would like to restore to the default index path, so I have tried with one client to set the Index Path empty and then the restore with
nsrck -L7 client
is done to the default index path: networker_installation_path/nsr/index/clientname
We have tried a restore of a file and it works.
So we are thinking in restore all the client indexes to the default path in this manner
Do you see any future issue?
