Question: What is a WISS error, and how do I fix it?
newserver:/vd3 1 retry attempted
newserver:/vd3 save: WISS error, too many files created
newserver:/vd3 save: shutdown failed

Answer: You need to run nsrck -F to 'attempt' to fix the error, which generally occurs only when the database grows over 2GB. If this does not work, you then have two options:

1. Delete the index.db and run nsrck -c, this generates a blank index.db for you, and you can then run your backups.
2. Run and mmrecov to restore the last good database. Please run nsrck -F on this database as well, just to make sure everything is clean for Networker.

Question: What is "NetWorker Registration: (warning) License enabler #none (NetWorker/10 Eval) will expire in 10 day(s)."

Answer: This means that you have installed nsrd (the networker server daemon) without registering it and it's eval time peroid is almost up. This usually is produced by a client, not a server, running nsrd. Since clients dont need to run nsrd, you should remove or chmod the executable and change your rc scripts so that it does not try to start up anymore.

Question: How do I removed old client indexes

Answer: You can removed the indexes manually with rm -r. The indexes should also get removed automaticly by networker when all tapes with savesets are recycled or the savesets have expired.

Question: How do I ad pre and post processing on NT?

Answer: You must add savepnpc into the backup command field of the client. This will create a <GroupName>.res file in the directory /nsr/res. You can edit this file to fulfill your needs. Below is a <GroupName>.res file we are using:

type: savepnpc;
precmd: "c:\\win32app\\nsr\\res\pre.bat";
pstcmd: "c:\\win32app\\nsr\\res\pst.bat";

This file is used on a NT-server, notice \\ in the command line. In the pre/pst.bat files the following is necessary to run the commands succesfully: All variables which come with the 'set' command.
cmd /c "net stop <service name>"
echo + > <filename>
del <filename>

The last 2 lines are needed to give the bat file a 'exit 0' status. If NO 'exit 0' status comes from the batfile then NO backup will be made. This is due to the fact that some NT-services finish succesfully with a 'exit 1' status and NetWorker checks for 'exit 0'.

Question: How do I implement Towers of Hanoi?

Answer: Set up a schedule as follows...

    Monday:  Level 5
    Tuesday:  Level 4
    Wednesday:  Level 7
    Thursday:  Level 6
    Friday:  Level 1 or monthly Level 0

Most of my clients get a full backup once a month and a partial backup on each of the other days. The day that each client gets its full backup on is distributed (manually) over the month so that we get roughly even backup times.

Question: How do I clone a backup?

Answer:First, make sure you have two devices configured correctly, and that you have a Clone Pool setting. Networker installs a Default Clone Pool that you can use. Next, label a tape with the Clone Pool and run the following command...

nsrclone -v volume001 volume002 ...

Question: What does save: RAP error, ClientPaks for UNIX/NSR enabler does not exist in the system (severity 5, number 12) mean

Answer: With the upgrade to version 6.0 of networker, it finally started caring about ClientPak licenses. You will need to enter an enabler code (with nsrcap probably) for a ClientPak module. This is an add-on module, much like an autochanger module (JSM-8) or an extra client module (5 Clients). This should only be the case if your clients are on different platforms then your server. Like in my case, I have a Solaris server and two FreeBSD clients.
