My 2 cents,

NetView 7.1 has new function that lets you pause specific daemons to allow
you to make a backup image of the production databases.     After the
backup, the daemons would continue.   This will now allow a "FAST" backup.
You could then send that image to your backup server, restore the database,
run reset_ci and have it ready to start NetView (or have it running as a
hot backup)

The old "backup" NetView process had issues that some people found
unworkable
1. at failover time the backup NetView had to "manage" all the resources
that had been "unmanaged".   This caused many traps within the NetView
system.    This was a performance hit at failover time.
2. any interfaces that had been "unmanaged" in production were all now
"managed" since that information was not able to be saved and restored.
This caused the new system to show a lot of "red" when it really wasn't at
first.
3. you had to administer 2 NetView maps.

NetView 7.1 will let you accomplish a primary/backup NetView system much
easier than the old NetView versions.   There were ways to make it happen
in NetView 5 and 6, but it took a lot of custom scripting which we have
done for some customers.    NetView 7.1 should make that more available to
everyone.   NetView 7.1 should make it simpler to write a script to do the
backup, move files and restore on the backup without impacting the
production server.

Kind regards,
