RE: [nv-l] a question about backup

[Gareth Holl <gholl@us.ibm.com>]

You should check the contents of the "OV.back...." directory to see if all of your customizations were saved as not all of the directories within /usr/OV are included in a "OV.back...." style backup.

Stephen probably has the best approach for moving NetView to a new box. Just remember that NetView migration does not necessarily include user directories and files. It does not simply copy the entire /usr/OV directory structure and restore it. For example, the migration does not need to copy the contents of the /usr/OV/bin directory as new binaries are being layed down (hence an upgrade), so you might find that either your "OV.back..." directory doesn't contain the scripts you say you stored in /usr/OV/bin, or if they were included then they will be ignored during a migration - you would have to copy them manually.

You will have to perform some form of installation/migration on the new box. I doubt you can simply copy the /usr/OV directory and restore that on a different box which has never had a formal installation performed (and expect it all to work) as there are files placed elsewhere (/etc, /var ??) and other system files updated, like /etc/services. There are probably other gotchas that I haven't mentioned

I don't know what would be considered best practise  - hopefully somebody else can share their experiences.

Hi Gareth.
 
What I need is to replace my Sun server. And I have a lot's of custom config stuff, custom scripts in /usr/OV/bin, oid_to_whatever,..a lot's of ARF add-ons. LRFs mibExpr.conf....and a lot more.
I think if I make OV.back.v7r1 and then use cp -r, that will do it. Is this what NetView does during migration, or something else?
Also, I was thinking to TAR C the whole thing and making up one big OV.tar. 
Basically what I need is the best way of backing up the whole Netview and restoring it on different box. of course with the same IP, SNMP Community...
What is the best way to do this, and what are the best practices?
 
Regards
 
Dejan Mijailovic

This kind of backup is mainly used when performing a migration. The update/migration process looks for the existance of this directory and migrated the databases and conf files and other contents. You could manually go through it and copy parts back in but this would probably be tedious and potentially lead to mistakes. 

If your goal was to backup the NetView databases, simply tar up the /usr/OV/databases/openview directory and restore using pax (don't restore using tar). Or use the "Hot Backup" feature introduced into v7.1 - refer to the 7.1 Release Notes for description and steps to restore.

re: Tivoli Neview 7.1, Solaris 7

Does someone know, after generating backup files/directories "OV.back.v7r1",
how to restore the files back to /usr/OV?
Do I just use "cp -r" after stopping the NetNiew programs or there is a
Netview script to do it?

Thanks
