Dear Expert,
the Network departement need to create a zone for master server and ask to change the IP address for the master.
Can i change the IP address for the master server?
is there a risk like the backup we have already available will corrupt?
Are there any procedures to change the IP else change on hosts files on all media and client?
i have Win 2008 R2, NBU 7.1.0.3.

I did this very recently, and followed this procedure:
Shutdown all media servers
Stop NBU services on Master
Change IP address on Master
Update DNS to reflect new IP address with Master Server name
Re-boot Master Server
Restart all media servers
Doing the above removes the need for clearing any cache etc.
All worked out fine.

After changing IP I wold wait 10-20 minutes before starting Netbackup so IP changes are replicated to all DNS servers. If really long TTL (server time to live) are defined more time may be required.

Agree with all of the above - just one thing that may catch you out ....
Hosts files - lots of people use them, especially with clients across firewalls so keep an eye on any failures that ocurr after the change
But changing the IP address will have no effect and will no corrupt your NetBackup installation - just look for backup failures afterwards, check hosts file and do a bpclntcmd -clear_host_cache on clients that fail (or an ipconfig flushdns)
Hope this helps
