Backing up the Log Server Environment

We will be going from a single node to a 2-node cluster. Currently, we have Netbackup backing up the current server in addition to the backup you provide. Do we need to back up the second server with netbackup in addition to what the log server is backing up nightly? Is the data different on each node?
Newbee to the log server.

What are you already backing up? I assume you have attached NLS to an NFS repository or similar and you're doing full log backups.
In addition to full log backups, there are configuration backups generated nightly. Configuration backups are found here:
/store/backups/nagioslogserver/
If the above is true, my backup recommendations are as follows:
1. Have NLS cluster running with 2/3+ instances. This enables the cluster to be highly available and redundant.
2. Backup all logs to a different server. (typically via NFS) - be sure to back up your configuration backups as well.
3. Backup all of those logs _again_ to an off-site server.
4. If there's ever a catastrophe, you can use your config backup to restore all of your settings to a new NLS cluster, and you can use your log backup to restore all of the data.
There's no need to backup the entire server - the log backup + configuration backup is what I recommend.
Thanks!
