How often does the search head send the knowledge bundles to the indexers?

[sarnagar]

My indexer has /opt/splunk/var/run/searchpeers.
How often do searchpeers get updated?
I also have an old backup searchpeers.bak which is occupying space.
So, can I remove searchpeers.bak?

Hi,
Haven't deleted that info, but I think it would
get replicated again...since bundle won't get overwritten when
Splunk is upgraded.

you can reduce the size of the bundle by means of the
[replicationWhitelist] or [replicationBlacklist] stanza in
distsearch.conf . See "Modify the knowledge bundle" in the deployment manual.
