Kv Store Backup Failing

Fenilleh — Wed, 07 May 2025 17:08:25 GMT

Hello everybody!
The problem that I have is that when I try to make a Backup of the KVStore on my Search Head, it fails after it is done dumping or while dumping the data.
Splunk tells me to look into the logs but besides some basic info that the backup has failed I cant find any info in splunkd and mongo logs.
From my understanding, it is important that, since I'm using the point_in_time option, I have to make sure no searches are writing into the KV Store when I start the backup. Since Splunk makes a Snapshot of the moment I'm starting the backup, searches that modify the KVStores afterwards shoudln't impact the backup, right?
I made sure no searches have the running status when starting the Backup.
Does anybody have tips or threads that are about this topic?
I thought about stopping the scheduler during the backup, but since there are important searches running I want to look into all the options I have before taking drastic measures.
Thanks for any Tips and Hints in Advance!

Hi @Fenilleh

Is the issue resolved or still you are facing an issue? If issue still persists,please paste the error whatsoever you are getting in splunkd and mongod.

Also, I am attaching one KB article, have a look if that is relevant.

Thanks for Replying!
The issue was forwarded to Splunk Support by me.
I was told that since the Search Head is standalone, the option point_in_time is not needed.
The update was done successfully and the backup was luckily not required to be used.
