What is the difference between rb bucket and db bucket?

Hi Splunker;

What is the difference between rb_* and db_* under splunk_cold and splunk_hot directory storage? you can see the example below.

rb_1564000917_1563984040_7538_0B51C6C4-28F7-4348-A8F4-51FD8D156178
db_1562576411_1562565181_7654_B0AF5CBE-9B45-46D7-B374-E398083AFE9E

And can I remove the rb bucket or not?

Regards

Buckets starting with "rb_" are replicated buckets - copies of buckets from other indexers in the cluster.
Do not delete them. If you do, Splunk will just re-create them.
Don't bother backing them up, either. You'll just waste backup time and storage. Splunk will re-create the rb buckets after the backup is restored.
