Generally, coal and charcoal exhibit distinct differences in terms of their formation, properties, and uses. Coal is a fossil fuel formed from decaying plant and animal matter under high temperature and pressure, taking millions of years to form. Coal is mined like other minerals and is a non-renewable natural resource.

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.
