For use cases with frequent updates, such as backup software like Commvault, NetBackup, Veeam et al, restoring an Elasticsearch index from backup is not suitable. After restoring a specific point-in-time of the Elasticsearch index, the backup client software may not be able to read the data beyond that time. To address this, a “Refresh Search Index” is required, which . This synchronizes the Elasticsearch Index with the current state of data in the storage cluster. This refresh process can take almost the same amount of time as creating a new search feed, which is why recovery of Elasticsearch from backup is less beneficial for these use cases.

• Elasticsearch cluster running.

• Shared file system accessible by all Elasticsearch nodes.

• Access to the cluster via curl or a similar HTTP client.

• (Optional) Elasticsearch Curator for automating snapshots.
