1. Create a Snapshot Repository

   First, create a snapshot repository where the snapshots will be stored. This can be a shared file system, Amazon S3, HDFS, etc. For this example, we'll use a shared file system.

   Code Block
   curl -X PUT "http://<es_node_ip>:9200/_snapshot/my_backup" -H 'Content-Type: application/json' -d' { "type": "fs", "settings": { "location": "/mount/backups/my_backup" } }'

   When the target repository is another Swarm cluster, the command to create the snapshot repository would be as follows:

   Code Block
   curl -X PUT "http://<es_node_ip>:9200/_snapshot/my_s3_backup" -H 'Content-Type: application/json' -d' { "type": "s3", "settings": { "bucket": "my-elasticsearch-backup-bucket", "endpoint": "https://datacore-swarm.example.com", "access_key": "your_access_key", "secret_key": "your_secret_key", "protocol": "https" } }'

Ensure that the location path is accessible and writable by all nodes in the cluster.

2. Verify the Repository

   After creating the repository, verify it to ensure it is set up correctly:

   Code Block
   curl -X GET "http://<es_node_ip>:9200/_snapshot/my_backup"

3. Create a Snapshot

   Once the repository is set up and verified, create a snapshot of your index. Replace index_mumbkctcomobs.ipstorage.tatacommunications.com0 with your index name.

   Code Block
   curl -X PUT "http://<es_node_ip>:9200/_snapshot/my_backup/snapshot_$(date +\%Y\%m\%d\%H\%M)" -H 'Content-Type: application/json' -d' { "indices": "index_mumbkctcomobs.ipstorage.tatacommunications.com0", "ignore_unavailable": true, "include_global_state": false }'

4. Automate Snapshot Creation

   To automate the creation of snapshots, you can use cron jobs on Linux or scheduled tasks on Windows.

   Example using a cron job (runs daily at 2 AM):

   Code Block
   0 2 * * * curl -X PUT "http://<es_node_ip>:9200/_snapshot/my_backup/snapshot_$(date +\%Y\%m\%d\%H\%M)" -H 'Content-Type: application/json' -d' { "indices": "index_mumbkctcomobs.ipstorage.tatacommunications.com0", "ignore_unavailable": true, "include_global_state": false }'

5. Monitor Snapshots

   Regularly check the status of your snapshots to ensure they are completing successfully:

   Code Block
   curl -X GET "http://<es_node_ip>:9200/_snapshot/my_backup/_all/_status"

6. Restoring a Snapshot (if needed)

   If you need to restore a snapshot, you can do so with the following command:

   Code Block
   curl -X POST "http://<es_node_ip>:9200/_snapshot/my_backup/snapshot_<snapshot_date>/_restore" -H 'Content-Type: application/json' -d' { "indices": "index_mumbkctcomobs.ipstorage.tatacommunications.com0", "ignore_unavailable": true, "include_global_state": false }'
