Back Up and Restore Elasticsearch Indices

Elasticsearch's high availability and redundancy make it a stable and reliable platform for storing massive amounts of data. However, to protect yourself from human error and natural disaster, you should always back up your Elasticsearch data. Where you store your Elasticsearch data backups is entirely up to you. In this hands-on lab, we will use the local filesystem to demonstrate how to: * Create snapshot repos * Back up specific indexes * Restore data from a snapshot

Challenge

Create and configure the snapshot directory.
Using the Secure Shell (SSH), log in to the node-1 node as cloud_user via the public IP address.

Become the elastic user with:
```
sudo su - elastic
```
Create the directory where snapshots will be stored with:
```
mkdir /home/elastic/snapshot
```
Add the following line to /home/elastic/elasticsearch/config/elasticsearch.yml:
```
path.repo: "/home/elastic/snapshots"
```
Restart the elasticsearch node with:
```
pkill -F /home/elastic/elasticsearch/pid
/home/elastic/elasticsearch/bin/elasticsearch -d -p pid
```

Challenge

Create the "test_repo" repository.

Use the Kibana console tool to execute the following:

PUT _snapshot/test_repo
{
  "type": "fs",
  "settings": {
    "location": "/home/elastic/snapshots"
  }
}

Challenge

Back up the "bank" index.

Use the Kibana console tool to execute the following:

PUT _snapshot/test_repo/bank_1?wait_for_completion=true
{
  "indices": "bank", 
  "include_global_state": false
}

Challenge

Restore the "bank" index as "bank_restored".

Use the Kibana console tool to execute the following:

POST _snapshot/test_repo/bank_1/_restore
{
  "indices": "bank",
  "rename_pattern": "(.+)",
  "rename_replacement": "$1_restored"
}
