How to organize a backup in Elasticsearch?

Question

elasticsearch

Off. The documentation says that you need to create a repository for the snapshot, etc.
But when I want to create a repository I get this response from the elasticsaerch server.

curl -XPUT ' 192.168.100.150:9200/_snapshot/elastic_demo_backup ' -d '{"type": "fs", "settings": {"location": "/home/elastic_backup/", "compress": true } } '
{"error":"RepositoryException[[elastic_demo_backup] failed to create repository]; nested: CreationException[Guice creation errors:\n\n1) Error injecting constructor, org.elasticsearch.repositories.RepositoryException: [elastic_demo_backup] location [/home/ elastic_backup/] doesn't match any of the locations specified by path.repo because this setting is empty\n at org.elasticsearch.repositories.fs.FsRepository.(Unknown Source)\n while locating org.elasticsearch.repositories.fs.
