Answer 1

Your query looks good. But do you have the appropriate permissions to create a repo at "/mount/backups/my_backup". Try your curl command as a sudo user. It's worth a shot !

Reason why I think its a permissions issue is because of the following in your error log. nested: BlobStoreException[Failed to create directory at [/mount/backups/my_backup]]; ","status":500}

Answer 2

Got the same error, and I had to make sure the same path was writable on ALL nodes (as the same user). I mounted the directory directly on one of the nodes, and used nfs to mount on the other ones. To troubleshoot perms, edit /etc/passwd and change the login shell for elasticsearch from /sbin/nolgin to /bin/bash and then run 'su - elasticsearch'. Then try writing a file to the directory. You have to do that on all the nodes.

1. First create a backup folder(Generally that folder create user home folder)

   mkdir ~/backup
   

2. Give permission for that folder

   chmod 777 ~/backup
   

3. Create a repository (Repository is represent you path)

   curl -XPUT http://xx.xx.xx.xx:9200/_snapshot/es_snap -d 
   '{"type":"fs","settings":{"location":"home/user/backup"
   ,"compress":true}}'
   

4. Snapshot

   curl -XPUT "http://xx.xx.xx.xx:9200/_snapshot/en_snap/snapshot_1" -d 
   '{"indices":["index1","index2","index3"],"ignore_unavailable":true,
   "include_global_state": false,}'
   

5. Restore

   curl -XPOST "http://xx.xx.xx.xx:9200/_snapshot/es_snap/snapshot_1/_restore" -d 
   '{"indices":["index1","index2"],"ignore_unavailable":true,
   "include_global_state": false}'
