So...I see a lot of examples using things like this from [Snapshot and Restore][1]:
PUT /_snapshot/my_backup
{
  "type": "fs",
  "settings": {
        ... repository specific settings ...
  }
}
And my question is...how are people putting things like this in?  They just telneting to port 9200 on localhost and putting them in manually?  Or creating a file on the server in the html dir and accessing it?  Would love to know..I need to make a snapshot before I do my upgrade.  Thank you.
