Elasticsearch – InvalidSnapshotNameException

 InvalidSnapshotNameException

If you are getting the InvalidSnapshotNameException exception in elasticsearch while creating the snapshot for the indices.

{
   "error":"InvalidSnapshotNameException[[snapshot_name_goes_here:Logstash] Invalid snapshot name [Logstash], 
   must be lowercase]",
   "status":400
}

From the exception itself, It is clearly shown that, Elasticsearch accepts only lower-case name for snapshot, This is applicable for both Snapshot and Indices as well.

If you get exception in smaller case as well, please check the snapshot name you have given, The same exception you will get if you give wrong snapshot name.

curl -XGET 'http://localhost:9200/_snapshot/_all?pretty=true'

                                  [ or ]

# From the browser or rest client 

http://<<IP_of-Elasticsearch-Host>>:9200/_snapshot/_all?pretty=true
