ElasticSearch is a powerful open-source search and analytics engine designed for horizontal scalability, reliability, and real-time search capabilities. It is widely used for log and event data analysis, full-text search, and operational intelligence. ElasticSearch allows users to store, search, and analyze large volumes of data quickly and in near real-time.
When working with ElasticSearch, you might encounter the InvalidSnapshotNameException. This error typically occurs when attempting to create a snapshot with a name that does not comply with ElasticSearch's naming conventions.
When this exception is thrown, you will see an error message similar to the following:
{
"error": "InvalidSnapshotNameException",
"reason": "[snapshot_name] Invalid snapshot name [snapshot_name], must be lowercase and not contain special characters"
}
The InvalidSnapshotNameException is triggered when the snapshot name provided does not adhere to the required format. ElasticSearch imposes certain restrictions on snapshot names to ensure consistency and prevent conflicts. The name must be lowercase and cannot contain special characters such as spaces, slashes, or backslashes.
To resolve this issue, you need to ensure that your snapshot names comply with ElasticSearch's naming conventions. Follow these steps:
Ensure that your snapshot name:
If your snapshot name does not meet the criteria, rename it. For example, if your snapshot name is My_Snapshot_2023, change it to my_snapshot_2023.
Once you have a valid name, attempt to create the snapshot again using the following command:
PUT /_snapshot/my_backup/my_snapshot_2023
