# Clone Index

Clones an existing index.

Indices can only be cloned if they meet the following requirements:

* The target index must not exist.
* The source index must have the same number of primary shards as the target index.
* The node handling the clone process must have sufficient free disk space to accommodate a second copy of the existing index.

## Parameters

| Parameter | Description |
| - | - |
| Index | Name of the source index to clone. |
| Settings | Configuration options for the target index. |
| Target Index | Name of the target index to create. Index names must meet the following criteria: - Lowercase only - Cannot include , /, \*, ?, ", \<, >, \|, ' ' (space character), , (comma), # - Indices prior to 7.0 could contain a colon (:), but that’s been deprecated and won’t be supported in 7.0+ - Cannot start with -, \_, + - Cannot be . or .. - Cannot be longer than 255 bytes (note it is bytes, so multi-byte characters will count towards the 255 limit faster) - Names starting with . are deprecated, except for hidden indices and internal indices managed by plugins. |
