["Pavel Pereslegin (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-15450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17481846#comment-17481846 ] 

Pavel Pereslegin commented on IGNITE-15450:
-------------------------------------------

The final solution is to add a "wait" flag to wait for the entire operation to complete.

*Create*
{noformat}
  Create cluster snapshot:
    control.(sh|bat) --snapshot create snapshot_name [--wait]

    Parameters:
      snapshot_name  - Snapshot name.
      wait           - Wait for the entire operation to complete. Otherwise, the operation will be performed in the background, and the command will immediately return control.
{noformat}

*Restore*
{noformat}
  Restore snapshot:
    control.(sh|bat) --snapshot restore snapshot_name [--wait] [--groups group1,...groupN]

    Parameters:
      snapshot_name     - Snapshot name.
      wait              - Wait for the entire operation to complete. Otherwise, the operation will be performed in the background, and the command will immediately return control.
      group1,...groupN  - Cache group names.

> The process of restoring a snapshot fails if at least one of the restored caches already exists. 
>  However, when starting this operation via control.sh, the command returns a successful startup status, which can be confusing for users.
> We can improve this behavior by adding a separate check for existing caches when starting the restore operation and displaying a user-friendly error message.
> An *alternative* option is to start a snapshot restore operation synchronously.
