If you want to restore multiple issues, do that using the REST API. ? Edited

Any examples?

"Restore" implies that you are getting issues out of a backup.

There is no way to do a "restore" of individual issues.  The REST API calls will actually be creating new issues based on the data in the backup.  See https://developer.atlassian.com/server/jira/platform/jira-rest-api-examples/ for some examples

Thanks for answer,

but if it possible to restore bulk with api? 

I cant found anything like that

No, you have to do it one issue at a time.  But iterating over a list is trivial in most languages that you might choose to do the REST API calls with.
