> Key: SOLR-15842
> URL: https://issues.apache.org/jira/browse/SOLR-15842
> Project: Solr
> Issue Type: Bug

> When [backing up|#backup]] a collection either for the *S3 Repository* or the
> {*}LocalFileSystemRepository{*}, if I provide the *async* parameter and then
> check the status of the backup with the [REQUESTSTATUS|#requeststatus]]
> endpoint, even if the backup finishes successfully, the *indexSizeMB*
> parameter is always 0.
> If I do a *sync* backup and wait until it finishes, then the *indexSizeMB*
> parameter has the right value.
> Here are some examples of the responses for each case:
> h3. S3 Backup (Sync)
