![put](https://raw.githubusercontent.com/minio/minio/master/docs/bucket/versioning/versioning_PUT_versionEnabled.png)

This protects against accidental overwrites or deletes of objects, allows previous versions to be retrieved.

When you DELETE an object, all versions remain in the bucket and MinIO adds a delete marker, as shown below:

            attributes.put("snippetsPath", "snippets");
            // Make sure the 'raw' location of the samples is available in all AsciidoctorTasks to access files with expected outputs in the 'tests' folder for inclusion in READMEs
            attributes.put("samplesPath", extension.getUserManual().getStagingRoot().dir("raw/samples").get().getAsFile());
            task.attributes(attributes);
        });
