File-level restore is supported for Micro Focus Open Enterprise Server (Micro Focus OES). Micro Focus NetWare is not supported (Veeam Backup & Replication may fail to detect NSS volumes).
AD-enabled NSS volumes on Open Enterprise Server 2015 are supported. Restore of NSS file/folder permissions is not supported.
