In addition to the bug fixes, CIFS provides the following enhancements and changes in OES 2018 SP3.
This feature allows client to continue using opened files even after a temporary connection loss. A durable handle is a special file handle (from SMB server perspective) that is preserved in case of client’s temporary connection loss and allows them to continue file operations where it stopped once connectivity is restored.
Apple Time Machine (ATM) is a default application for backing up MAC clients data to local and network volumes. As part of this feature, Apple extensions (of the SMB protocol) are implemented to let ATM backup MAC client's data to the NSS volumes.
Toggling between SMB Versions: By default, the SMB v1 sessions are disabled and SMB v3 option is enabled.
