Samba is an open sourced implementation of SMB that it used by WD and others. WD introduced TM over SMB on other products, see for example My Cloud OS since last September, so it seems that WS masters the implementation.įinally, Samba 4.8 released on 13 March 2018 is said to support TM (over SMB).
To my understanding, it specifies extensions to the SMB protocol to ensure reliable backups. You don’t need to change any Time Machine settings to back up APFS-formatted disks.Īny Time Machine share points must be shared over SMB instead of AFP.Īctually, TM over SMB is supported since Sierra (10.12) and Apple published a specification on 13 September 2016 (see: ). WD must be using some sort of hacking to use AFP for Time Machine because Apple said that, when using APFS (which is mandatory with SSD under High Sierra), TM is only supported over SMB Shares (See. To my surprise, I found that Time Machine (abridged TM afterwards) backups are still mounted through Apple Filing Protocol, which has been superseded by SMB2 as the default protocol for sharing files starting with OS X Mavericks (10.9). I have recently bought a My Cloud Home Duo after having received confirmation from WD that it supported macOS High Sierra.
