Macos – How to backup a Mac to a NAS (Samba-connected Windows share)


I'd like to find an (semi-)automated way to backup my whole MacBook Pro system and data to a network attached storage. The external storage is a Windows share I can access using Samba.

I can't use Time Machine, because it asks for a Time Capsule device – or is there a way to use Time Machine without a Time Capsule?


Best Answer

You can 'force' Time Machine to backup to other mounted network shares. In Terminal, run the following:

defaults write TMShowUnsupportedNetworkVolumes 1

This should then allow you to backup to your SMB, AFP and NFS network shares. If they do not initially show up in Time Machine, mount them and then re-check.
