This will take a while, especially if you set a large file size. Make certain that the Format is set to Mac OS Extended (Journaled).As a word of warning, the size you choose will be the size of the disk space that will be immediately created on the remote share. If you want to be able to at the very least backup the entire contents of a full hard drive, select a size at least equal to your Macintosh HD drive size. We now need to create an 'image' file that will, in essence, pretend to be an APFS filesystem for your Mac for backup.

You should also see that share in Finder in your 'Shared' section and see the 'Eject' icon next to it since it is now mounted. Make sure to save those credentials to your keychain for the OS to automatically use those credentials for connecting to the share for future access.

If you've correctly set everything up, you'll be prompted to enter a registered user and password. For example, if you have a Windows PC named 'Server' and a network shared folder on the Windows PC named 'share,' you'd be able to test for connectivity by doing the following:Įnter smb://Server/Share where 'server' is the name of the Windows PC and 'share' is the name of the shared folder. I won't go into detail on how to create a shared folder on a Windows PC, but before you begin, you'll need to have a shared folder created and accessible to your Mac that you want to run Time Machine on. It's optimized for solid-state drives (SSDs) and other all-flash storage devices, but it also works on mechanical and hybrid drives. The issue that makes Time Machine more complicated in terms of options for backup locations is that it requires the use of the Apple File System (APFS), which first launched with macOS High Sierra.
