Couldn't remember so I tested it with a new share. You'll need to first mount the share in macOS before it's visible in Time Machine.

Good catch! Yes, that is indeed possible. I'll change my original post.

@DjossSame problem as @rbot. The log /config/Online Backup/00000000-0000-0000-0000-000000000000/logs/log_WebAccess.log contains the following error when you try to logon: [ERROR]: [ CBB ] [ 19 ] Failed to read shadow entry for user: <username>

@rctneil Yes, <ShareName> is a placeholder for your own shares. You'll have to explicitly specify each and everyone of them. For example: [appdata] path = /mnt/user/appdata veto files = /._*/.DS_Store/ delete veto files = yes The Time Machine backup is successfully finished so it seems to be working

Ok, I have it working. I think. The backup is running now. I used different guides from these forums and ReddIt and also the official samba and vfs_fruit man pages. Situation: Client: macOS Monterey 12.1 Server: Unraid 6.9.2 I have a Backups share as a staging area for servers and clients to put files before they're back-upped to the cloud. This share I made available to Apple's Time Machine with the following settings: First, the global SMB settings in Settings > SMB: Enhanced macOS interoperability: Yes Enable NetBIOS: No Second, the SMB Extras settings in Settings > SMB (stored in /boot/config/smb-extra.conf if you prefer the command line): [Global] min protocol = SMB2 ea support = yes vfs objects = catia fruit streams_xattr fruit:aapl = yes fruit:nfs_aces = no fruit:zero_file_id = yes fruit:metadata = stream fruit:encoding = native fruit:model = MacSamba veto files = /._*/.DS_Store/ delete veto files = yes [Backups] path = /mnt/user/Backups fruit:time machine = yes fruit:time machine max size = 3 T In my case I used a maximum size of 3TB for the Time Machine backups. A nice extra with this configuration: a faster browsing experience of SMB shares in macOS (at least in Finder). Note of caution: if you use the Unassigned Devices plugin, the above configuration needs to be included before '#unassigned_devices_start'. Finally, for the Backups share, the specific SMB settings: The Time Machine volume size limit (3TB in MB) here is probably useless as it is overridden by the SMB Extras settings. Hope it helps some of you.
