samba fun

Short post.

I wanted to repurpose an old external hard drive into a NAS and do time machine backups on it as well. Here’s the smb.conf I used – some special stuff needs to be done to make it work with time machine. Mostly just adding fruit:time machine = yes and the accompanying parameters.

One important thing to note is that your external hard drive cannot be formatted as any FAT since it doesn’t support extended attributes which SAMBA needs to make time machine work. I used btrfs.

[global]
	workgroup = WORKGROUP
	passdb backend = tdbsam
	usershare allow guests = No
	min protocol = SMB2
	ea support = yes
	vfs objects = fruit streams_xattr
	fruit:metadata = stream
	fruit:model = MacSamba
	fruit:posix_rename = yes
	fruit:veto_appledouble = no
	fruit:nfs_aces = no
	fruit:wipe_intentionally_left_blank_rfork = yes
	fruit:delete_empty_adfiles = yes

[nas]
	comment = samba on suse
	valid users = ihasdapie
	path = /PATH/TO/DRIVE/nas
	inherit acls = Yes
	read only = No
	browsable = yes
	writeable = yes
	create mask = 0660
	directory mask = 0770
	browseable = yes

[timemachine]
	comment = Time Machine
	vfs objects = catia fruit streams_xattr
	fruit:time machine = yes
	fruit:time machine max size = 1.0T
	path = /PATH/TO/DRIVE/timemachine
	browseable = yes
	writeable = yes
	case sensitive = true
	default case = lower

Additionally, there are some caveats with the filesystem used on the external hard drive. NTFS and BTRFS and ext4, etc support xattr well, but exFAT doesn’t (or FAT32, etc). So remove streams_xattr from the samba conf for that share if it is a FAT-formatted drive

Right now I’m trying to set up immich on my server to replace google photos. But backblaze has free unlimited backup, but only for mac or windows. So what I did was set up an external drive

1

 sudo mount -t cifs //ihasdapiexmac/disk0 ~/Volumes/disk0 -o username=familyfileshare,dir_mode=0777,file_mode=0777

Not sure why i can’t create files without dir_mode, file_mode not set to 777

Then I set up backblaze to back up that mounted drive :)
