Add Option to Enable TimeMachine Support on Shares

[LordPhoenix-ZA]

Finding it hard to enable Time Machine support without messing with samba.conf. Would be nice if Casa had an option to enable a share for TimeMachine support. So Mac users can do backups.

Understand your needs, but I'm sure we don't have time to do this anytime soon. If there are other greats in the community who can work with you on this issue, it can be merged into casaos @LordPhoenix-ZA

This is the one feature I'd really like to see

Workaround 1:

(The main magic is the 'vfs objects' line)

Workaround 2:

This is a very heavy handed solution, but people have resorted to using Open Media Vault for creating the Time Machine shares

This comes down to several sub tasks

• Provide User interface to enable TimeMachine
• Update global config
• Update volume config (e.g. fruit:time machine = yes)
• Creating a user? (e.g. valid users = timemachine)
• Restart smb?

I've started a branch here with the easy parts changed. As I'm not a go developer, I'll give an open invitation for anyone to jump in on this.

This will require more testing as enabling time machine support is complicated and easily breaks older macs as shown in the open media vault community

• enabling time machine breaks all other smb shares
• xattr settings on smb shares
• recomended xattr settings

For reference, here is the jinga template that OMV uses

Additionally it is recommended that when enabling time machine on 1 share, you set vfs objects = on every other share

Here is a quick workaround to enable TimeMachine support:

1. Install vfs modules with command: apt install samba-vfs-modules
   Wihout this, TimeMachine configuration breaks all other smb shares.
2. Uncomment line vfs objects = fruit streams_xattr in /etc/samba/smb.conf
3. Add the following lines to enable TimeMachine support to the end of smb.conf file.
   Feel free to change valid users to one from valid SAMBA user as well share name and backup max size.

[TimeMachine_Backup]
 path=/shares/Backup
 valid users = pi
 guest ok = no
 read only = no
 browseable = no
 public = no
 fruit:time machine = yes
 fruit:time machine max size = 300G
 fruit:metadata = stream
 durable handles = yes
 kernel oplocks = no
 kernel share modes = no
 posix locking = no
 ea support = yes
 inherit acls = yes

Would also love to see the support for this.

@iravit the valid users section. You have Pi. Which I assume would mean your SSH user, not your Casa OS user correct?

Of course I can create a new user, but should it be at the terminal level or in Casa? For example I would like to give my wife access to back up her computer with Time Machine but not have full access to the Pi.

Thanks!

Update from @iravit original

sudo nano /etc/samba/smb.conf

Uncomment line vfs objects = fruit streams_xattr in /etc/samba/smb.conf

Add:

[TimeMachine_Backup]
path=/media/devmon/EXT
valid users = devmon
guest ok = no
read only = no
browseable = no
public = no
fruit:time machine = yes
fruit:time machine max size = 1000G
fruit:metadata = stream
durable handles = yes
kernel oplocks = no
kernel share modes = no
posix locking = no
ea support = yes
inherit acls = yes

sudo smbpasswd -a devmon
=> set password to: devmon

EXT = exFat 1TB disk, named/casa auto-mounted as EXT

Using user devmon allows you to not have to fight with permissions from the USB auto-mount... also seems vfs is included in the latest casaos/samba, no need to install it.
