[Help] Apple dropping support for AFP for Time Machine

[REBELinBLUE]

On the latest version of macOS you get these warnings when backing up to a Time Machine share on a F4-210 running 4.2.44





https://support.apple.com/en-gb/102423? ... s-04282025

If I turn off AFP and connect to the share via SMB it does not show as a suitable target in Time Machine, from what I know it needs to be SMB v3 which smbutil shows it is

Code: Select all

❯ smbutil statshares -a

Disable older versions of SMB (if that's possible on TOS 4 on ARM) & it should become a "suitable target".

[REBELinBLUE]

There is no option to disable older versions of SMB in TOS 4 from what I have found

[IrisLi]

1. Yes, according to the output results, the SMB_VERSION field: SMB_3.1.1 clearly indicates the latest subversion of SMB v3.

2. There is indeed no option to disable SMB1 on the page. However, you can go to Control Panel - File Services - SMB page, and in the advanced options, you can adjust the minimum version to SMB2.

[REBELinBLUE]

There is no such option unfortunately

[REBELinBLUE]

Sorry but that is obviously not true.

If it were to only supports SMB1, it would be absolutely ridiculous as SMB1 was deprecated back in 2013, long before TOS4 was released.

But "smbutil statshares -a" clearly shows that the share is using SMB 3.1.1 and has 1, 2 and 3 enabled

Code: Select all

                              SMB_NEGOTIATE                 SMBV_NEG_SMB1_ENABLED
                              SMB_NEGOTIATE                 SMBV_NEG_SMB2_ENABLED
                              SMB_NEGOTIATE                 SMBV_NEG_SMB3_ENABLED
                              SMB_VERSION                   SMB_3.1.1

[REBELinBLUE]

The problem appears to be that samba has not been compiled with the vfs modules needed, "acl_xattr fruit streams_xattr aio_pthread" and with the appropriate config in the Samba global config

Code: Select all

vfs objects = acl_xattr fruit streams_xattr aio_pthread
fruit:aapl = yes
fruit:model = MacSamba
fruit:posix_rename = yes
fruit:metadata = stream
fruit:nfs_aces = no
recycle:keeptree = no
oplocks = yes
locking = yes

and in the TM share

Code: Select all

fruit:time machine = yes

Of course there is no technical reason Terra-Master can't release an update to TOS 4 to fix this, although they have clearly abandoned it even though they still actively promote and sell the F4-210

[TMzethar]

The promotion and sales of version 210 have already ceased. Due to limitations imposed by the kernel version and some other reasons, it is difficult to make further modifications.

[REBELinBLUE]

The promotion and sales of version 210 have already ceased.

It is still actively sold on your own website



Anyway, it doesn't require a newer kernel version to compile samba with the correct modules
