Time Machine no longer sees shared drive

I have a Firewire drive connected to my iMac and sharing enabled. 2 MacBook Airs then connect wirelessly to the same network and backup to the drive.

It has worked perfectly for the last couple of years with Lion and Mountain Lion.

Yesterday I upgraded to Mavericks and now neither laptop can see the shared drive in Time Machine, although the drive displays quite happily in Finder.

I have disabled and re-enabled sharing. Booted and re-plugged the drive in and still when I go to Time Machine preferences and select drive, nothing is listed.

Any ideas?

I’ve spent 2 days on this and its VERY hit and miss to say the least!

My research leads me ot this….

Still can’t get it to work properly though!

But it’s supposed to swap back automatically for Time Machine but it doesn’t seem to happen!

I give in. I’ll buy a NAS drive instead.

That may be the case but all my shared time machine drives no longer work. The macs just don't see them anymore unless I connect to the server using AFP. Then after sleep or a reboot it fails again.

It just doesn't fall back from SMB to AFP.

Never ever had time machine sharing issues in ML now after 3 days of constant troubleshooting I still can't get it to work reliably on mavericks.

Thanks it does and it works fine until my machine wakes again from sleep and then one again the backup fails and I have to go to finder, click on the backup disk and then go to Time Machine and start the backup and then it backs up fine again.
