Hello everyone. I have been trying to get this to work for a while now and im getting no where. When I had Mavericks I would have it backup to a .sparsebundle on my home server running windows xp. Now with yosemite no matter what I do I cant get it to work. I have made the sparsebundle with my local name and MAC address, then moved it to the backup folder on my windows xp server, I have tried mounting it, not mounting it, with SMB on and AFP on, with both off, with one on one off, I have tried to mount it straight into TM by doing "sudo tmutil setdestination /Volumes/Backups/"the name I gave it".sparsebundle and I get this error "Incompatible file system type: smbfs (error 45)", I tried without the .sparsebundle, nothing seems to work. Any ideas? Its a bit frustrating considering that I got it working on Mavericks on my first try with no problems at all. Thank you. Ernie.
