I've got a Raspberry Pi running Openelec with a 3TB Verbatim USB drive. The drive came pre-partitioned as a 2TB and a (roughly) 800GB partition. The 2TB partition is formatted as NTFS and has all my media on there. I plugged the drive into my MacBook Pro (Mountain Lion) and configured Time Machine on the 800GB partition and ran the first backup successfully.

I then put the USB back in the Pi and mounted the 800GB partition as /var/TimeMachine which is shared as "TimeMachine" on the network. I can connect to this partition from my MBP and TimeMachine recognises the drive, mentions that "The identity of the backup disk “TIMEMACHINE” has changed since the previous backup." I select "Use this disk" and it initiates backup but then returns the following error:

"Time Machine couldn’t complete the backup to “TIMEMACHINE”. The backup disk image “/Volumes/TimeMachine/John's MacBook Pro.sparsebundle” could not be created (error 13)."

Anybody got an idea how to get this working? Or am I barking up the wrong tree here?

Is the Pi's HFS+ support good enough for this?
What is the format of the 800GB partition?
 
As of OS X Lion, Apple disabled support for Time Machine backups onto network drives that use SMB. AFP networks shares are fine. Snow Leopard will work SMB, Lion and Mountain Lion won't. There are workarounds but I'm not comfortable backing up to a workaround. I think backups should be done on something a bit more reliable. To test this a while back, I installed Mountain Lion on a regular PC using the TonyMac method, setup an AFP share and Time Machine backups worked fine. I'm now using an external hard drive for Time Machine backups. I would love to buy a Time Capsule but its stupid expensive. The NAS I have supports AFP in theory. I'll try playing with it this weekend to see if Time Machine works.
 
Mmm - then OP should start here
netatalk + hfs would be critical for RPi to work. But I do agree - a more reliable system would be better.
 
I used that method to get Time Machine to work on an Ubuntu server but I didn't trust it. Just had that feeling that it was not going to work just when I needed it.

You and I are the same. I had this nervous, twisted feeling in my stomach. It all happens via USB for now (and the foreseeable future).
 
Simply because I am. Any reason I shouldn't be? The other option was exFAT but, from what I could gather, it's much of a muchness.
