I've been running local Time Machine backups to an external FireWire drive since I got my MacBook a few months ago. But now that my wife picked up a MacBook as well, I'd like to move to a solution that works without USB/FireWire.
I run two servers at home, an unRAID server as my file storage server, and an Ubuntu 12.04 server as my front end (mostly for things like Sabnzbd, SickBeard, ect...). I found this post the other day and followed it to the letter:
The difference for me though, was I mounted my unRAID "TimeMachine" share as a local drive on Ubuntu (/mnt/TimeMachine) by modifying my fstab file. So far, so good.
I'm able to select the new networked TimeMachine drive on our Mac's and choose it as the hard drive. But when I try to run a backup, I get the following error:
"Time Machine couldn't complete the back to "homeserver". The Backup disk image "/Volumes/Time Machine on Ubuntu/Kris' MacBook Pro.sparesbundle" could not be created (error 22)."
I did a bit of searching and found that permissions seem off in my /Volumes directory on the mac. For example, I have a "/Volumes/Time Capsule" drive mounted which is my external drive connected via FireWire. It has kris:staff as the owners, and 775 as the permissions.
However, the "/Volumes/TM on Ubuntu" that I gets mounted when I try to use the network share for Time Machine backups has root:wheel as the owners, and 700 as the permissions.
Why is that? Do I need to configure something differently on my Ubuntu Server to get the mac to mount this with proper permissions?
