Configuring TimeMachine

defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

System Restore using TimeMachine: From OSX boot dvd you will need to drop to a shell and manually mount the share in the /Volumes directory…

mount -t afp afp://username:password@hostname/TimeMachine /Volumes/TimeMachine

---

FYI: There is no direct way to quota or limit share sizes on AFS shares, you must either configure your share on a separate partition, create a loopback filesystem for the share or manually create a sparcebundle file with a limit in DiskUtility (named “<host>_<mac>.spacebundle”) and configure TimeMachine to backup to it.

dd if=/dev/zero of=/var/TimeMachine.img bs=10M count=10240
mkfs -t ext2 -b 2048 -v Timemachine.img
echo "/var/TimeMachine.img /mnt/TimeMachine auto loop,auto,rw   0       0" >> /etc/fstab
mkdir /mnt/TimeMachine
mount /mnt/TimeMachine
