Apple Time Machine on Server running Gentoo Linux
This guide is about how to add Apple Time Machine to a Server running Gentoo Linux. Since Apple's backup tool only supports thier own filesystem
HFS+, we start with installing it and preparing the disk to be able to create the Time Capsule on it later.
emerge -avq diskdev_cmds mkfs.hfsplus -v Backup /dev/md2 mkdir /mnt/disks/backup # optional: adding a mount point to your fstab echo "/dev/md2 /mnt/disks/backup hfsplus noatime 0 1" >> /etc/fstab
Futher we need to install two services -
avahi-daemon. Netatalk provides Apple's network filesystem protokoll, which is needed since using Time Machine over network requires
afs. The Avahi Daemon is used to make Netatalk available in the network.
# !!! NOTE make sure your use flags contains avahi echo "net-fs/netatalk avahi pgp samba ssl utils" >> /etc/portage/package.use echo "net-fs/netatalk ~amd64" >> /etc/portage/package.keywords emerge -avq netatalk # optional add both service to the autostart rc-update add avahi-daemon default rc-update add netatalk default
The next step is to configure netatalk that OS X could access the network drive by editing
/etc/afs.conf as follows. Make sure the user(s) specified under
valid user exists on the server. If not, create it. A client will need it to access the
afs network drive.
[Global] ; Global server settings ; uam list = uams_dhx.so,uams_dhx2.so,uams_dhx2_passwd.so uam list = uams_dhx.so,uams_dhx2.so save password = no [default_for_all_vol] file perm = 0664 directory perm = 0774 cnid scheme = dbd valid users = phgamper ; [Homes] ; basedir regex = /xxxx ; TMAFPVoume could be replaced by a name of your choice [TMAFPVolume] time machine = yes path = /mnt/disks/backup/timecapsule vol size limit = 1000000
Once we finished, we create the Time Capsule for the specified user(s). As mentioned above a client has to authenticate when connecting to the network file system. Thus the user has to own or at least has read, wirte and execution rights to the folder, where the capsule will finally be stored.
mkdir /mnt/disks/backup/timecapsule chown phgamper /mnt/disks/backup/timecapsule
Finally we are finish with configuring the server and could go on starting netatalk and avahi-daemon.
/etc/init.d/avahi-daemon start /etc/init.d/netatalk start
Now the server is ready and should appear in the Time Machine's system configuration. If not, the following fix on your client should work.
