Disclaimer: I know absolutely nothing about Mac OSX, and my experiences so far have been pretty frustrating.
So I wanted that a Mac laptop on my home network do its backups on a separate server. Apple normally recommends an Apple router with an Apple hard drive and other closed expensive Apple perceptions of the world. However, most systems allow you to backup to an external server, using their internal backup system.
In short, I
- installed netatalk ("apt-get install netatalk" on Debian, version 2.2.5 as of this writing);
- created a standard unix account for that user, with password;
- created a directory /home/johndoe/TimeMachine for that user (with files owned by that user);
- used the following configurations for netatalk:
/home/johndoe/TimeMachine "TimeMachine" allow:johndoe options:usedots,upriv,tm
- -mimicmodel TimeCapsule6,106 -ipaddr 192.168.1.1 -noddp -uamlist uams_dhx.so,uams_dhx2.so -setuplog "default log_warn /var/log/afpd.log"
NB: in the above, I made netatalk bind 192.168.1.1 specifically, to avoid binding public network interfaces, but presumably you are running a firewall anyway.
ATALK_NAME=myserver [...] CNID_METAD_RUN=yes AFPD_RUN=yes [...] # Legacy stuff. Make sure it is disabled: #ATALKD_RUN=no #PAPD_RUN=no #TIMELORD_RUN=no #A2BOOT_RUN=no
Now, from the Mac laptop, go to the finder and connect the network drive:
- Open the Finder
- Menu: "go" -> "connect to network drive"
- Enter the IP address of the server and connect, it should ask for username and password.
Now go in Time Machine and select your network drive.
If your server is on the same network segment as your client machine, it can use Avahi/Bonjour to detect the server. If not, like me, just connect the drive first from the Finder.
