This article is about how MAC and raspberry pie achieve file sharing and TM backup. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Use netatalk to let Linux share files with Mac OS X

Build Time Machine backup server for Mac

The Mac OS X system comes with an easy-to-use backup software, Time Machine, which can back up incremental backups every hour (that is, only documents with changes), so if you use a MacBook Pro/Air laptop and need to deal with a lot of documents, then using Time Machine to back up over a wireless network is a good choice. Unfortunately, using Time Machine requires an external hard drive or buying an Apple Time Capsule device, and the following way is to install netatalk software so that a regular Linux raspberry pie can share files with Mac OS X and act as a backup server for Time Machine.

1. Install netatalk for raspberry pie

Netatalk is a free and open source implementation of the AppleTalk communication protocol, through which Linux or BSD systems can act as Mac file servers (AppleShare File Server, network protocols are AFP), AppleTalk routing, print servers, and so on.

# install netatalk using the following command

Y

2. Set up a shared folder

Edit a file

Sudo nano / etc/netatalk/AppleVolumes.default

Each line here represents a shared folder, and the current user's $HOME folder is shared by default. If you don't want to do so, find the "~" line and comment it out, adding the following line:

/ home/pi/nas "CohoStudio_NAS"

This means sharing the / home/pi/nas folder with the name "CohoStudio_NAS".

3. Set up the Time Machine backup folder

Similar to the previous step, just add the parameter "options:tm" after the sharing settings, such as (create a time_capsule under the nas folder):

/ home/pi/nas/time_capsule "Time_Capsule" options:tm

4. Install and configure Avahi

Avahi is an open source implementation of the Apple's Zeroconf protocol that implements Bonjour-like functions that allow you to automatically discover your Linux computer in the Mac system.

Sudo apt-get install avahi-daemon (optional to support automatic discovery of computers on the network)

Create a file

Sudo nano / etc/avahi/services/afpd.service

Write the following (Port:548): (this file already exists in Archlinux and does not need to be created)

% h_afpovertcp._tcp548_device-info._tcp0model=Xserve

5. Start netatalk and avahi

$sudo service netatalk restart$ sudo service avahi-daemon restart

The default 2345 is on, so the following two commands are not necessary.

Pi@cohostudio ~ $sudo chkconfig-- add netatalkinsserv: warning: script 'K01aria2' missing LSB tags and overridesinsserv: warning: script' aria2' missing LSB tags and overridesinsserv: warning: script 'mathkernel' missing LSB tags and overridesnetatalk 0:off 1:off 2:on 3:on 4:on 5:on 6:offpi@cohostudio ~ $sudo chkconfig-- add avahi-daemoninsserv: warning: script' K01aria2' missing LSB tags and overridesinsserv: warning: script 'aria2' missing LSB tags and overridesinsserv: warning: script 'mathkernel' missing LSB tags and overridesavahi-daemon 0:off 1:off 2:on 3:on 4:on 5:on 6:offpi@raspberrypi ~ / nas $sudo service netatalk restartRestarting Netatalk Daemons (this will take a while) Stopping Netatalk Daemons: afpd cnid_metad papd timelord atalkd...Starting Netatalk services (this will take a while): cnid_metad afpd.done.pi@raspberrypi ~ / nas $sudo service avahi-daemon restart [ok] Restarting Avahi mDNS/DNS-SD Daemon: avahi-daemon.

MAC connects to the AFP service on LINUX

Enter the user name pi and password of the linux system to log in.

6. Settings on Mac OSX system

Right-click "Finder"-> "Connect to the server …" -> "server address". After logging in with the account and password in the Linux system, you should see the "CohoStudio_NAS" and "Time_Capsule" folders.

Afp://xxxx.jios.org # AFS server address

Then open a terminal in Mac (located in applications-> Utilities-> Terminal), and execute this command so that Time Machine can use the network disk as the backup destination:

Defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

Open system preferences-> Time Machine-> Open-> Select disk and select the Time Machine folder.

Now that all the settings are complete, let's test it.

7. Backup the MAC system to the raspberry pie

Click the Time Machine icon on the menu bar, and then click "backup now". If there is no problem, you should start backing up files (generally speaking, you can only back up user files, that is, you can exclude all system files). The first backup takes a long time, so it's best to turn on the alternating current and set the energy saver to never go to sleep.
