In newer versions of syncthing, this can be found in `~/.config/syncthing/config.xml` as `<disableFsync>false</disableFsync>`. Changing that option to `true` will make syncthing transfer files much faster, on the expense of risking data loss.

Syncthing

Syncthing is a modern file synchronization tool. It synchronizes files between various devices and operating systems. It is a great tool for automatic backup of personal files and smartphones. It has several usefull features:

  • Easy and simple configuration
  • File versioning
  • File ignore patterns

For this setup we will use GlusterFS as the file store backend.

Software

Start by installing syncthing

apt-get install syncthing

Filesystem

Configure your system as a GlusterFS client, so you have the following in your fstab.

/etc/glusterfs/home.vol /srv/home glusterfs defaults,_netdev,rw 0 0

Configuration

For each user that is going to synchronize against this system, create a directory for them in /srv/home and give it the correct ownership.

mkdir /srv/home/kale
chown -R kale:kale /srv/home/kale

For each user add the syncthing service to default runlevel and start it.

systemctl enable syncthing@kale.service
systemctl start syncthing@kale.service

When the syncthing service starts, it creates a set of config files in the users home directory. Edit /home/kale/.config/syncthing/config.xml and look for the section below. Change the address, so the service listens on all interfaces <address>0.0.0.0:8384</address>, instead of just localhost. Notice that when you make this change, your syncthing service is public. Everyone can change it.

   1 <gui enabled="true" tls="false" debugging="false">
   2     <address>127.0.0.1:8384</address>
   3     <apikey>apikey</apikey>
   4     <theme>default</theme>
   5 </gui>

Restart the service for the specific user.

systemctl restart syncthing@kale.service

GUI

It should now be possible to connect to the syncthing GUI on https://syncthing:8384 and configure it.

Credentials

Start by setting up a username, a password and force https. This is done in the settings dialog in the GUI tab. Your installation should now be secure.

Transfer speed

The version of syncthing provided in Debian Buster does not have an option to disable syncthings use of the fsync call.
