SyncThing

SyncThing is a continuous file synchronization program. It synchronizes files between two or more computers in real time, safely protected from prying eyes. Your data is your data alone and you deserve to choose where it is stored, whether it is shared with some third party, and how it’s transmitted over the internet.

It basically keep folders in synchronization between hosts. hosts can be computers and also mobile devices.

Gentoo has an ebuild for SyncThing, so just emerge it:

emerge syncthing

For SyncThing to be useful you need to run it as the users group, and you should also ensure SyncThing data and logs are stored on your raid arrays. Edit the /etc/conf.d/syncthing configuration file:

synchting

SYNCTHING_USER="syncthing"
SYNCTHING_GROUP="users"

# Configuration directory
SYNCTHING_HOMEDIR="/data/syncthing/.config/syncthing"

# Log file location
SYNCTHING_LOGFILE="/data/syncthing/syncthing.log"

And create the /data/syncthing folder that will contain default shared folders and logs:

mkdir /data/syncthing

Add it to default runlevel and start it:

rc-update add syncthing default
/etc/init.t/syncthing start
