Backups over the internet with rsync

From NAS-Central Buffalo - The Linkstation Wiki
Jump to: navigation, search

This set of instructions are intended for running (hopefully secure) backups over the interweb from one location to another with either a telnet-enabled stock linkstation pro/live/tera series, or a debianized LS/TS/kuro.

This guide is related to running NAS to NAS (or really any linux machine) over one lan to another lan through routers, however there are other configurations as well, manipulate as you please. There are ways of setting up windows gui rsync backups as well See Unison File Syncronizer and RsyncOnWindows.


  • Setup dynamic ip updater service
  • Setup rsync or rsync over ssh

Visit and find instructions there :-) (fill in at some point)

Debianized Devices

You can setup 2 NAS's behind routers with dynamic IP's from the ISP with DynDNS or no-ip.

Setup via DynDNS

  • Setup a host at to one of the dynamic sides of your setup with a dns name and IP address

Perl Based - Install ddclient

As a super-user type:
#aptitude install ddclient

This will complete the installation

Configuring ddclient

If you want to reconfigure you seetings use the following command

#dpkg-reconfigure ddclient

You want to make sure it runs as a service and monitors changes in ppp–something that the install wizard doesn’t cover.

Edit the configuration file /etc/ddclient.conf

#vi /etc/ddclient.conf

# Configuration file for ddclient generated by debconf
# /etc/ddclient.conf

If you can’t find the public IP address, then you can have ddclient check your public IP address from the web by editing /etc/ddclient.conf and making it use the web by saying



use=web,, web-skip=’IP Address’

Save and exit the file

Restart ddclient service using the following command

#/etc/init.d/ddclient restart
