The best method for low-bandwith backups (except for the first one) is the use of rsync. So let’s get a rsync daemon running and worry about security later.

Assuming rsync is installed, let’s create the config file used by the daemon in /etc/rsyncd.conf:

vi /etc/rsyncd.conf
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock

ESC
:wq


Basically the daemon runs as root and has a backup module “synology” waiting for connections on port 873. To restrict only specific users to connect to the module I used ‘auth users = root’, put the username/password in /etc/rsyncd.secrets:

vi /etc/rsyncd.secrets
root:12345
ESC
:wq
chmod 640 /etc/rsyncd.secrets
/etc/init.d/rsyncd start

Let see if everything is running correctly:

srv> rsync root@192.168.1.2::
synology NAS rsync backup


Now we can use our rsync client or the network backup feature of the synology nas to replicate to the NSLU2 rsync daemon.

all without encryption and using the root account, not too secure, right?
So, what are our options?

1. Use no encryption
2. Use an SSH tunnel
3. Use SSH and a unprivileged user

assuming the first one is not an option, we can create an SSH tunnel with the following command

ssh -f -L 873:192.168.1.2:873 root@192.168.1.2 sleep 10; rsync -avh /path/to/source root@localhost::synology

This will create a tunnel on port 873 of the localhost to port 873 on the remote host to execute a sleep command. The sleep command causes no stress on the remote host. The tunnel will disconnect itself when the sleep command is done, so we need to execute the rsync command to keep the tunnel active. For more information on auto-closing ssh tunnels, check this website.

This still uses the root account, and also cannot be used with the Network Backup of the Synology. It is possible to use it on the Synology with crontab, but this is not really user-friendly, so we need to create an unprivileged user and connect to the rsync daemon via SSH.

First problem, the rsnc daemon will start with the credentials used by the SSH connection, the allready running daemon will not be used. So we need to have the settings from the running daemon transferred to the home folder of the unprivileged user.

First, create the user, i.e. “rsyncbackup”

useradd -d /home/ -m -c "Backup User" -p rsyncbackup

and login as this user.

Create the same rsyncd.conf as we did for the daemon, but focussed on this user:

log file = /home/rsyncbackup/rsyncd.log
pid file = /home/rsyncbackup/rsyncd.pid
lock file = /home/rsyncbackup/rsync.lock

[synology]
path = /path/to/backuplocation/
comment = NAS rsync backup
read only = no
list = yes
auth users = rsyncbackup
secrets file = /home/rsyncbackup/rsyncd.secrets


Be sure to set te correct permissions for this user to write to the backup destination!

If you start a rsync session using:

rsync -avhe ssh /path/to/source rsyncbackup@192.168.1.2::synology


you will first be prompted for your SSH password and then for the password to access de rsync module “synology”.

Now we have a secure (SSH) connection using an account with no permissions other than write to the backup destination.

If you need to automate this, there are many tutorials on the web explaining how to rsync using SSH public keys, this is a good place to start.

restart ssh daemon:
cd /usr/syno/etc.defaults/rc.d/
./S95sshd.sh restart &

Default repositories:
deb http://ftp.nl.debian.org/debian/ lenny main
deb-src http://ftp.nl.debian.org/debian/ lenny main

Configure the network as static
vi /etc/network/interfaces

remove all and replace with the following:
auto eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.0.0.0
network 10.0.0.0
broadcast 10.255.255.255
gateway 10.0.0.254

Install ssh server:
apt-get install openssh-server

install a better editor:
apt-get install vim-nox

Clear screen at logoff:
vi /etc/profile
add
trap clear 0 at the top

Install vmware tools
Dependencies:
apt-get install linux-headers-`uname -r` psmisc make gcc-4.1
ln -s /usr/bin/gcc-4.1 /usr/bin/gcc

install/upgrade vmware tools
mount /dev/cdrom /media/cdrom
cp /media/cdrom/VMwareTools-3.5.0-158874.tar.gz /tmp/
cd /tmp/
tar zxvf VMwareTools-3.5.0-158874.tar.gz
./vmware-install.pl

SNAPSHOT ! ! !

Find the line

mydestination = $myhostname (this will be the domain you entered in the gui)

For additional domains, just add them to this line, ie:

mydestination = $myhostname mydomain1.com mydomain2.com

Note: Every user will receive mail for all domain names, so johndoe@mydomain1.com, johndoe@mydomain2.com, etc.

I really dislike going through control panel, network connections, etc just to have a static ip address for a simple action which will take me 10 minutes and then changing it back.

Here is how to automate it, I created a batch file which will set a static ip, subnetmask, default gateway and dns followed by a pause command. after you press the any key it will change everything back to dhcp.

@ECHO OFF
ECHO Set static address 10.0.0.10?
pause
netsh interface ip set address "Local Area Connection" static 10.0.0.10 255.0.0.0 10.0.0.254 1
netsh interface ip add dns "Local Area Connection" 10.0.0.1
netsh interface ip add dns "Local Area Connection" 10.0.0.2 index=2
ECHO Set dynamic address?
pause
netsh interface ip set address "Local Area Connection" dhcp
netsh interface ip set dns "Local Area Connection" dhcp

vcbmounter -h virtualcenter.domain.com -u username -p password -a name:nameofthevm -t file -r c:\mnt\nameofthevm -m nbd

To unmount

vcbmounter -h virtualcenter.domain.com -u username -p password -U c:\mnt\nameofthevm

Although ntbackup is unsupported for use with VCB, because it has no pre- and post-scripts, you can however use a batch file to mount de VM, start ntbackup and unmount the vm.

Paste the following in a .bat file and change it to your needs:

@ECHO OFF
SET VCBFW="C:\Program Files\VMware\VMware Consolidated Backup Framework"
%VCBFW%\vcbmounter -h virtualcenter.domain.com -u username -p password -a name:%1 -t file -r c:\mnt\%1 -m nbd
ntbackup backup c:\mnt\%1\letters\c /j "%1 C-disk" /f "c:\ntbackup\%1.bkf" /snap:off /m normal
%VCBFW%\vcbmounter -h virtualcenter.domain.com -u username -p password -U c:\mnt\%1


usage: vcb.bat servername
Use Task Scheduler to schedule the backup using this batch file.

Update:
You can also backup the full VM by changing the following in the batch file:
%VCBFW%\vcbmounter -h virtualcenter.domain.com -u username -p password -a name:%1 -t fullvm -r c:\mnt\%1 -m nbd -M 1 -F 1
and
ntbackup backup c:\mnt\%1 /j "%1 Full backup" /f "c:\ntbackup\%1.bkf" /snap:off /m normal
