To do a full backup of our QNAP server I built a CentOS 6.3 machine with plenty of SATA storage. This CentOS server has Rsnapshot installed so that it will not only backup the QNAP, but will also provide incremental backups for accidentally erased or overwritten files on the QNAP.
Webmin
The CentOS server has Webmin installed for easy configuration. Access to webmin is trough port 10000.
QNAP shares work around
For backup up the QNAP the internal Rsync server is enabled and a username and password is set. To prevent the necessity of having to add all shares of the QNAP manually, and updating them for each new future share, we added a special share. This trick is simple, create a new share and manually add the path. This path should simply be "/", this way this share will hold all shares on the QNAP, including the Time Machine shares and others.
Rsnapshot Configuration
Next up was configuring the rsnapshot.conf on the CentOS machine. Contents of config file: (used cat /etc/rsnapshot.conf | grep -v -e ^# to get this output btw)
(ALL SPACES MUST BE TABS!!)

backup rsync://rsnapshot@192.168.0.2/all/ jupiter/ +rsync_long_args=--password-file=/etc/rsnapshot.password --exclude=.timemachine/ --exclude=Jupiter/
Anacron scheduling
To schedule all backups automatically the following was added to the /etc/crontab file:
0 8,12,16,20 * * * root /usr/bin/rsnapshot hourly
50 23 * * * root /usr/bin/rsnapshot daily
30 23 1,8,15,22 * * root /usr/bin/rsnapshot weekly
10 23 1 * * root /usr/bin/rsnapshot monthly

Linux Server Rebuild
Building a new Ubuntu 10.04 LTS server. The old Ubuntu server needed a replacement of both hardware and software.
Hardware Setup:
A new 19" C2D DFI-ACP machine is used with four SATA drives:
- 250 GB System
- 500 GB Network Share
- 500 GB Backups
- 1 TB Zoneminder Events
Installation:
Ubuntu was installed from a CD without LVM on /dev/sda (250GB) Options chose where:
- Web Server
- File Server
- MySQL
- PostGreSQL
First network settings:
auto eth0
iface eth0 inet static
address 192.168.0.5
netmask 255.255.255.0
gateway 192.168.0.3
sudo ifdown -a
sudo ifup -a
The rest is mainly taken from this guide on www.zoneminder.com

Updated NFS backup script
We had a problem that when the NFS where all the backups on our network go is offline, a huge TAR is made in the root of the Linux file server. Not good!
After some searching and playing with SH (beware! different from BASH) scripts, I came up with this solution:
#!/bin/sh
/usr/bin/MountSaturnBackup
sleep 2
DT=`stat -f -L -c %T /mnt/backup`
if [ "$DT" = "nfs" ]; then
tar cpf /mnt/backup/FullBackup.tar --same-owner --exclude=/network/backups/Jupiter --exclude=/var/cache/zoneminder/events/* --exclude=/proc/* --exclude=/media/* --exclude=/d$
fi
The correct thing to do would be to add an else statement and have the script send me an email. I'll look at that later....

DaviCAL installation
Fed up with waiting for Snow Leopard I decided to set up a calender server on our Linux server. After some searching I found out that Davical would be the best solution, especially since we use thunderbird and would like to use lightning as a calerdar client.
I installed DaviCAL on our Ubuntu 7.10 server, this was not very easy! All in all I can't even rember how I exactly did it. My plan is do to the same on a second server and document this step by step.
Most important thing for me is that is all works! There are some disadvantages, but none to big.
Some things to watch out for:
- In the permissions file of PostgreSQL (pg_hba.conf), make sure to post the access control rule at the top of the configuration document!
- The username in the caldav access URL is casesensitive!
- Use this as URL: http://
/ /caldav.php/ /home/
Since DaviCAL uses PostgreSQL instead of MySQL a extra backup routine is important for me. Our MySQL database is backup, so I added an extra backup script:

Adding an Axiz PTZ camera to ZoneMinder
ZoneMinder has the ability to control a PTZ (Pan, Tilt, Zoom) through it's user interface.
I added a Axis 213 PTZ dome camera to our ZoneMinder server using the following settings (After turning on PTZ in the Options->System tab (ZM_OPT_CONTROL), and restarting ZoneMinder):

4/24/09 9:38:27 AM /System/Library/CoreServices/backupd[64124] Backup failed with error: 11
I always thought that Time Machine does not backup mail stuff, but it apparently does backup parts (useless parts) of the IMAP mail store.
The fix I'm trying is to add the /var/imap/users/ dir to the exclude list in the Time Machine preferences screen. See if this helps....
I looked through the logs and found this: (note that most backups finish ok, just some with the error below)

Rebuilding a Zoneminder system after a Crash
The Zoneminder system setup using this link has had a hard disk crash. Not much of the system could be saved. So we chose to rebuild from scratch.
This time we installed a 160GB disk for the system itself and swap, and a seperate 500GB disk for events and backups of the system.
The start of the guide still applies, but we also did the following:
using fdisk created a 6GB for backups and a 482GB partition for events
Formated both as EXT3 and added the following to /etc/fstab:
/dev/sda1 /backups ext3 defaults,errors=remount-ro 0 1
/dev/sda2 /var/cache/zoneminder/events ext3 defaults,errors=remount-ro 0 1
Set correct permissions for the events dir:
sudo chown www-data:www-data /var/cache/zoneminder/events/
Added a time sync script:
sudo nano /etc/cron.daily/timesync
And added:
#!/bin/sh
ntpdate 0.nl.pool.ntp.org
Then:
sudo chmod 755 /etc/cron.daily/timesync
Fix Video permissions:
chmod 4755 /usr/bin/zmfix
Added a MySQL backup script I also use on our main Linux server:
sudo nano /etc/cron.daily/DB_backup
Added:
#!/bin/sh
mv /backups/MySQL_Backup/Daily6.sql /backups/MySQL_Backup/Daily7.sql
mv /backups/MySQL_Backup/Daily5.sql /backups/MySQL_Backup/Daily6.sql
mv /backups/MySQL_Backup/Daily4.sql /backups/MySQL_Backup/Daily5.sql
mv /backups/MySQL_Backup/Daily3.sql /backups/MySQL_Backup/Daily4.sql
mv /backups/MySQL_Backup/Daily2.sql /backups/MySQL_Backup/Daily3.sql
mv /backups/MySQL_Backup/Daily1.sql /backups/MySQL_Backup/Daily2.sql
mv /backups/MySQL_Backup/Daily.sql /backups/MySQL_Backup/Daily1.sql
mysqldump -r /backups/MySQL_Backup/Daily.sql --all-databases
Then ran:
sudo chmod 755 /etc/cron.daily/DB_backup
sudo mkdir /backups/MySQL_Backup
Set up main backup system using Rsnapshot:
sudo apt-get install rsnapshot
sudo nano /etc/rsnapshot.conf (Watch for tabs instead of spaces!!!)
Contents of config file: (used cat /etc/rsnapshot.conf | grep -v -e ^# to get this output btw)

exclude /backups
exclude /dev

exclude /var/cache/zoneminder/events
backup / localhost/
Then add this to /etc/crontab:

50 23 * * * root /usr/bin/rsnapshot daily
40 23 1,8,15,22 * * root /usr/bin/rsnapshot weekly
30 23 1 * * root /usr/bin/rsnapshot monthly
Installed X and setup autologin and auto script run:
sudo apt-get install gdm
sudo apt-get install xorg
On the machine itself (not SSH) ran:
sudo startx
sudo gdmsetup
In gdmsetup I set the user 'zoneminder' as autologin, and set the default session to run the Xclient script.
Create the Xscript:
nano /home/zoneminder/.xsession
And insert:
#!/bin/sh
while ( true )
do
/usr/sbin/xlib_shm-script
sleep 1
done
Then run:
chmod 755 /home/zoneminder/.xsession
Set the correct screen resolution:
sudo apt-get install displayconfig-gtk
sudo displayconfig-gtk
I set this to 800x600, this suits the cameras best
Stop screen blanking by adding this to the /etc/X11/xorg.conf file:
Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
EndSection
Create, setup & install the Xlib_shm Zoneminder raw viewing script:
Check the version numbers! not all Xlib_shm version is compatible with each version of Zonderminder!
sudo wget http://dig.hopto.org/xlib_shm/xlib_shm-0.6.3.tgz
sudo tar xfz xlib_shm-0.6.3.tgz
sudo apt-get install libxv-dev
sudo apt-get install build-essentials
sudo apt-get install libmysqlclient15-dev
sudo nano xlib_shm.c
And changed /usr/local/etc/zm.conf into /etc/zm/zm.conf
sudo make all
Place the binary xlib_shm in /usr/sbin/
sudo chown root.root /usr/sbin/xlib_shm
sudo chmod +s /usr/sbin/xlib_shm
For the actual auto starting of xlib_shm I first created a new shell script:
sudo nano /usr/sbin/xlib_shm-script
And added this:
#!/bin/sh
xlib_shm -m 1 -m 23 -m 11 -m 12 -k 0x07a6d0000 -d 40000
Then:
sudo chmod 755 /usr/sbin/xlib_shm-script
