Weird Time Machine errors on Leopard Server

When I open the main GIU of the Leopard Server there's always an error pop up on the screen from Time Machine. This error states that 'a' backup malfunctioned, but all backups seem ok.

I looked through the logs and found this: (note that most backups finish ok, just some with the error below)
4/24/09 9:38:15 AM /System/Library/CoreServices/backupd[64124] Starting standard backup

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....

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)
(ALL SPACES MUST BE TABS!!)
config_version 1.2
snapshot_root /backups/
cmd_cp /bin/cp
cmd_rm /bin/rm
cmd_rsync /usr/bin/rsync
cmd_ssh /usr/bin/ssh
cmd_logger /usr/bin/logger
cmd_du /usr/bin/du
cmd_rsnapshot_diff /usr/bin/rsnapshot-diff
interval hourly 6
interval daily 7
interval weekly 4
interval monthly 6

loglevel 3
logfile /var/log/rsnapshot.log
lockfile /var/run/rsnapshot.pid
rsync_short_args -a
rsync_long_args --delete --numeric-ids --relative --delete-excluded
exclude /backups
exclude /dev
exclude /media
exclude /proc
exclude /tmp
exclude /mnt
exclude /sys
exclude /proc
exclude /var/cache/zoneminder/events
backup / localhost/

Then add this to /etc/crontab:
0 */4 * * * root /usr/bin/rsnapshot hourly
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
