Backups functioning…

From now on the backups of the server are fully functional.

Hardware failures

To guard against hardware failures, I use mirroring on the server now
with two disks and have third disk for backup. Every week or so one
disk is removed from the array and replaced by the free disk. This way,
I have a complete server backup.

Accidents/software failures

To guard against software failures and ‘accidents’ (accidentally
removing files e.g.) I have implemented backups of the  server of
parts of the directory structure. I use the ‘dar’ program for that.
Every month, a full backup is made, and then every day of the month, an
incremental backup is made (if no full backup was made). The backups
are stored on the hard disk of the server. Of course, the mambo
installation, configuration, and mysql databases for mambo are backed
up. Mysql is backed up by first creating a database dump using
mysqldump and then backing up the snapshot using the regular procedure.

Laptop broken

My (private) laptop  is broken. It appears that laptops do not function very
well after a  certain amount of beer has been poured over the
keyboard. Screwing open the laptop, just as you do when adding memory,
and letting it dry  for a night is my last hope before II send it for  repair.

Experiments with magnolia

Today, I experimented a bit with another open source content management
system (Magnolia).  Magnolia is base don J2EE so that would give
me a bit more control than Mambo perhaps because I know J2EE but not
PHP on which Mambo is based.

Modem problems/all services unreachable

Because I downgraded my ADSL  subscription from comfort to standard, I had to
reconfigure the modem. What I did not realize was that this
reconfiguration somehow erased all the port-address translations in the
modem.  As a result of this problem, all services on the site were
unreachable from Friday evening 4th March to Sunday evening 6th March.

The server now regularly reconfigures the modem with the precise PAT settings so that this problem cannot occur anymore.

Improved backups

Just ordered another hard disk sled in addition to the two I already
have so that I can use a total of three disks to store my data on and
easily swap disks while still using mirrorring onthe server. Basic
idea is to store the third disk in another (geographic) location and to
exchange one of the disks every now and then. This way, I allways have
a (fairly) recent backup of all my data.

Also scheduled regular verification of the RAID array using cron. The
highpoint RAID scheduling functions are not working it appears.
