I can add few more:
  1- Whenever possible, I try to make my services run under separate user
that's not root.

  2- MRTG and Syslog are my essential monitoring tools specially if I
manage to get memory and    CPU utilization monitored. In addition to that
I used ActiveXperts (windows) for links availability it send you SMS when
ping to one of your nodes fail. I think Nagios can do the same for linux
platforms but I have never used it before.

 3- Cron along with shell scripts are simple way to automate back-ups, I
just need to make sure proper security is in place.

 4- I also have the habit of preparing all the new configuration in text
files along with the roll-back configuration before applying any changes to
the network node. It helps minimize the errors and down time.

5- terminal servers are must to have specially for remote location, I just
need to make sure that they are connected through separate link for obvious
reasons :).
