Preventive Maintenance Plan for Windows and Unix servers

I need to create a preventive maintenance plan for a client with a break fix contract and require all possible input for a Microsoft and Unix environment.

By "break-fix contract", I take it you mean the customer breaks the system and you have to fix it - And that they are regularly calling about problems that could be avoided with some preventative maintenance. Such tasks and any alerts should be automated as much as possible - Why have a computer and do the work yourself?

Backup, to enable recover from file corruption or deletion, or a hardware failure. Work out a backup schedule that covers all eventualities and train the users to perform the backups. Give them checklists to record task completion & timings. Test the backups regularly.

Monitor CPU, disk, memory and network utilisation. Ensure you have a "profile" for normal loads (e.g. daytime interactive use, nighttime batch jobs) and raise alerts if usage varies from the profiles.  Collect performance data with `sar` or similar

Check that the usual processes are running.
Check for errors and security issues in log files - http://sourceforge.net/projects/swatch/
Monitor log file growth and rotate/clear down as appropriate
Check network connectivity.

Collect system configuration info - in case anything changes: "cfg2html" works on a variety of systems

Patching for security and reliability

For a single system, scripts or "Monit" ( http://mmonit.com/monit/ ) might be appropriate. For a network, consider setting up a Nagios monitoring server

Other tasks depend on what the system is used for. Review the calls the customer has put in, to see what could have been prevented
