1. OS part- filesystem, probably reiserfs (fast)- tweaked boot for high performance- tweaked kernel, highmem, disk access and stuff
2. database part- various maintanace scripts (for now using them for backups and vacuuming)- jump to pg8 :(- autovacuum???- implementing a logging facility to RAM, flushing logs in background to disk?????
3. backup part- backup is done by shell scripts and cron (change? not likely)- backups on other machines (over scp for other linux hosts, samba for 'secure' Windows2000???, eventually a pro backup app although i don't think it is necessary, maybe for whole system recovery)
4. spying, early warning, notification part.- monitoring disk space, backup files dimensions, excerpts from certain log files, system status and stats (cpu usage, ram etc), monitoring pg sessions because the internal pg monitor sucks :(, we need a good policy on killing iddle sessions and runaway processes.
