Rebuilding Movable Type blog completed just now. One simple stupidity (too stupid to mention), not myriad mistakes made this blog out of cyberspace last quarter. All the entries that I posted and maintained over the past ten plus years totally disappeared due to irrevocable backup copies.
Physical failure can be constant risk in server operation and maintenance. Backup as well as recovery plan is a basic and perfect measure in most of cases. However, the backup must be done properly. This is the lesson that I learnt.
