Not so much online video, more good practice

I use different computers for video editing, distribution etc and for everything else. I back up my editing PC almost on a daily basis -- I'm about to buy my THIRD terrabyte external hard drive. But to my shame, I forgot about the other machine. There are lots of housekeeping chores I do with it on a regular basis. I defrag. I run AdAware checks. I use CCleaner to cleanse the internet temp files and keep the Registry in good order. But somehow, I always put off backing up the main drive and exporting the Outlook and Explorer files. This weekend was salutory. I'd done all of the usual tasks on Friday, run out of time and thought "I'll do the back-up tomorrow" (having just downloaded loads of important, educational files). Saturday morning came and I tried to boot up the PC --- and it wouldn't!!! It wouldn't even boot up in "safe" mode. I tried just about everything. Nothing worked. So it was down to our local, excellent PC service depot (DATA in Portobello) on Monday. Thankfully, they found that some of the files in Windows had become corrupted; they were very easy to sort. Here I am, back online with the formerly sick PC. The documents files have been backup up. My Outlook files have as well, as have bookmarks. So for good practice, either employ a company do to it automatically for you or schedule a backup into your diary every week. You know it makes sense.
