Backup
Do them regularly and have a schedule for them because if you are a lone person the last thing you’ll want is to loose those old photo’s or the downloaded music, now if your a company IT guy you are dealing with other peoples data not just the companies survival or not if it goes wrong. Now I just suffered a server go down because I changed something that shouldn’t have done it but it did and I was lucky my email is buffered off site for a few weeks in case just a thing occurs and it is just Exchange for the most part that seems affected and I can get in and save our data. I learnt there’s no such thing as never all over again and gone out to buy a Tandberg RDX QuikStor 160GB Removable Disk Cartridge and Enclosure to backup those files before I start reinstalling Windows and Exchange. The Tandberg is a good combination of space that has a chance to grow with the server and my data, current drives are up to 500GB, and speed because it is after all a hard disk and not some tape so it can be used to get your files off no mater what system was running on the server because it will in theory mount on anything. I’ll let you know when I get it but even the included software sounds pretty decent.
