The word back-up does leaved a mark on me last week when my sub-domain went wacko! Everything went haywire (including me!), from the scripts down to my databases (mysql). And worst, it coincides with the transfer of my files to another server by my hosting company.
Its a good thing that I manage to download a backup on my pc two weeks before it happen or else I would literally went back from scratch. Just a reminder for all of you out there who have important data on your blogs/site, if you value your work and want to survive those system crashes it would be best to religiously do a back-up (not a back flip lol). You’ll never know of some problems our servers might encounter like Denial of Service (DOS) Attacks, virus infection, being hacked or some malfunction on their hardwares. Even big internet companies like Yahoo or Google are not spared from this kind of catasthrophe. At least if you have your own backup you’ll feel much more relax and have peace of mind.
