backup important files

Few months ago when I was having computer hard drive failure, it took almost a month before i could get my notebook back. A month without my toy seems like an eternity to me.. well, almost! lol* One thing i regret is when the technician told me that he didn't got the chance to saved any of the files and documents i had on the system. What a pity! So from now on, I am using online backup services to retrieved files just in case same thing happens.
