Re: back up questions
I concur. NAS is a good starting point.
In order to have a real backup solution, though, you will want to have at least two copies-- one off-site, so that if anything catastrophic happened (say, a fire in your home/apartment; or even sillier, your NAS drive crapped out), you'll still have another copy of your backup files.
Off-site could mean a few burned discs or a portable drive in a safe-deposit box or at work, or 'cloud' storage, where you upload data to the internet.
Of course, storing data in the cloud requires internet access, which might not always be available (which is why I prefer to have physical copies in the form of burned DVDs and duplicated hard drives.
