I say No. The more the better.
!. Get and use an External Hard Drive, the bigger the better.
2. Use one of the “Cloud” or Online options Mozy, SugarSync, Dropbox,Time Machine(Mac only)
3. For files you can’t afford to lose get a Memory Stick and use it to store any files that meet the criteria.
4. Same ideas for any web sites you have. Do a daily Database backup, do a Full backup which you both download and keep one in a file as a part of your Blog. Do a content backup.
Sure this is a belt and suspenders approach, but at least you’ll never lose your pants in real life nor your hard work on sites, computers, documents, etc.
