I’m typically pretty good at backing up my computers. One of my most prized piece of data is the GEDCOM file that contains a decade of genealogy research — more than 18,000 linked relatives.
I often upload a copy of my genealogy database once a quarter to sites like www.ancestry.com, jasonpearce.tribalpages.com, and www.rootsweb.com about once a quarter. This gives me an offsite backup. The crutch is I have to remember to do it.
A new and free service from www.backupmytree.com does it for you automatically. It works with several genealogy programs and silently uploads your family tree as you make changes. They even keep the past 25 versions, offering you some version control. They plan on offering a professional version with extra features to pay for their service.
