BackUpMyTree, a free online backup service for your genealogy files, launched today.

After you install BackupMyTree software, created by the team behind Pearl Street Software and its Family Tree Legends genealogy program (purchased by MyHeritage in 2007), the software will automatically find family tree files on your computer. It creates a remote, off-site backup you can restore if necessary, and maintains multiple previous versions of your files.

You also can opt to manually upload files through your browser, rather than install the BackupMyTree software.

The service is free. “In the future, we will offer a Pro version of our service for a small yearly fee,” says creator Cliff Shaw. “This version will offer more features, but we will always keep the free version the way it is.”

In addition, there’s no limit on the file size you can store—yet. “If we impose some sort of limit in the future, it will be a very high limit, and we will let all our users know,” Shaw says.

Note that photos and other media included in your tree aren’t yet backed up. According to the site’s FAQ: “We plan on adding this in the near future. Family Tree Maker [genealogy software] often stores photos inside the file, so these photos are backed up as a function of being included in the file.”

BackupMyTree software works on Windows systems. The service supports the genealogy applications Family Tree Maker, Personal Ancestral File, RootsMagic 4, Legacy Family Tree, Family Tree Legends, Family Tree Builder, and GenoPro.
