To backup your genealogy files onto BackupMyTree, go to BackupMyTree
When I first used BackupMyTree, it took quite a while (days) to sync all the files and gedcoms I had on my computer, even though it says on the website it only takes minutes. It uses minimal resources always working in the background to update the latest version of your genealogy program file, and I haven't noticed any slowdown when it is running. There is no limit to the files it will backup and I was quite surprised to see how many files it found on my computer. However, each file backed up is limited to 1 gigabyte in size.
When I go to BackupMyTree, the website always opens up in Google Chrome, which is not my default browser, but I do have it installed on my computer. I'm not sure, but the program might require a Google Chrome download.
Hint: If you use FamilyTreeMaker, do a monthly backup (file - backup) within the program and be sure to tick the box called "include media files" . This will save your data plus all photos and images to a .ftmb backup file which BackupmyTree will backup for you as long as your file is not larger than 1 gigabyte. Great way to get photos and Ancestry.com record images backed up along with your genealogy database file.
