TreeVault Cloud Service is a feature in Family Tree Maker 2019 that allows users to sync their family tree data with Ancestry.com’s online family tree service. This feature makes it easy for users to keep their tree data up-to-date across multiple devices and share it with other family members. TreeVault Cloud Service is a new service launch with Family Tree Maker Software. MacKiev introduced FTM2019 in September 2019 and has provided free cloud service for one year. TreeVault Cloud service is not a traditional cloud storage system. It is different compared to DropBox, Google Drive, or iCloud. With this storage system, you can download your tree if your computer is crashed or is lost. You do not lose any information when downloading the family tree from TreeVault.
