My Mac broke down. But I do have a backup on my iPhone. How can I restore it?
If you are using the standalone version MobileFamilyTree Pro your databases are completely saved on your mobile device. Recovering your databases is no problem at all. Just sync your database with MacFamilyTree on your Mac and your databases are available on your Mac again.
If you are using the companion application MobileFamilyTree 2 or a prior version it is much more difficult to recover your "lost" databases.
Unfortunately, we can't suggest any solution here. The data being transferred to the iPhone is a small subset of the data you can save in MacFamilyTree. Syncing data with MobileFamilyTree lets you edit that data on the go but it is not intended as a backup. You can't restore your database from MobileFamilyTree.
The only way to ensure you won't loose your data is backing up that data with backup solutions like Time Machine or CarbonCopyCloner to an external drive. If you upload your family tree to MacFamilyTree.com and activate the option for GEDCOM upload, you will be able to import that data into MacFamilyTree again, albeit without the media files.
