Online backups are created once a month. When a new backup file is generated, you will get an email with the link to retrieve a backup of a specific tree in a specific site.
Links to the backups are also available on your family site under the “Family Tree” tab in the “Backup” section:
1. Move your mouse cursor over the 'Family tree' tab and click on 'More...':
2. Select 'Backup':
There you will find a list of all backups that have been created with a description of the backup file, its size and instructions for downloading the backup and using it to restore the tree.
How to restore a family tree originally created online (WEB tree):
The backup file will be a GEDCOM file with a .GED extension. You can download it to your computer. All photos associated with the tree are linked in the GEDCOM file and will be retrieved when you restore your tree to your MyHeritage family website or to the Family Tree Builder software.
To import the file to your family site, log in to the site, move your mouse over the ‘Family tree’ tab, and click on ‘Import GEDCOM’.
If your family site already contains another version of that tree, then the tree will be duplicated in the family site. Importing the GEDCOM will not replace any existing tree in a family site. The process will also duplicate photos if the photos are still located on the family site.
