Ulysses for Mac and iPad include an automatic backup feature that is turned on by default. On the Mac, your data is automatically backed up hourly (keeping the last 12 hours), daily (keeping the last 7 days) and weekly (keeping the last 6 months). Backed up files are stored on your computer. iPad backups are less frequent because of the devices space restrictions.
You can browse your backup files using the Browse Backups button in the Preferences panel or File > Browse Backups… To restore specific content, use the Browse window to drag and drop the needed content into your current library.
It is also possible to “lock” a backup so it won’t be automatically erased when it hits the standard backup schedule.
Currently there is no plan to offer a cloud backup option.
