Spinbackup for Business backs up your Google Calendar automatically every day. The very first backup starts the next day after you sign up. However, at some exact moment you may need to backup your data manually. With Spinbackup, you can do it.
If you have a Spinbackup account, you can rest assured that accidentally lost or maliciously deleted Google Calendar events will be easily recovered to a specific date. Even the whole Google Calendar account can be restored with several clicks.
In the Google Calendar backup interface you can manually backup and restore events, migrate events to a different user, download them to a local device, view your events, and use the advanced search bar to search for specific events.
