What we back up:
Modules such as Leads, Accounts, Contacts, Deals, Forecasts, Activities, and so on.
Records linked to these modules.
Attachments
Notes
Users
What we don't back up:
Blue prints
CRM Variables which can have unique set of values and can be widely used as merge fields in Email templates, Mail merge templates, and Inventory templates.
The reason that some of these data types are not backed up is because they are not made available in Zoho's API. As soon as these data types are available through the API we will add them to the backup scope.
