With a paid Zoho CRM subscription, you're entitled to two free data backups (also called data downloads) per month. Additional backups beyond that are charged per request.
Go to Setup, then Data Administration, then Data Backup, and set the parameters you need for your export. For details on scheduling your two free monthly backups automatically, see our article on exporting data from Zoho CRM twice a month.
Once the backup completes, the account's Super Admin receives an email with the subject line "Your request to export data," containing links to download the export to your own storage. These links expire 48 hours after the email is sent, so it's worth downloading promptly rather than leaving it for later. The exported data comes in Zoho's own proprietary format.
If you need your data as a series of Excel spreadsheets rather than Zoho's proprietary format, you can request this directly from Zoho support, though this is usually treated as a separate, chargeable request rather than part of the standard backup process. Confirm current pricing and turnaround with Zoho support when you make the request, since terms like this change over time.
