What is inside
One spreadsheet per kind of record, with plain column names such as "Customer name", "Invoice no." and "Assigned (email)". It opens in Excel or Google Sheets.
Records linked by their reference (an invoice number, a customer reference, a staff email), so the files make sense on their own.
Your custom fields, one column each, under the names you gave them.
What is never inside
Passwords and two-step codes
API keys, and the connection details of your WhatsApp, email, ad and payment accounts
Bank details of affiliates, and staff ID or passport numbers
Images and files: they stay in your Lead10 storage
How it is protected
Only admins with permission to manage backups can make, download or restore one.
Downloading asks for your account password, and your two-step code if you use one. Every backup, download and restore is recorded in the activity log.
You can lock the file with its own password. Keep that password safe: without it, nobody can open the file.
When automatic backups are switched on or sent somewhere new, every admin who manages backups is told.
Because the files are ordinary spreadsheets, treat a downloaded backup like any other confidential business file.
