Received this email this morning – I haven't requested anything from Zoho.
"Per your request, we have uploaded your complete Zoho CRM data and attachments to your Zoho CRM account. To download these files, please log in to your Zoho CRM account and click on the following links:"
This is a very common question. Within your paid Zoho Subscription you are allowed a free monthly "Data Backup". In reality, Zoho backup your data far more frequently than once a month. What this really is, is a monthly export of your data. Some customers like to have a physical copy of their data outside of Zoho. I always set this up for customers and then you have the option to download it once a month, quarter or never. By default they are sent to the Super User of the CRM account.
