Backup Your Gmail to QNAP NAS

Since 2004, Gmail has become the most popular email service in the world. You can use up to 15 GB cloud storage on Google to store all your emails. Though 15 GB might have been sufficient 10 years ago, nowadays it might not be large enough storage capacity for emails. As a result, we need to periodically clean out our inboxes. But is this “simple” process foolproof? According to Backupify’s report “Causes and Solutions for Google Apps Data Loss,”, the #1 reason for data loss within Google Apps is user error – which is 63% of losses reported. We will occasionally delete the wrong files but 0% are lost due to the infrastructure failure are destroyed from disaster.
