The native Windows 7 Backup app is experiencing an error when attempting to back up data to a Seagate BlackArmor NAS 220 device configured as RAID 1. The error message 'A backup cannot be done to a remote shared folder which is not hosted on a volume formatted with NTFS' (0x807800B0) is displayed, suggesting that the issue lies with the file system of the remote folder.

This error can be frustrating for users who rely on automatic backups and have experienced no changes to their backup configuration. In this guide, we will explore potential root causes and provide steps to resolve the issue.

🔍 Why This Happens
