Ask HN: Your recommendations for Windows PC backup software solutions? 12 years ago
I would check out NovaBACKUP for Windows PC backup software. It supports Windows 7, will allow you to backup to USB or to a local NAS device (including Synology) and offers cloud backup options. It also offers full, incremental and differential backups. Hope this helps: http://www.novastor.com/en/software/windows-backup
