Sync Folders Pro is perfect for backups to external storage devices including:
USB, memory cards, disks on remote computers within your network, folders on Cloud services (Dropbox, etc.) With each re-backup, the app finds and copies only new files and new file versions, thereby reducing backup time and extending the life of your storage devices.

Update to Pro+ (website version) and create a bootable clone of your hard drive and you can use it if your main drive is crashed.

The app can synchronize multiple pairs of folders at the same time "on the fly" using our "REAL TIME SYNC" technology, on a schedule or manually. The Sync Folders Pro also provides robust tools to filter files and folders so that you sync exactly what you want.
