HDD Backup Software Recommendations

[Blizzforte]

I need great backup software for my external HDDs. I've heard Hard Disk Sentinel Pro has one but I don't know if it does what I need. Would be nice if it could backup files from one external HDD to another so that I don't need to copy everything twice. And if it can do it once a day, month, etc.

You can use something like robocopy and task scheudle to do this, and its all include din windows, and will sync the files on the drives.

Thanks. But what about all those duplicate files in the subfolders? And will this do a scheduled backup or do I need to type in commands each time?

task scheduler will schedule the task.

 

It won't copy duplicates.

How will it determine what a duplicate is and what isn't? Say the file has the same name but the size is different?
