Backing Up

[ahuckphin]

I own a 3 TB Western Digital My Book and a 4 TB Western Digital My Passport drive. 

 

The My Passport is my primary drive.

 

It may have inferior performance but it is more convenient not requiring supplementary wall power. 

 

Is there a program that can backup my data from the 4 TB drive into the 3 TB drive. Maybe a cloning software?

 

I am aware I cannot cramp 4 TB of data into just 3 TB but my 4 TB drive has less than 3 TB of data.

There is lots of backups software like the one made in windows, veeam, and use robocopy to copy the files.

I'm using FreeFileSync and can recommend that.
