Any suggestions of software to keep 2 external USB drives in synch?
I have two 2TB USB drives connected to a computer. One drive is storing around 1TB of data so far and I would like the second drive to mirror the other drive (ghetto USB raid).
Optimally I would like to be able to always just deal with the primary drive and the secondary drive would just automatically mirror the contents of whatever is on the primary usb drive. This synchronization could happen as changes occur or nightly. It doesn't really matter. Because of the amount of data it will probably need to keep track of changes because copying 1TB+ of data from USB to USB is slow.
Any suggestions on how I could set this up? Each drive should be useable without the other (exact mirror) but I will be using one as a primary that should be the 'master' drive.

And if you want to maintain perfect file times, use a Robocopy pass using EasyRobocopy afterwards. Turn off data copy and Robo will just align the directory file times. – Jon – 2017-02-23T04:05:12.240
