Best Config for RAID backup

I have 2  2TB MyBook drives that i used Disk Utility to configure as a mirrored RAID, however, whenever I open Disk Utility, it launches a repair cycle on one of the drives that often takes more than a day.

Is there a better way to get redundant back-up for my MacBook Pro?  I also keep lots of archive files on the drives.

I’m considering using the WD Smartware to set 2nd drive to just back-up the first but have not every tried to open this software.

Any thoughts would be appreciated


I’d suggest you to go with Time Machine instead of Smartware…
