Question

Which software is best for disk mirroring?

Community Answer

Handy Backup is a great software. The free version will do most basic tasks, and you can upgrade to the pay version for more advanced tasks.

Warnings

A mirrored hard drive is only as useful as the last time you backed it up; any new data will not be included. Many software mirroring programs include a feature that automatically backs up new data on a weekly or monthly basis (known as “Set and Forget” scheduling). When selecting a software package, this is an important feature to consider.
