Description
You can easily Backup and Sync Hard Drives on Mac automatically with a software that's been around for a decade.
Chronosync allows you to set two hard drives to be an identical backup of each other and you'll never risk losing your files again.
A great feature of this software is scheduling your backup between hard drives.
This allows you to back them up when you are not using the computer and you can set this up as a daily task for the program.
