John Smith reviewedChronoSyncProfessional backup and synchronization for macOS
 RecommendedPros: 

User friendly

Has all the features I need for computer backup, file archiving, and synchronizing hard drives.

Free updates for life.

Cons: 

Some of the more advanced features can be a little tricky to learn. But don't worry, the documentation and customer support is great.

Just buy it. It's a great product with excellent customer service and support. The one-time $50 price tag is a total steal for what you get. I never ever have to worry about losing any of my data, ever, thanks to Chronosync.

It says I've used this product for 1 year because that's the longest duration you can choose, but I've been using it for many years at this point, and I love it.
