What is the best sync software, free or paid, for Synchronize 2-way ? Meaning it keeps Drive A and Drive B with the same files. So if you delete something from Drive A it is deleted from Drive B or the opposite.
Here is a topic/forum where a similar question was raised. You'll find some good suggestions here: https://www.wilderssecurity.com/threads/simple-backup-for-parents.375612/#post-2485869 There is a huge list of suggestions here: http://www.techsupportalert.com/content/security-list-view-nodes.htm And, a good set of recommendations with some discussion about each one here: http://www.techsupportalert.com/best-free-folder-synchronization-utility.htm
I have been using Syncfolders ( http://www.syncfolders.elementfx.com/ ) for at least 2 years since moving away from synctoy. Highly configurable and the syncs are fast. Professional looking GUI and has many features, including Copy, Backup, Sync: Source to Destination including USB, external storage, partitions, scans ie simulations without actual syncing, errors detail, total MB moved, copied, as well as number of files deleted, and much more.
I am very surprised how well this software works. Thanks to you, I found my go to Syncing software, I appreciate it
