ChronoSync review

ChronoSync is the most complete sync tool here for Mac owners. Econ Technologies sells it as an all-in-one app for incremental and bi-directional file and folder syncs, incremental and bootable backups, and compatibility with iCloud and other cloud services. The classic use the vendor describes is matching an office desktop with a travel laptop before you leave and again when you return. You can schedule tasks at almost any interval, drill into the folder tree to control exactly what will happen, and preview the results before committing. Targets include external drives, remote Macs running ChronoAgent, SFTP servers, and cloud services such as iCloud, Dropbox, Amazon and Backblaze. The license is $49.99, there is a free trial with no credit card, and the vendor says it has updated the app over 70 times since 2002 without charging an upgrade fee. It needs macOS 10.14 or newer, so it is no help on Windows or Linux, and it takes longer to learn than Dropbox.
