    Can somewhat be used for similar purpose (synchronization, sftp, network share). Rclone has more protocols but not a real graphical interface.

    Simpler but still as advanced as FreeFileSync. The JobSets tree gives a very clean overview for someone besides the original backup operator to take over the backup process. Also multi-platform and portable as FFS.

    very different in terms of purpose (backup vs sync), access (client vs network share/sftp...), storage (files vs volumes), complexity...

    Should not be in the list.
