Are download-only cloud backups nondestructive?
I'd like to use the cloud backup services built into ReadyNAS to make local copies of anything placed into my Google Drive and Dropbox services, but I don't want deletions to be synced. In the past I've used third party software (rclone) to configure nondestructive backups of cloud services, but I don't see any indication of whether the ReaadyNAS download-only cloud backup will also delete files locally when it detects deletions on the remote cloud service.
Does the ReadyNAS download-only cloud backup sync deletions by default? Is there a way to configure the ReadyNAS download-only cloud backup for nondestructive backups?
