Can I Sync Synology NAS to External Devices?
I have a folder on the NAS called "Pictures". That folder has several subfolders. "Sorted" is all the finished and indexed stuff. There's "New pictures" and "2019 Unsorted" and "2018 unsorted" etc. And I want to sync the entire Picture folder to USB drive so when I sort name of pictures in the annual folders and drag them into the "sorted" folder, the sync-folder on the USB drive will replicate the changes.
There was the "Shared Folder Sync" that seemed perfect, but it apparently only works NAS to NAS. Is there a simple program to sync Synology NAS to external USB drive? I'd really like it to be on the Synology to exclude any slowdowns on the network by syncing it via a computer.
