how to backup mac to synology over internet

I'd have no issue at all using it as a backup solution to a BTRFS volume on a Synology, and then using scheduled snapshots on the volume to give me depth-in-time incremental backup points.

Having said that, it's *very* fast to do it's pre-sync comparisons, and I really like the GUI interface. Not terribly slow, just not necessarily as fast as it could be. I've used FreeFileSync in a number of ways for a number of years, and found it to be very reliable, but not necessarily very fast (raw transfer) on either Win or Mac clients. What other recommendations do you have that would be single solution for MacOS and Win and allow me to backup that content to C2?.Does anyone have experience with FreeFileSync with Mac and Win clients to Synology NAS?.Another requirement is that I be able to backup the client backups to Synology C2. I'd like to have one solution for all clients. TimeMachine is an option for the Macs, but not for Win clients.

So now I am considering alternative clients for either backup or sync options. (Plus the interface and control options are very 90s-ish.) The throughput of SDC is veeerry slow and now I've seen this is a common complaint of SDC for both MacOS and Win clients. Since Active Backup for Business doesn't have a Mac client, I've been working to setup Synology Drive Client (SDC). I have three MacOS clients and two Win clients. I have a DS920+ for a home/home office network.
