+1 for PBS and it's dedup capabilities. I run a remote sync with it to offsite, along with ZFS reps of the underlying datastores.
As for Proxmox itself, I haven't bothered with backing the nodes themselves up, it's so simple to set up and cluster that if it went down, it would be a good chance for a nuke and pave, and restore VMs.
I don't know how that Synology DS423+ could consume 50W idle.
It seems veeery strange to me. I mean, my E5-2620 V2 on a 10/15 years old Supermicro motherboard with 16GB of RAM, 4 idle SATA 3,5" hard drives and 2 SSD is consuming 55W!
Something doesn't sound right to me.
My simple itx 2700X server with 2 HDDs was idling significantly less than 55W that his synology was and it isn't even have low idle power consumption like the synology.
Definitely something off with his method or configuration.
Synology... and HDD hibernation don't really go together very well. If you have containers running, it won't let the HDDs hibernate at all. And- I have a minio instance running.
Yeah, it's good to see actual data to back up claims, and TBH, justify what some of us were probably thinking, but didn't have the time / motivation to research... like many Ras Pis vs 1 traditional PC.
