After 17 years I dropped Synology recently. I sold my 2 NAS. Company changed focus. Did not like the walled garden and old linux base.

I moved to a second hand beefed-up laptop and a terramaster disk pack connected vi USB. Same wattage.

It does take some effort, but now it is done. I like to tinker anyway. I pulled up Proxmox with a bunch of containers doing SMB/SNF per share.

Just like with Synology, I just look a regular emails with successful backups. edit: typos
