Yes, it is the overall ease of configuration, operation - but also for me the app ecosystem.

Well, my Synology NAS is from... 2013 (have upgraded the drives 3-times), so... it is/was time to replace it, and I can tell you that it won't be with another Synology device...

I won't go back to QNAP, which is what I had before Synology, because during an OS update it wiped all my data (yes, there was a warning, but the whole purpose of having a RAID NAS is safe reliable data storage)

May check-out a custom hardware build, combined with Xpenology.

Important story to note - it's not a backup if you don't have more than one copy of it (beyond multiple copies on one NAS).

I have a stack of old harddrives in external enclosures - as I upgrade (non-failed) drives, I buy another enclosure and then do backups that way. So far, over 30-years, it has proven to be more reliable than burned media (I have even had to help clients who had project source code succumb to "bit-rot" on their physical burned media, but I still had a project HD tucked away from 15-years prior)
