Yes updating is part of it, but at least on my current setup (using just the old laptop with limited storage) it often includes stuff like extending the partition for a VM. I understand that this is probably not a problem, when using a NAS with several TB of storage though
The thing is I don’t want to invest in one of those while I am still unsure about which route to go.
Also stiff like connecting to a service from outside my home network isn’t configured right now due to security concerns (stemming from the actually very little knowledge I have setting all this stuff up). I will look into tailscale though, maybe having this feature will give me a motivation boost :D

Thank you for actually explaining why it’s not suitable
I will look into those should I decide to keep this setup running

thank you, i will look into that

thank you
that still leaves the part about all the hassle of maintaining every service on its own though

that was my reasoning as well: with HA OS it is as little trouble for me to maintain - at least that was my line of thinking

thank you
a friend has nextcloud setup, i will ask him about it / try his setup regarding performance

that would only handle the backups (and possible data loss) right?
all the tinkering about the specific services is the same on unraid isn´t it?

currently i am doing them manually everytime i am changing something. I had to deploy them before (successfully) but if i am going to keep going with the selfhosting route i am planning to set up syncthing to the NAS of a friend
