Maybe clonezilla?

Currently using portainer to run

• freshrss
• syncthing
• samba share While plugged into an external 3tb expansion drive. I want to do more but i only have a 2gb version so im afraid i might be pushing it.

It honeslty depends on what you do and want. I use syncthing instead of cloud services to bavk up everything i need and because i play emulated games a lot on both pc and my steam deck i can essentially have cloud saves for them.
