What is an unprivileged LXC container in Linux?
I.e. of a kernel feature that allows to map a range of UIDs on the host into a namespace inside of which a user with UID 0 can exist again.

Is there a way to overwrite an LXC container?
You can overwrite the previous container with the restore, but it might be a safer bet to just create a new container and then shutdown your old one. You can also do this through the GUI by navigating to the backups of your container, selecting your backup, and clicking restore.

Why do we need Unprivileged containers in Proxmox?

See the Proxmox documentation on unprivileged containers for more information.
