Don’t be evil - Google

I’m running Urbackup in a Dietpi VM, with 256Mb RAM. Works fine.

Urbackup server is running about 70Mb RAM idle.

I could probably go down to 128Mb for the whole VM, but that’s is pointless and it might start to struggle during a backup session.

LMS is also pretty damn light as well. Uses about 19 MB of RAM on my system on idle.

Lightweight Music Server

Works for me on my desktop. Latest kernel. USB Bluetooth stick.

Might depend on the hardware.

Bluetooth seems to be some kind of black magic. Difficult to get right.
