Medic-49

I'm hosting a server through HFBServers.com Dallas-49 Ive read that it is a good idea to restart your server every 6-8 hours to keep it running smooth. I have only done one restart on the server, and somebody told me later they lost a vehicle they had fixed. If I manually restart the server through the HFBServers.com control panel, does this reset spawns, + saved things such as tents / vehicles? I'm new to hosting to bare with me please! Many thanks - Medic
