Does Clockwork Recovery Overwrite Previous Nandroid Backup

[.46caliber]

I created a Nandroid backup using Clockwork of my Moto Droid, OTA 2.2.1, before installing Cyanogen via ROM Manager. If I wanted to make a backup of Cyanogen to try another ROM, will it overwrite the stock backup that I made? Or does Clockwork allow you save multiple Nandroid backups?

I use Clockwork via rom manager, running Cyanogen on my (original) Droid. It does multiple backups. You should be fine
