I don't have a CD-RW drive in this machine - I think I might have an old 4x drive somewhere which would do for backups. Alternatives include:

• Install samba and mount a CD-RW in one of my win xp machines
• Secure the backups with a password and ftp them to an external site (such as spookydistance developer account). This has the advantage that if my house burns down at least the source code will be saved (not that I'll give a shit about the source code at that point in time!)
