Simple local backup with rsync on Windows

If you already have rsync setup as a client on your Windows PC, you can also let it send files to any local folder/drive. In my case, I want to backup data on my PC to a USB drive.

ECHO Backing up the hard drive (eg: C:\DATA) to a USB drive (G:)
c:
cd c:\
rsync.exe -a --progress Photos ../g/Backup
