This is a howto describing an unattended installation of Cygwin including both Rsyncd and SSHD. Rsyncd is there to make your backup setup from the BackupPC server more simplified. No setting up SMB shares or any business, just use one master rsyncd.conf file with all of your shares for all of your servers and you're in business. The sshd is intended to allow you to execute remote commands. This can be useful if you want to dump a database or setup a VSC to pull from instead of being denied access to open files. Relavent links can be found at the bottom of this howto.

• A central share to store all of your files - should be heavily guarded
