Windows Client Backups with rsync and FreeBSD

Sys Admin Magazine

[this] solution uses rsync over an encrypted ssh connection to synchronize a subset of the files on the customer machines (we don't need to archive applications and operating systems, just working files) with a live copy on a FreeBSD server. The server keeps the live copy on a RAID-5 array of disks. The RAID-5 is designed to protect the server copy from the very failures from which we are trying to protect the clients. Customers have a single "Backup Now" icon on their Windows Start Menu, and they initiate backups at will, background the process, then go right back to work.
