Cobian Reflector is freeware. It can be used for personal and commercial purposes. This program (as Cobian Backup) was created in 1999 and has been updated several times every year on my free time.
Some of the components that I use (like the SFTP engine) have been
purchased by me to be used with the application. The hosting of the web
site costs some money as well.
To help keeping the program free and alive, you can help with a donation
to my PayPal account. If you have a PayPal account as well, you just do
the transaction from PayPal to PayPal. If you don't have an account with
PayPal you can make the transaction from your credit card. PayPal encrypts
all information between you and their servers using SSL.
