Cobian Backup is freeware. It can be used for personal and
commercial purposes. This program was created in 1999 and has been
updated several times every year in my free time.
To keep the program free and alive, you can help me by making 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.
