I just came across this via PC Mag and was so impressed that I installed it straight away. It was certainly quick and easy.
Backup To EMail v1.3.1 [10.9M] [Win 98/ME/NT/2K/XP] [FREE]
Backing up is something we all need to do, but not many of us really do it. The reason we do not like to back up is it takes too much time. You have to bother with thinking about doing it, and then planning how you are going to do it. You have to figure out when to do it, and how often you should do it after that. It should not be this hard. Thanks to Backup To EMail, it no longer is. This freeware program is brain dead simple. "Back up immediately any file or folder to your email account. You simply right click a file, choose "backup to email," and it's being sent to your email account. "There is no limit on the file size you can upload; it's being split automatically for you. You enter the details of your email account only once. As email boxes grow in size (Gmail = 3GB, Hotmail = 2GB, Yahoo! = 2GB), people are using their mail boxes to back up their files; this software's main aim is to help you do it very quickly in a simple right click on a file. When you enter in the settings screen the email address where you want to back up files, then the rest of the details (like outgoing SMTP server, if it requires authentication, SSL) are entered automatically for you for known mail servers." If you use your own mail server account (for example, if you have an email in your university) then you can simply fill in the details of the mail server according to regular settings of any other email client like Outlook Express, Eudora, etc. Version 1.3.1 includes the ability to back up folders. When it comes to backing up, you can never have enough utilities in your tool belt. You may just consider this program one of the most useful ones you can get.
