If you've put years, or even months or weeks of hard work into your blog, then you're going to want to back it up. You know .... just in case! There could be a server failure, maybe you accidentally delete your blog, or perhaps you've been falsely reported for violating Blogger's terms of service and you're shut down. It happens.
If you have a Blogger blog, then follow along. It's super simple.
1. Go to your dashboard. See the little wrench on the bottom left? That's your "Settings". Click on it.
2. When you click on "Settings" it will open a fly-down menu. Click on "Other".
3. Now you'll be looking at this image. Just click on "Export blog".
4. This pops up next. All you have to do is click "Download Blog".
5. After you click "Download Blog" you'll be given the option of where you'd like to save your blog copy. You can save it to your desk top, hard drive, wherever you like. I usually change the title so it's a little more specific. For example, I'd add GO or GradeONEderful to the beginning because I have several blogs. Be sure to keep ".xml".
If anything happens to your blog you now have a copy of your posts. To upload them you just repeat the first two steps. In step 3 be sure to click on "Import Blog", then upload the copy you've saved.
Don't forget to download a new copy every couple of months or so.
Hope this is helpful to someone. Have a great day!
