_It's very easy. In your site editor, make sure you're on the SETTINGS tab, select ARCHIVE/UNPUBLLISH. Select "DOWNLOAD YOUR SITE AS A .ZIP ARCHIVE." Wait a bit, and you will be prompted to save your zip file to your computer.
An archive is helpful if you make a drastic mistake in some part of your existing site. You can't re-upload it to weebly, but you can . . .
_Not exactly. You can't download an archive of the site to your computer, but GoDaddy does back up your site when you first publish it, for later versions if you select that feature when you are publishing a change to the site online, or when you select MANAGE>BACKUP/RESTORE, enter a name for the backup and click SAVE WEBSITE. (Do back it up!) Make a backup of your existing, even messed-up site before restoring, just in case.
Complete restore: if you have a disaster, GoDaddy lets you restore your site completely from one of up to five backups, however there is no way to select just one page or block to restore using this function.
Partial restore: this workaround is especially helpful if you've messed up just one block (or just a few) while doing major changes to your site, but it needs to be done carefully . . ..
_Weebly is not great with the undos. I think it's their automatic save that is the culprit here. Usually that auto save is a very good thing — otherwise we'd be saving each little step in each little section, which could be positively crazy-fying.
Text: In the case of text, as long as you don't navigate out of the text section you are working in, you can often still press COMMAND-Z (Mac) or CONTROL-Z (PC) on your keyboard to undo what you've just done, just as if you were in a word processing program. But navigate that cursor out, and it's saved as-is.
Deletes: In the case of deleting something you want back, that's where the "not great" comes in. It's deleted.
The first thing I had to learn with Weebly was to slow down and try to be very present and zen-like, so I did less un-undo-able things. The other thing I learned was . . .
