Yes, you may be able to restore your page using Snapshot Backups. When you create your site, you automatically activate Snapshot Backups, which stores a copy, or takes a "snapshot," of your web site files every four hours; nightly; and weekly. You can usually use this tool to recover lost files. Learn how.
Because snapshots are taken only every four hours, a file that existed for less than four hours will not be recoverable. Snapshots are also removed after four weeks; files older than four weeks old cannot be restored. For this reason, we encourage you to back up your files on your own computer as extra security.
Important: Snapshot Backups saves a copy of your file during each interval only if that file has changed since the last backup. It does not create a copy of your entire web site with each snapshot
If you created your site with SiteBuilder or a third-party tool, you should already have a copy of your entire web site stored locally (on your computer), unless you deleted it. To back up files from a site you created with a Yahoo! Wizard or PageBuilder, or online with one of our code editors, you can back up your files using FTP or manually.
FTP
FTP is a quick way to save your pages that also prevents you from accidentally downloading any code that doesn't belong to your pages (code from a Yahoo! page, for example) and allows you to copy not only your web pages but also your images, audio clips, and other files. Learn more about FTP.
Copy your page code manually using File Manager.
This option will allow you to back up the code used to create your web pages; it will not, however, enable you to copy your images and other site assets, and the process will take significantly more time than downloading your pages with FTP.
You can repeat this process for each file you want to back up. We recommend that you keep a backup of all of your files on your own computer.
