A database dump is a file with database contents and special commands used to re-create its complete copy on another server. So, a dump is a backup copy of a database, which you can use to restore your database to the state it was in when the dump file was created.
On your server
You can obtain a database dump by using a database management tool in your web-hosting control panel. Quite often popular web application phpMyAdmin is used for this purpose by web hosting companies. Use the Export tab in that web app to download a dump file to your computer. During export, you can optionally select the exported file to be automatically compressed to a ZIP or TAR.GZ archive.
On Webasyst Cloud
You can obtain a database dump of your account in the Cloud app or in the Customer Center’s section “Account” via the “Backups” link.
On the page opened by that link, use the “Download a database dump” button.
