backup questions

I want save a copy of the entire mysql database on the server once a day. Then have backup copies older than 7 days deleted.

So I set up the ‘file on server’ like this?


then I am saving it with the ’ Single archive file’ checked (and the strftime-style time substitutions checked)

Do I need to include an extension on that file name? If so, what?

Does it save in a propriety virtualmin way, or is it in sql so I can unfurl it on another mysql db even without vm?

Thanks for any help,


Did you search the forum? You probably missed this:

Ok, but I’m still not sure about whether to add an extension or not… experimenting…

Looks like I don’t need the extension.
