Recovering deleted Virtual Item Groups from eB Web document.

A Virtual Item Groups was accidently deleted from a document on eB Web.

I need assistance on how to recover it back to the document.

We did have daily eB database backup, it's just I don't know how to extract that particular deleted document from the SQL server and restore to its original location.

Currently we are using eb Web ver. 6.3.2.115 / 15.6.1.115

Appreciate your kind help.

Thanks.
