Any tools for database verification and manual restore?

Hey, 

Are you using the SQL Server as a backbone, or is this a Firebird-based system? 

If SQL Server-based system, where is the file data located? Is it inside the SQL database? 

Hello,

We are using the SQL server. File data is located outside

One way would be to restore the document vault with a separate identifier (guid) from the previous backup where the file was still not destroyed. I hope you also have backed up the file data at the same time? 

Then, from the restored vault, do a one-time export of this document and import the document to the production vault. 

We have tried exactly that, except that we had to create the restored vault with the same identifier because some error was not letting us create it differently, but the problem then occurs on the file itself with it's Delta versions. Are there any data verification tools available that we could use?
