We've had some data loss and don't have a reliable backup it seems. We do have HUGE transaction logs and there was some thought that we might be able to use these to get back to a certain point.

Is it possible to help rebuild a database using transaction logs?

SQL Server 2008 R2, btw.

No. You need a previous image of the a database (ie. a reliable backup) to start from.

It looks like we found a .bak file from July. Not ideal, but it's something. –  spuppett Oct 28 '11 at 16:12
    
Thanks for your input. –  spuppett Oct 28 '11 at 19:48

As Remus Rusanu said, you cannot rebuild the database. It's bad, but it's true. But the data from your log can be extracted by tools like Lumigent LogExplorer. I understand, that it is very litle possiblity that it can help, but maybe this is the way to extract something that you need.

+1 There are some incredible tales of recovery from impossible situations. A percentage of the data may indeed be recoverable, if it has sufficient value to warrant the effort to recover. –  Mark Storey-Smith Oct 28 '11 at 21:30
