One of my customers has caused a problem with their database (a large portion of the data has been deleted). They haven't made any regular backups unfortunately. Is there anyway to use the transaction log to "roll back" the changes that caused the problem? Can I backup the database and restore up to a point with the transaction log? I tried a point-in-time restore, but it won't let me go back prior to the time of the backup I made. HELP!
