I deleted a tif image file that I didn't intend to, which had several LR virtual copies created from it. The virtual copies had a lot of important history that document my print preparation edits. Are these virtual copies saved in the LR backups?

If so, how can I insert them into the catalog I am using? I have made a lot of edits in the two days since my last backup and don't want to lose that history either. Do you suggest I make a current backup before retrieving files from my last backup? I know I'm supposed to go to the backup location and open the last backup, but how do I blend that with the current work from the last 2 days?

Any help would be most appreciated. Thanks, Tom
