I deleted a tif image file that I didn't intend, which had several virtual copies of LR, created from it. Virtual copies had a lot of history important that my impression of the preparation of changes to the document. These virtual copies are saved in the LR backup?

If so, how can I insert in the catalog that I use? I did a lot of changes in the two days since my last backup and don't want to lose this story either. Are you suggesting that I do a backup current prior to extraction of files since I last saved? I know I'm supposed to go to the backup location and open the last backup, but how work with the work during the last 2 days?

Any help would be most appreciated. Thank you, Tom
