If you have Kutools for Excel installed, you can apply its Track Snap utility to temporarily backup the current workbook with one click, so that Excel users can easily restore the backup copies.

1. Before your operation in Excel, take a snapshot with clicking Kutools > View > Snap > Track Snap.
Note: You can make multiple temporary snapshots by the Track Snap utility. These snapshots are sorted by backup time, and all of them will be removed after you close the current workbook.

2. And now in the opening Kutools for Excel dialog box, please type a name for the snapshot, and click the Ok button.

3. Supposing you have deleted worksheets or done other operations by mistakes, you can restore by clicking Kutools > Snap and then selecting a snapshot from the drop down list.

4. A dialog box will ask for your confirmation of restoring. Click the Yes button to go ahead.

Note: If you check the Don’t prompt me today option, this dialog box won’t pop out today when you reapply this utility. Then the current workbook is restored to the specified snapshot. In our case, the deleted worksheets are restored. See screenshot:
