Creating Backups
Another ally in the war against major catastrophe is the backup. Using the Save As command, you can save a copy of a file. Save As does more than create identical copies; you can also use it to save a copy in another color mode (for instance, create a copy in CMYK color mode and keep the original in RGB color mode) and another file format.Here’s how to create a backup:Choose File>Save As or press Ctrl+Shift+S/z +Shift+S.The Save As dialog box appears, as shown in Figure 7-2.

Type a new name or modify the existing file name in the File Name text box (Windows) or Save As text box (Mac).
Select a folder where you want to save the backup.
If you want, choose a different file format for the backup using the Save As drop-down list (Windows) or the Format pop-up menu (Mac).
| Remember | If your image file contains layers and you choose a file format that does not support layers, the Layers check box is grayed out and the backup copy is automatically flattened. |
In the Save and Color areas, select any options that you need.If you select the As a Copy option, the image copy remains closed and the original remains open. If you want to include a color profile with the backup, select the Embed Color Profile option (Mac) or Color: ICC Profile option (Windows). (To find out how to create a color profile, turn to Technique 4.)
Click Save.If you click Save and you haven’t changed the name of the backup copy from the original, the Adobe Photoshop dialog box shown in Figure 7-3 appears.

Click OK to save over the original file or click Cancel to return to the Save As dialog box where you can change the backup copy’s filename.
