Auto Backup Of Excel Files

You can use AutoRecover to have Excel automatically save a backup copy each time you save a workbook. The backup copy provides you with a previously saved copy, so you have the current saved information in the original workbook and the information saved prior to that in the backup copy. Each time you save the workbook, a new backup copy replaces the existing backup copy. Saving a backup copy can protect your work if you accidentally save changes that you don't want to keep or delete the original file.

1. On the Tools menu, click Options.
2. On the Save tab, select the Save AutoRecover info every check box.
3. In the minutes box, type or select a number to specify the interval for how often you want to save files.

The more frequently your files are saved, the more information is recovered if there is a power failure or similar problem while a file is open.

Note: AutoRecover is not a replacement for regularly saving your files. If you choose not to save the recovery file after opening it, the file is deleted and your unsaved changes are lost. If you save the recovery file, it replaces the original file (unless you specify a new file name).
