This Disk Image (or DMG) is an exact copy of your hard drive, saved onto a separate external hard drive. Backing up your Mac from a failing hard drive - and recovering missing files from it - has never been easier. To get started backing up your Mac and taking a snapshot with all of the contents of your hard drive, start Disk Drill. From the list of available volumes, click on the hard drive that is showing signs of trouble. To the right of the hard drive name, click on Extras, and then "Backup into DMG-image." A "Save" dialog box then appears. The default location is the user folder on your computer. However, it is not a good idea to save a copy of a failing hard drive on that same failing hard drive. It is much smarter to save a copy of your hard drive onto a second, unrelated hard drive. That way, your backed up data will remain secure, even after the original hard drive fails. So connect a sufficiently large external hard drive to your computer (CDs, DVDs and flash drives are generally not large enough to hold all of the information stored on today's hard drives). In the "Save" dialog box, click on the black arrow on the upper-right, next to the hard drive name. You will now see a list of folders and disks. On the left side of the dialog box, click on the name of the external hard drive that you just connected, then click the Save button. If Disk Drill warns that the external hard drive does not have enough space, either free up space on the external drive by deleting files, or find another hard drive with more space. If there is sufficient space, Disk Drill begin backing up your Mac, making an exact copy of your hard drive on the external drive. This process is time-consuming, so sit back and relax while Disk Drill does the heavy lifting. Once the copying process is complete, on your external drive you will have a large DMG file that has the name of your main hard drive. This OS X backup DMG file is an exact copy of the data on your hard drive. Everything is included in this file, even live files and "empty" sectors that need data recovery in order to be read. Now you can recover files from the copy you just made. The DMG file is treated by the computer as if it is a "real," physical disk. To mount the disk, either double-click the DMG file icon in the Finder, or use the "Attach non-mountable disk image" option in Disk Drill to select the DMG file. Once the new disk shows up in Disk Drill, you can click the "Recover" button next to its name and start the recovery process. Now you know how to backup your Mac. You can now relax knowing that even if your failing hard drive stops working completely, you still have an exact copy that will preserve your vital data.
