When you back up a PC, O&O DiskImage saves all personal files as well as hard drive information and individual settings. This not only protects irreplaceable files but, in a worst case scenario, also saves you the trouble of having to carry out a time-consuming new setup of programs and the Windows operating system. O&O DiskImage lets you back up an entire computer, system and hard drives or just individual files and folders. To make sure your backups are always up to date, we recommend creating them at short intervals from one another.
